D.TEACHER’S SELF-REFLECTION OF THE SESSION

At the end of the session , evaluate the result of the performance of the trainees, if the result is not good thenask the trainees what are the problems they encountered? What part is difficult for them to perform? So thatthe trainees can suggest what intervention the trainer can do to help them better understand and guide them

to improve their efficiency and effectiveness in their performance.

Other trainees have to practice more on how to terminate UTP cable to RJ-45 effectively. The methods workedsuccessfully and effectively to the trainees even if most of them were high school graduate.

Testing Normal Function of Systems and Networks



1.Check normal function of systems and networks in accordance withmanufacturer’s instructions.

Modern-day PCs are more reliable than ever before, but that doesn’t mean they’re infallible. Equipmentfailures will still happen, however rarely, and even the beefiest of computer components aren’t worth their weight in silicon if they aren’t dependable. Thankfully,the hot and heavy world of stress testing can help toidentify critical faults before your PC crashes out in

the middle of a critical operation.

Whenever you buy or build a PC, swap out a major component, or overclocka piece of hardware, it’s a good idea to stress-test ( or “burn in “) the freshgear, which is not the same as benchmarking your rig.

Why stress-test? Simple: To ensure the reliability and stability of yoursystem. Even if a computer boots up and performs well under normalusage, fickle hardware can cause woes when you step up to heftier tasks,such as gaming or video editing. Stress-testing software places yourcomponents under an intense workload to simulate a worse-case scenario; Ifa component crashes, hangs, or otherwise fails a dedicated stress-test, thereis a good chance that it won’t be reliable under a heavy everyday loads. It’s best to uncover unstable components sooner rather than later, while they’restill under warranty.








54/198

Running stress-test can also let you know if you need additional cooling in your computer. If a graphics card or overclocked CPU consistently overheatsand shuts down during a stress test, it’s time to dump the stock cooler, add

a few case fans, and possibly even consider liquid cooling.

All that said, the actual process of stress testing isn’t terribly complicated,though it can be time consuming.

Laying the groundwork.

Here’s a look at HWMonitor and SpeedFan’s interfaces side-by-side.

Before you start torturing your PC, you’re going to need a way to keep tabson its screaming. CPUID’s HWMonitor software does exactly that, providing you with a real-time glimpse of your components’ temperatures, voltages,and fan speeds. Speed fan does the same, though its interface isn’t quite aspolished as HWmonitors.








55/198

You’ll want to have at least one of the two programs open during stress tests. While many components will automatically shut down if they overheat, notall will, and you want to pull the plug on you testing if your hardware hits

dangerous heat levels. You can fry your components if a worst-case scenariooccurs and you’re not paying attention. If you see CPU temperature startingto creep north 70 degrees Celsius, or graphics card temperatures around105̊C stop the test and add more cooling to your computer. You’ll also wantto halt your testing if temperatures continuously hover around those marksfor an extended period of time.

Before you start your testing, I recommend closing any nonessentialprograms and diving into your system’s Power setting to prevent it fromgoing to sleep. You don’t want your computer to doze off while you’re busy

burning it in. if you use a screensaver, disable that too.

Testing the CPU with Prime95

If you stress-test only a single component, stress-test your CPU. T’s thatimportant- and it’s frequently the culprit behind an unstable system.

Prime 95 includes three different “ torture “ tests.

While a handful of programs are available that can stress your CPU to itslimits, Prime95 has become thede factostandard. Ostensibly, designed to








56/198

findMersenne prime numbers, the software absolutely hammers yourprocessor, to the point that the developers now include a dedicated “ Torture Test “ mode for peole who are interested in system stability than complex

mathematics.

Open the program, then head to options > Torture Test to bring up a list ofoptions. Many people use theBlend Test. Blend stresses both the CPU andRAM; if no errors pop up after four hours or so, you can consider it stablefor normal use. Alternatively, theSmall FFT andLarge FFT torture tests layoff the RAM a bit to subject the CPU to as much respective stress and heatas possible.

If you have the time ( an adequate cooling ), feel free to “ Torture” your PC with Prime95 for juch, much longer, particularly if you plan to use yourcomputer for folding @home-type projects, which can consume a ton of CPUresources for extended periods. Prime95 sometimes catches CPU errors evebafter half a day of testing. If your rig can run Prime95’s Small FFT test for afull 24 hours without issue, the CPU is as solid as a rock and ready to fold.

IntelBurn test is a nonofficial, user-friendly version of Intel’s brutal Linpack benchmark.

Want a second opinion? Different programs test CPUs in different ways.Hardcore types also hold IntelBurnTest OCCT-two other CPU- stressingprograms in high regard. Both hit your processor- hard and ramptemperatures up very rapidly, however, so keep a close eye on your system-monitoring software when you start the.

No matter what testing program you choose, run it for at least four hours; afull overnight run is preferable. Personally, I like to stress-test new PCsusing Prime95’s Blend and Small FFT tests for at least twelve hours a piece,

and I sometimes follow it up with an hour-long,High or Very High stresslevel IntelBurnTest run.

Testing the RAM

When it comes to seriously testing RAM, only one option is worthconsidering : Memtest 86 +. This tried-and-true diagnostic software has been around seemingly forever, and while it definitely looks its age-








57/198

Memtest86+ rocks an ugly BIOS-esque interface- the program is just aseffective now as it always has been.

A bad memory module (RAM) can cause unpredictable behavior in a Windows system, including the dreaded blue screen of death. If you suspectthat your RAM may be faulty, you can run a memory test to confirm that you have a bad memory module.

Laptop and desktop PC makers occasionally provide preinstalled utilitiesthat sometimes include a memory test. Feel free to try out these utilities,especially if your computer is under warranty and you want to make a warranty claim. Manufacturers will often require you to run their supportutilities first, before agreeing to replace hardware or more forward with a

trouble ticket.

We are going to use a widely-used memory testing application calledmemtest ( memtest86+). Reputable memory makers like, Corsair, PatriotMemory, Crucial, and others, recommend memtest to test their memoryproducts.

1.Get memtest

To use memtest, you have to download it and crearte the bootable mediafirst. You’ll need to decide whether you want to download the ISO image fileand create a CD/DVD or if you want to download the auto-installer for USBkeys to create a bootable USB flash drive.2.Create memtest bootable media

If you want to create a memtest CD or DVD, unzip the download ISO anduse your favorite ISO-burning program to create the disc. In windows 7,simply right-click on the ISO file and select “ Burn disc image’, then follow

the directions to create the disc.

If you want to create a bootable memtest USB flash drive, run the auto-installer and follow the directions to create the drive. Just make sure that you use a blank flash drive; rthe installer will erase all the files on the drive.








58/198

3.Run memtest

To run memtest, start your computer with the bootable media inserted andthe test will begin automatically. If you’re having problems booting themedia, make sure that the boot order in your system’s BIOS is set to bootthe optical driver or USB flash drive ahead of your hard drive.

If you have more than one memory module, we recommend that you test onemodule at a time, using the same DIMM slot on your motherboard. This willhelp you isolate the problem module.

The eight different tests in memtest can take several hours to complete,depending on the size of the RAM. A successful test will complete withoutany errors. A failed test will report errors in the error column and you’ll seelots of red blocks.

If your RAM fails memtest, that should be enough for most companies toapprove a replacement. Keep in mind, however, that a failed memtest can








59/198

also be an imdication of problems with your processor, motherboard, ormisconfigured RAM.

Testing the Video card and Power Supply Unit . If you’re a gamer, stress testing your graphics card is a no-brainer,especially since graphics cards tend to fail under heavier loads- you know,like the other ones generated by top-end games. Another bonus: Graphictorture tests usually coax underpowered or faulty power supplies into givingup the ghost, so you’re stressing two birds with one stone.

Benchmarking tools abound, but FurMark was designed specially to give

your GPU a stress- nducing workout and punishes graphics cards muchharder than the average game. This bad boy uses real-time rendering offury objects undulating in front of groovy backgrounds to push yourgraphics card to its limits, complete with antialiasing and resolution options.Stick to the standard burn-in test, but keep an eye on HWMonitor and/soSpeedfan- FurMark gets your GPU very hot, very quickly. You won’t need torun FurMark for long. If your graphics card is going to crash or start tossingout funky visual artifacts, it will do so within 15 to 30 minutes.

Test Network Connection with Ping and PathPing

Pingis a tool that helps to verify IP-level

connectivity;PathPing is a tool that detectspacket loss over multiple-hop trips. Whentroubleshooting , the ping command isused to send an ICMP Echo Request to atarget host name or IP address. Use Ping whenever you want to verify that a hostcomputer can send IP packets to adestination host. You cam also use the Ping

tool to isolate network hardware problems and incompatible configurations.If you callipconfig/all and receive a response, there is no need to ping theloopback address anf your own IP address- IPconfig has already done so inorder to generate the report.








60/198

It is best to verify that a route exists between the local computer and anetwork host by first using ping and the IP address of the network host to which you want to connect. The command syntax is:

ping

Perform the following steps when using Ping:

1.Ping the loopback address to verify that TCP/IP is installed andconfigured correctly on the local computer.ping 192.168.0.1If the loopback step fails, the IP stack is not responding. This might be

because the TCP drivers are corrupted, the network adapter might not be working, or another service is interfering with IP.

2.Ping the IP address of the local computer to verify that it was added tothe network correctly. Note that if the routing table is correct, thissimply forwards the packet to the loopback address of 192.168.0.1ping

3.Ping the IP address of the default gateway to verify that the defaultgateway is functioning and that you can communicate with a localhost on the local network.ping

4.Ping the IP address of a remote host to verify that you cancommunicate through a router.

ping

5.Ping the host name of a remote host to verify that you can resolve aremote host name.ping

6.Run a PathPing analysis to a remote host to verify that the routers onthe way to the destination are operating correctly.pathping

If your local address is returned as 169.254.y.z, you have been assigned anIP address by the Automatic Private IP addressing ( APIPA ) feature of








61/198

Windows 2000. This means that the local DHCP server is not configuredproperly or cannot be reached from your computer, and an IP address has been assigned automatically with a subnet mask of 255.255.0.0. Enable or

correct the DHCP server, restart the local computer, and see if thenetworking problem persists.

If your local address is returned as 0.0.0.0, the Microsoft MediaSensesoftware override started because the network adapter detects that it is notconnected to a network. To correct this problem, turn off MediaSense bymaking sure that the network adapter and network cable are connected to ahub. If the connection is solid, reinstall the network adapter’s drivers or anew network adapter.

Ping uses host name resolution to resolve a computer name to an IPaddress, so if pinging by address succeeds, but fails by name, then theproblem lies in host name resolution, not network connectivity. For moreinformation about troubleshooting host name resolution, see “ Unable toReach a Host or NetBIOS Name” .

If you cannot use Ping successfully at any point, check the following:

● The local computer’s IP address is valid and appears correctly in theIP

address tabof the Internet Protocol ( TCP/IP ) Properties dialog box or when using the Ipconfig tool.

● A default gateway is configured and the link between the host and thedefault gatway is operational. For troubleshooting purposes, makesure that only one default fateway is configured. While it is possible toconfigure more than one default gateway, gateways beyond the first areonly used if the IP stack determines that the original gateway is notfunctioning. Since the point of troubleshooting is to determine the

status of the first configured gateway, delete all others to simplify yourtroubleshooting.

Important:

If the remote system being pinged is across a high-delay link such as asatellite link, responses might take longer to be returned. The –w (wait)








62/198

switch can be used to specify a longer time-out. The following exampleshows a set of two pings, each 1450 bytes in size, that wait two seconds( 2000 milliseconds) for a response before timing out.

C:\> ping –w 2000 –n 2 –l 1450 172.16.48.10

Pinging 172.16.48.10 with 1450 bytes of data:

Reply from 172.16.48.10: bytes = 1450 time = 1452 ms TTL =32

Reply from 172.16.48.10: bytes= 1450 time =1452 ms TTL =32

Ping statistics for 172.16.48.10:

Packets: Sent= 2, Received = 2, Loss = 0 ( 0% Loss ),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 10ms, Average = 1664ms

Clear ARP Cache

If you can ping both the loopback address and your own IP address, the nextstep is to clear out the ARP cache and reload it. This can be done by usingthe ARP utility, first to display the cache entries witharp-aor arp-g.Deletethe entries witharp-d < IP address>.

Verify Default Gateway

Next, look at the default gateway. The gateway address must be on the samenetwork as the local host; if not, no messages from the host computer can beforwarded to any location outside the local network. Next, check to makesure that the default gateway address is correct as entered. Finally, check to








63/198

see that the default gateway is a router, not just a host, and that it isenabled to forward IP datagrams.

Ping Remote Host

If the default gateway responds correctly, ping a remote host to remove thatnetwork-to-network communications are operating as expected. If this fails,use Tracert to examine the path to the destination. For IP routers that are Windows NT or Windows 2000 computers. Use the route utility or theRouting and Remote access administrative toiol on those computers toexamine the IP routing table. For IP routes that are not Windows NT or Windows 2000 computers, use the appropriate utility or facility to examinethe IP routing table.

Four error messages are commonly returned by Ping duringtroubleshooting. They are:

► TTL Expired in Transit The number of hops required to reach the destination exceeds the TTL set by sending host to forward the packets. The default TTL value for ICMP

Echo requests sent by Ping is 32. In some cases, this is not enough totravel the required number of links to a destination. You can increase the TTL using the –i switch, up to a maximum of 255 links.

If increasing the TTL value fails to resolve the problem, the packets are being forwarded in a routing loop, a circular path among routers. Use Tracert to track down the source of the routing loop, which appears as arepeated series of the same IP addresses in the Tracert report. Next,make an appropriate change to the routing tables, or inform the

administrator of a remote router of the problem.

►Destination Host Unreachable This message indicates one of two problems: either the local system hasno route to the desired destination, or a remote router reports that it hasno route to the destination. The trwo problems can be distinguished bythe form of the message. If the message is simply “Destination HostUnreachable”, then there is no route from the local system, and the








64/198

packets to be sent were never put on the wire. Use the route utility tocheck the local routing table.

If the message is “ Reply from <IP address

>:n Destination HostUnreachable”, then the routing problem occurred at a remote router, whose address is indicated by the “” field. Use theappropriate utility or facility to check the IP routing table of the routerassigned the IP address of .If you ping using an IP address, retry it with a host name to ensure thatthe IP address you tried is correct.

►Request Timed Out This message indicates that no Echo Reply messages were received within the default time of 1 second. This can be due to many differentcauses; the most common include network congestion, failure of the ARPrequest, packet filtering, routing error, or a silent discard. Most often, itmeans that a route back to the sending host has failed. This might be because the destination host does not know the route back to the ost’ssending host, or one of the intermediary, routers does not know the route back, or even that the destination host’s default gateway does not knowthe route back.

Check the routing table of the destination host to see whatever it has aroute to the sending host before checking tables at the routers.

If the remote routing tables are correct and contain a valid route back tothe sending host, to see if the ARP cache lacks the proper address, usethearp-acommand to print the contents of the ARP cache. Also, checkthe subnet mask to be sure that a remote address has not beeninterpreted as local.

Next, use Tracert to follow the route to the destination. While Tracertdoes not record the address of the last hop or the path that the packetfollowed on the return path, it might show that the packet made it to thedestination. If this is the case, the problem is probably a routing issue onthe return path. If the trace doesn’t quite reach the destination, it might be because the target host is protected by a firewall. When a firewallprotects the destination, ICMP packet filtering prevents the ping packets








65/198

—or any other ICMP messages—from crossing the firewall and reachingtheir destination.

To check for network congestion, simply increase the allowed latency bysetting a higher wait time with the –w s witch, such as 5000 millisecond. Try to ping the destination again. If the request still times out, congestionis not the problem; an address resolution problem or routing error is amore likely issue.

►Unknown Host This error message indicates that the requested host name cannot beresolved to its IP address; check that the name is entered correctly amdthat DNS servers can resolve it.

Information Sheet 3.2-3Procedures in checking Faults or Problems



1.Diagnose fault problem in the systems and networks in line with thestandard operating procedures.

Procedures in checking faults or problems in the system:

Many people are faced with everyday computer problems that are easy tofix, but are unable to diagnose the actual problem. While there are manyproblems a computer will be faced with, this information sheet will tell you where to look for common problems.

Step 1:Check the POST. POST stands for Power On Self Test This is generally the first or second thing that appears on a computer afterturning on the power. This appears before the operating system begins toload. The POST will display any problems found with hardware that makesthe computer unable to boot, POST may also display problems with








71/198

hardware that allow the computer to boot but not operate at its full capacityduring operation.

Step 2:Notice the load time of the OS (operating system).

A longer than usual load time may indicate seek error (or other errors) in thehard drive.

Step 3:Notice any the graphics problems once the OS loaded

Reduce graphics may indicate driver failures or hardware failures withgraphics card.

Step 4:Perform an auditory test

An auditory test is an unorthodox, but still effective way of judging how harda computer is working. With the computer on and running, play anu decentlength audio file ( usually above 30 secs.). If the audio is choppy or slow, itusually means that the processor is working at an elevated level, or there isnot enough RAM to run all programs loading. Changing the startup sound isa great way to apply this test. Another issue associated with choppy sound is PIO ( ProgrammedInput/Output )mode. This affects how the drive reads and writes, and cansometimes repair choppy audio.

Step 5.Check any new installed Hardware

Many operating systems, especially Windows, can conflict with new drivers. The driver may be badly written, or it may conflict with another process. Windows will usually notify you about devices that are causing problem, orhave a problem. To check this use the Device Manager, this can be accessed by entering the Control Panel, Clicking the system icon, clicking theHardware tab, and clicking on Device Manager. Use this to check andarrange the properties of hardware.

Step 6. Check any newly installed software

Software may require more resources than the system can provide. Chancesare that if a problem begins after software starts, the software is causing it,








72/198

if the problem appears directly upon start up, it may be caused by softwarethat starts automatically on boot.

Step 7.Check RAM and CPU consumption

A common problem is a choppy or sluggish system. If a system is choppy itis practice to see if a program is consuming more resources than thecomputer can provide. An easy way to check this is to use the Task Manager,right click on the task bar select task Manager, and click the Process Tab. The CPU column contains a number that indicates the percentage of CPUthe process is consuming. The Mem Usage column indicates how muchmemory a process is consuming.

Step 8. Listen to the computer

If the hard drive is scratching or making loud noises, shut off the computerand have a professional diagnose the hard drive. Listen to the CPU fan, thiscomes on a high speed when the CPU is working hard, and can tell you when the computer is working beyond its capacity.

Step 9.Run a virus and malware scan

Performance problem can be caused by malware on the computer. Runninga virus scan can unearth any problems. Use a commonly updated virusscanner ( such as Norton Antivirus or Avast Antivirus) and a commonlyupdated malware scanner ( such as Spybot Search & Destroy )

Step 10.Check for the problem in safe mode As a latch ditch effort, check the problem in the safe mode. To enter safemode, tap F8 repeatedly during POST ( this works on most systems ). If theproblem persists in safe mode, it is a fair bet that the operating system itselfit to blame.

Procedures in checking faults or problems in the network:

There are a couple of basic commands to diagnose a network problem thatevery network admin needs to know.
