Booting Up The Modem
When the modem boots up, all LEDs glow amber for 30 seconds. At this point, the bootcode is
initializing the hardware. A Power-On-Self-Test will also be performed, which includes a
bootcode checksum and main code checksum.
While the checksum test is running, dots will be displayed on the VT100 terminal.

3.1 Main Module Indicators and Switches

The 2361 modem main module has 4 LEDs, and one hardware reset
button. Main module LED function is explained below:

3.1.1 Main Module LED Function

STA: STAtus LED
Off Modem is not powered up or is in a failed
state
Solid Red Modem has failed
Solid Green Modem is active and is on line
Solid Yellow Modem is OK and is the redundant modem
in a redundant configuration
CFG: ConFiGuration LED
Solid Red One or more of the following reasons can be the cause of a red CFG LED:
•
OS: The active firmware version is differenteither at the local, local redundant,
remote, or remote redundant unit.
•
OLIM type: The local and remote OLIM types are not compatible.
•
OLIM slot: A known invalid card is inserted in the OLIM slot.
•
ELIM type: The local and local redundant ELIM types are not compatible for
redundancy.
•
ELIM slot: A known invalid card is inserted in the ELIM slot.
•
Redundancy: The local and remote modems are not compatible for redundancy, one
modem is redundant and the other is not.
•
Fiber line: The fiber cable is not properly installed (i.e. cable is not properly
connected from local Tx connector to remote Rx connector, or cable is not
properly connected (primary connected to secondary instead of primary).
•
Setup: All the online modems have discrepancies, for example: modem rate,
loopback control mode, line coding, framing, or switch over mode.
•
Fiber path: Crossed fiber optic paths in a redundant configuration.
•
Main: Main module mismatch.
•
Composite: Composite is looped back to itself and is reading its own IMDL address.
