Card Installation and Node Startup 3-47
Initial Startup of the IGX
Step 14
At the back of the unit, turn the circuit breakers to the ON position. In a system using a
DC source, attach the cable guard (AC should already have the cable guard in place).
After initial power up, DC systems can be switched off and on either at the PEM or at the
building site’s resident circuit breaker. Use the building’s DC circuit breaker only if all
cables are clearly marked; if the building’s dedicated circuit breaker has an actual switch
and not just a fuse; and if controlling power at the building’s circuit breaker actually
provides an advantage over removing the cable guard.

Step 15
Observe that, after you turn on the IGX node, the cards run diagnostic self-test:
•
The standby NPM red “FAIL” light flashes until self-testing and configuration updates
are completed. The other NPM immediately becomes active but also performs
self-testing and configuration updating. The process can take several minutes.
are completed. The other NPM immediately becomes active but also performs
self-testing and configuration updating. The process can take several minutes.
•
The remaining cards show “FAIL” for a few seconds then become active or standby.
•
The AC and DC “Okay” LEDs immediately turn on.
•
Alarms might be indicated. Alarms might be present on trunks that have not been
physically connected. The alarms disappears when those trunks are downed.
physically connected. The alarms disappears when those trunks are downed.
Step 16
If an alarm exists for a T1 or an E1 line that is physically connected to the IGX node, try
reconnecting the line to make sure there is a good physical connection. If the alarm
condition continues, a valid T1 or E1 problem might exist.

NPM Startup Diagnostic Test
The IGX software contains a group of diagnostic tests that run on the system’s hardware at power-up.
The startup diagnostic either passes or fails the NPM(s). The test result is displayed on the control
terminal screen as pass or fail. The pass screen looks like this:
The startup diagnostic either passes or fails the NPM(s). The test result is displayed on the control
terminal screen as pass or fail. The pass screen looks like this:

Static RAM test passed.
TDM memory test passed.
Fast RAM test passed.
BRAM test passed.
Dynamic RAM test from Hex Address 400000 to Hex Address 9FFFFF
