Media Module Maintenance; Hot Swap; Leds - Avaya G350 Maintenance Manual

Media Module maintenance

Procedures for maintenance of Media Modules vary with the type of Media Module being maintained.
Data Media Modules, such as the MM314, MM340, and MM342, are administered locally. Voice Media
Modules are administered from the server, using Communication Manager. Maintenance for each Media
Module is very similar to that for its respective DEFINITY server circuit pack counterpart. Field
replacement of Media Modules can be performed in many cases without removing power to the G350
(hot swapping).

Hot swap

The following Avaya Media Modules are hot swappable:
•
DCP Media Modules (MM312, MM712)
•
Analog Trunk/Telephone Port Media Module (MM711, MM714)
•
T1/E1 Media Module (MM710)
•
BRI Media Module (MM720, MM722)
For procedures on adding, removing, or replacing Media Modules, refer to
on page 35.
CAUTION:
The S8300 Media Server is NOT hot swappable and can reset the entire G350 upon
insertion or removal, as well as resetting each G350 that is currently registered with it.
When removing the S8300, initiate a shutdown process by first depressing the Shut Down
button (for 2 seconds) located next to the fourth LED, labelled "Ok-to-Remove" (specific
to the S8300). This LED will first blink; then go steady. Once steady, this GREEN LED
indicates that the disk drive has been shut down properly and is ready to be removed. If
you remove the S8300 before the disk is shut down, you may corrupt important data. See
Replacing the S8300 Media Server
NOTE:
The S8300 Media Server can be a primary server for a network of IP endpoints and Avaya
G350 Media Gateways, or it can be configured as a Local Survivable Processor (LSP), to
become active only if connectivity to the primary server is lost. Most of the material in this
book applies to the S8300 Media Server configuration; only a few parts apply to the LSP
configuration.

LEDs

The general use of LEDs is to give a quick overall understanding of the health of the system and
subsystems. When alarms or problems occur, LEDs indicate that attention by a technician is needed.
LEDs are not suitable for conveying detailed diagnostic information. Further diagnosis or
troubleshooting is supported by software-based solutions that can provide detailed text explaining the
error condition. Troubleshooting and diagnostic tasks can be supported by software accessed by laptops
in the field or remotely from an administrator's computer.
