270 Maintenance of the Avaya G350 Media Gateway
June 2004
The S8300 Media Server has a total of 4 LEDs on the faceplate ( Figure 19, S8300 Media Server, on page
269), the three standard LEDs and one additional LED:
— A fourth LED labeled “OK-to-Remove”, which indicates when the S8300’s disk is
properly shut down.
GREEN “OK-to-Remove” LED
The S8300 has a hard drive that must be shut down prior to removal of the S8300. Initiate a shutdown
process by first depressing the shutdown button located next to the fourth GREEN “Ok-to-Remove” LED
for 2-4 seconds (specific to the S8300). The behavior of the S8300’s LEDs during shutdown differs
depending on the version of Communication Manager running:
— For Communication Manager versions 1.2 and earlier, the fourth GREEN LED flashes at a
constant rate until it finally glows steadily.
— For Communication Manager version 1.3 and later, the fourth GREEN “Ok-to-Remove”
LED flashes at a constant rate, and the TST LED flashes slowly at first. As computer
processes exit, the TST LED flashes faster. When the shutdown has completed, the TS
LED goes out, and the “OK-to-Remove” LED then glows steadily.
Once steady, the GREEN LED indicates that the disk drive has been shut down properly and the S8300 is
ready to be removed. Follow standard Media Module removal procedures after the GREEN LED
indicates that the disk drive has been properly parked.
There are three different ways that you can properly shut down the S8300 before it is removed:
— Press the shutdown button on the faceplate for 2-4 seconds.
— Initiate shutdown via the Web interface with a computer connected either:
•
Remotely, on the customer’s LAN
•
Locally, on the S8300 using the Services Port on the faceplate of the S8300
S8300 LED differences from Media Modules
Certain behaviors of the traditional S8300 LEDs differ from the Media Modules because the S8300 is a
Media Server running Communication Manager.
— Situations like “insanity” and IP concepts of “registered” via H.248 do not necessarily
apply to other Media Modules.
— The RED LED provides a major alarm indication. Software turns off the RED LED during
system startup. After startup, software turns on the RED LED whenever a major alarm is
present, and turns off the RED LED whenever a major alarm clears. Since the S8300 sees
a major alarm whenever an Avaya G350 Media Gateway becomes unregistered, this
means the RED LED turns on. If the Media Gateway subsequently becomes registered,
the major alarm clears, and the RED LED turns off.
NOTE:
For an S8300 configured as an LSP, the converse is true. If an Avaya G350 Media
Gateway registers with an LSP, a major alarm is generated, and the RED LED turns on.
When the Media Gateway unregisters, the RED LED turns off.
