    Safety Precautions

    WORKING ON THE BUILDINGS ROOFDuring stormy weather, do not perform any mechanical assembling orantenna beaming (alignment) works on the buildings roof.The metal structure of towers/ masts is prone to lightning.

    ESD PROTECTIONAlways use proper antistatic protection when handling ESD sensitive parts.Protection is provided by means of a grounding bracelet, antistatic bags, etc.

    EXTERNAL OVER-VOLTAGE PROTECTIONEnsure the existence of external over-voltage protection (of rating thatexceeds 1.5 kV) at the input and the output of the indoor unit, prior to itsconnection to the network.Lack of external protection could cause damage to the equipment.

    1. Troubleshooting of Onsite Incidents

    Introduction This chapter deals with onsite incidents that might occur duringthe onsite installation, commissioning or maintenance of theequipment. A problem is usually notified visually:

    either through the activation of an alarm indicator (on thefront panel of the indoor unit), or

    through the unexpected behavior of the equipment (duringits power up process for instance).

    Basic trouble-shooting byhardwareswapping

    The following procedure is carried out when the field technician isnot familiar with the OmniBASs software alarms andtroubleshooting methodology, and there is lack of spareequipment (i.e. cards).By swapping equipment in a specific order, the field technician willbe able to localize the fault, provided that other collocated linksare readily available and that downtime is allowed.`The field technician must be able to correctly and accordinglyconfigure the following:

    Modem operation (protected / standalone). Modem parameters. ODU

    NOTE When swapping equipment, the field technicianshould be able to recognize what configurationchanges are needed to be done in order tosuccessfully re-establish the links.To avoid problems, technician should first carry outbackup of the initial configuration (prior toproceeding) and restore it as soon as he/she finisheswith hardware swapping troubleshooting.

    In the following two examples, we assume that Link A is up andLink B is down.

    Local trouble-shootingprocedure

    To carry out local OmniBAS troubleshooting, proceed as follows:

    Step Action

    1 Check for site power issues:Check whether OmniBAS is powered up and runsproperly. If yes, proceed to next step.If not, inspect the local DC power supply source.

    2 Check for impaired Ethernet cables:Visually check for activity on the OmniBAS Ethernet portused for carrying management traffic.In case of no activity, inspect Ethernet cabling andreplace if found impaired. Otherwise, proceed to nextstep.

    3 Check for impact on traffic:Make a local survey to check if services are affected.If yes (despite the fact that Ethernet cabling is not thecause of the problem), replace the OmniBAS controlcard (P7 procedure), or replace the whole OmniBASunit with a spare one (if available).

    4 Check for broken DCN connectivity:Use a laptop with appropriate Ethernet and IP settingsto locally connect to an external switch and ping theuni|MS Server / Host.If necessary, change the settings of the switch or makecorrective actions to the DCN equipment.In case of no ping response, resolve the DCNconnectivity problem using the respective DCNmanagement system(s).

    the OmniBAS Ethernet port.b. Connect a laptop with appropriate IP settings to

    the same OmniBAS Ethernet port.c. Ping the OmniBAS unit.

    Inband management connection:a. Connect a laptop with appropriate IP settings to

    a free outband management port on theOmniBAS unit.

    b. Check whether inband management VLAN ID: is associated with the correct Ethernet port

    used for inband management. has the highest priority over the air.

    c. Setup a Gigabit (GbE) or Fast Ethernet (FE) portto be used for inband management andconfigure for untagged traffic. Set as portsdefault VLAN the value shown next to VLAN IDfield in the Inband Management Parametersgroup box:

    (Right click OmniBAS NE > Configuration tab >Inband / Outband / RTC tab).

    d. Connect the laptop to the configured inbandmanagement port.
