11 Appendix LED indications

11.1 System Module LED indications

The System Module has seven tri-color LEDs on the front panel to indicate the

operational status of the module and all fault conditions during operation. See Figure 78:

System Module LED positions for the System Module LEDs.

Figure 78 System Module LED positions

The FPFA has four and the FPFB five additional LEDs on its front panel. The LED indications of the System Module are listed and explained in Table 3: 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.

Table 3 System Module LEDs (from left to right)

LED Color

FSMC/FSMD/FSME only:

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

Fan status

System Module status

Yellow: Stand-by, output disabled Green: Normal operation, output enabled Red: Fault, output disabled

Yellow, blinking: Remote controlled, output disabled

Red: Fan fault Green: Fan OK

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

Red, blinking: Minor alarm

Table 3 System Module LEDs (from left to right) (Cont.)

LED Color

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

RF Module 1 fiber connection status (OPT-RF1)

RF Module 2 fiber connection status (OPT-RF2)

RF Module 3 fiber connection status (OPT-RF3)

System Extension Module 1 fiber connection status (OPT- EXT1)

System Extension Module 2 fiber connection status (OPT- EXT2)

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

Note that the FTFA unit has two additional radio-specific LEDs on the front panel.

11.2 RF Module and Remote Radio Head (RRH) LED indications

The Flexi Multiradio RF Module and Remote Radio Head (RRH) have two tricolor LEDs on the front panel to indicate the operational status of the module and all fault conditions during operation. A blinking red LED does not always require removing the module.

The Flexi Multiradio RF Module LEDs are:

Module Status - indicates the status of the RF Module core functional block

Fan/TX Status - indicates the fan and TX status The Remote Radio Head (RRH) LEDs are:

Module Status - indicates the status of the RRH functional block

TX Status - indicates the TX status of the RRH

A red, blinking LED does not necessarily mean hardware failure. Always perform troubleshooting before replacing the module.

You can identify faulty Flexi Multiradio BTS modules with the respective Flexi BTS Site Manager. In the Alarms window of the respective Flexi BTS Site Manager, you can see the object that the alarm refers to in the Object column. It is not always the alarming module that is faulty, it may also be the connected cable or the interworking module that causes the alarm.

At the site, you can easily locate the alarming module by checking the color of the LED.

See the LED status indications tables for information of LED status.
