MGC four-character LED faceplate display 397

Use of the four-character LED display during MGC boot

When the system boots, the diagnostic information from the hardware and

firmware sanity tests appears on the faceplate. The messages that appear

on the four-character LED display during MGC bootup are shown in the

following table. Further design investigation is required to confirm that all

suggested messages during bootup are possible.

active.

POST

Power on self test message appears while the

MGC performs hardware system tests during

system power up.

In normal operation the messages appear in the following order: BOOT,

Use of the four character LED during MGC normal operation

After the boot loader loads the CSP and starts to run, you can use the

faceplate display for diagnostic information.

During normal operation, the four-character LED displays the superloop

and shelf number of the Media Gateway 1000E (MG 1000E) with MGC.

If an error occurs that requires a diagnostic message to appear, then

the display cycles between displaying the cabinet number and the error

code. Each item appears for 20 seconds. The following table shows the

messages that appear.
