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.

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

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 areoperational
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 RRHA 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.
