Installing Hardware for the G700 Media Gateway and S8300 Media Server
Installation and Cabling
98 Installation and Upgrades for G700 and S8300
December 2003
5 Verify that:
— media modules: all LEDs are extinguished.
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.
— 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 is illuminated 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 be illuminated because the
license file for the S8300 has not yet been installed.
Check and Connect DC Power
NOTE:
The AC/DC version of the G700 will be available 1st-Quarter 2004.
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.
4 Connect the DC feed cable for each G700 to the G700 chassis.
5 Connect the DC feed cable for each G700 to the DC power source.
a Connect the red insulated 10 AWG lead to the -48Vdc Return (positive) source.
b Connect the black insulated 10 AWG lead to the -48Vdc (negative) source.
