When you first power up the S8300, the red Major Alarm LED will be lit. During startup,
self-tests will run, after which all LEDs will be off. At this point, you can connect to the
S8300. There will be another flash of LEDs when Communication Manager starts.
5. Verify the following LED’s status:
- On the media modules: all LEDs are off.
Note:
Note:
If the initial administration of all media modules is not completed, an alarm LED
will light.
- The master LED (labeled MSTR) or the system LED (labeled SYS) lights on one and only
one module in the stack.
- On the G700 media gateway, the green CPU LED is illuminated, when both the P330
stack processor (Layer 2 Switching Processor) and the G700 Media Gateway Processor
(MGP) are in a normal operational state.
The red ALM LED lights whenever an alarm exists in the G700 Media Gateway Processor.
The ALM LED might signal either a hardware failure or a software or firmware condition that
could be cleared by resetting the processor. It will also light because the license file for the
S8300 has not yet been installed.
Checking and Connecting DC Power
Note:
Note:
Perform this check procedure only if you are installing a G700 that is using the
DC input-power option rather than AC input-power.
Before you connect the G700 media gateway DC feed cable to the DC power source, check the
DC power source using a KS-20599 digital voltmeter (or equivalent).
To check DC power
1. Verify that the meter reads between -41Vdc and -56 Vdc across the -48Vdc and -48V
Return distribution leads from the DC source.
2. Verify that the meter reads 0V between the -48V Return lead of the DC power source and
the approved ground.
3. If either step 1 or step 2 fails the verification, DO NOT PROCEED with step 4.
Request that a qualified electrician resolve the problem.
