Troubleshooting the SIP
If a SIP fails to operate or to power up upon installation:
- Make sure that the SIP is seated firmly in the line card chassis slot. One easy way to verify physical installation is to see whether the front faceplate of the SIP is even with the fronts of the other line cards installed in the card cage.
- Check whether the ejector levers are latched and that the captive screws are fastened properly. If you are uncertain, unlatch the levers, loosen the screws, and attempt to reseat the SIP.
- Determine whether there are any active alarms by looking at the alarm LEDs on the route processor.
- Examine the power distribution units (PDUs) to see whether the chassis, as a whole, is receiving power.
- Use the LED on the SIP to verify the correct installation and operation of the card. The STATUS LED indicates whether the card is properly seated and operating correctly:
- Green—The card is properly installed and operating correctly.
- Amber—The card is properly installed, is powered, and IOS XR is loading.
- Off (dark)—Verify that the card is installed correctly. Also verify that there is power to the card by looking at the indicators on the power shelf (10-slot) or PDU (6-slot).
