Chapter 3 Installing the IGX
Initial Startup of the IGX
Step 3 Wait for the power-up diagnostic to run.
Step 4 If the NPM fails the power-up diagnostics again, replace it with a known-good NPM. For card
replacement procedures, refer to Chapter 4, “Troubleshooting the IGX.”.
Card Self-Test
IGX software includes internal diagnostic routines that periodically test a card’s performance. The
diagnostics automatically run in background and do not disrupt normal traffic. If a failure occurs during
the test, the red FAIL LED comes on. You can also view status on a terminal with the dspcd command.
The report of a card failure remains until cleared. On the CLI, clear a card failure by using the resetcd
command. Two types of resets exist. The reset-failure clears the event log of failures detected by the
test. It does not disrupt operation. A reset-hardware resets the card’s firmware: it reboots the firmware
(momentarily disabling the card) and, if a redundant card exists, switches over to the standby card.
Inspecting Status Lights
Check the status lights on the system unit cards. Table 3-4 shows the lights for normal status where n+1
redundancy exists for NTM and CVM cards.
• If any card’s FAIL light is on steady, or if there is no ACTIVE card when there should be for that
type, try removing and inserting the same card. Also, check the EEPROMs on the card to make sure
that they are all seated properly (press down on the ICs to ensure proper seating).
• If a power supply AC okay LED or DC okay LED is off, try removing and inserting the power
supply. If any LED remains off, see Chapter 4, “Troubleshooting the IGX.”
