Memory Module installation or replacement
Important:
Always
power-down
the system (
all
cabinets)
before
adding or replacing the Memory Module.
Also, be sure to observe all proper procedures regarding the prevention of electrostatic discharge (ESD)
when performing the following procedures otherwise circuit boards may suffer damage.
LED functions
The unit's various LEDs are designed to provide visual feedback as follows:
Power LED
The
Power
LED is located on the left side of the system’s faceplate, and is illuminated when power is being
applied to the system. This LED blinks periodically to indicate that the main processor is operational.
LED appearance
What it means
Solid red
Boot-loader is running and loading the FPGA
Solid green
System is loading DSPs
Rapidly flashing red
Boot-loader is loading call processing into memory
Solid green
System is reading configuration and loading port cards
Slow red “heartbeat”
System powered up and ready
Activity LEDs
The
Activity
LEDs are located above their respective connectors on each installed module. Each LED is
illuminated when any port on its associated module is in use.
Note:
Disconnecting a connector when its respective LED is lit will disconnect any of its ports that are in use.
Upon power-up, approximately five minutes are required for the system to configure. The
Power
LED will
flash red periodically, like a “heartbeat”, to indicate that the power-up sequence has been completed.
Note:
When a T1/PRI Module’s LED is…
…not lit at all, the T1/PRI circuit is in service but is idle.
…lit solidly, the T1/PRI circuit is out of service.
