See Figure 4 Front panel of the FSIA Flexi System Module Indoor for the System Module LEDs.

The LED indications of the System Module Indoor are listed and explained in Table 9 System Module LEDs (from left to right).

It is recommended that you read the information on the LED indications carefully. A blinking red LED does not always require removing the module.

t You can inspect the state of all BTS or transmission-related alarms from the LED on the transmission sub-module.

LED Colour

PWR status (one LED for internal and each external power output)

• Yellow: Stand-by, output disabled • Green: Normal operation, output enabled • Red: Fault, output disabled • Yellow, blinking: Remote controlled, output

disabled

Fan status • Red: Fan fault • Green: Fan OK

System Module Indoor status • Red: Module self-test or reset (LED red for < 5 seconds) or major alarm or critical alarm

• Red, blinking: Minor alarm • Yellow: Stand-by or blocked • Yellow, blinking: SW download or configuration

ongoing, module non-operational • Green: Module operational (the cell can be

locked in the RNC) • Green, blinking: Module is loading software or

parameters or local maintenance access when modules are operational

7.2 External Synchronization Output Interface connector pin map

Figure 6 MDR14 connector

The Sync out connector pin map is presented in Table 11 External synchronization output interface connector (MDR14).

Signal descriptions:

• 2M_out: 2.048 MHz clock reference output (ITU-T G.703/chapter 13) • The signal comes from the Flexi transport part, which is locked (PLL) to the Iub

interface. • The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin

7 and cable shield to GND (for exalple pin 14). • Testclk_out: 10MHz system clock (LVTTL)

• The signal comes from BTS OCXO which is used for air I/F generation => refer-ence for the RF measurement equipment.

• Note: the BTS OCXO is not in the PLL mode to the Iub, the locking is very loose due to air I/F stability reasons.

• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin 11 and cable shield to GND (for example pin 10).

• GND: signal ground, for asymmetric signals
