MGC faceplate errors

mgc faceplate

The following applies to:

The four-character LED faceplate display normally shows the configured superloop and shelf number: LLLS
Note, the shelf digit is a special superscript character to differentiate it from the superloop number.

During power-up/boot:

When an MGC boots, diagnostic information from the hardware and firmware tests appears on the faceplate.
In a normal boot process, the messages appear in the following order: BOOT ➤ POST ➤ PASS ➤ LOAD
If a fatal self-test error occurs, then PASS and LOAD do not appear, instead an error code appears.

MGC faceplate startup codes:

Display Description
BOOT This is the first message when display becomes active
POST Power on self test, appears while the MGC performs hardware system tests during system power up
PASS Power on self test pass
EXXX Error code, where XXX is numeric. Appears if a serious system error is detected - see below
LOAD Application software is loading

After the boot loader loads the CSP and starts to run, the faceplate displays diagnostic information.

During normal operation:

During normal operation, the LED displays the IP Media Gateway (IPMG) superloop and shelf number. If an error occurs the display cycles between the loop/shelf number and the error code. Each item is displayed for 20 seconds.

MGC faceplate normal operation / error codes:

Display Description
LLLS IPMG superloop and shelf number, where LLL is the superloop and S is the shelf. Eg, 0320 or 1201
UNRG MGC is un-registered, this my be due to either a configuration or network error
E001 A 96 port daughter board is installed in DB position 2, this is not supported. Re-install it in position 1
E002 Unable to send registration request to call server
E003 Link down to call server
E004 DSP Daughter board is not registered with call server

Reboot MGC:

To reset/reboot an MGC, press the front panel RST button; or Telnet the cards IP address, press [CTRL] LDB to enter the Local DeBug shell, login (admin2/0000) and enter the command: reboot.

ldb> reboot

The Telnet session will immediately drop, and the card reboots.
