Cisco CX-AIP-TM Installation And Configuration Manual page 31

AIP LEDs function as follows:
•
Enabled—When on, this LED indicates that the AIP is enabled for operation; however, the
interface ports might not be functional or enabled.
•
RX cells —When on, indicates that the AIP has received an ATM cell. This LED will flicker in
normal operation, indicating traffic.
•
RX carrier —When on, indicates that the AIP has detected carrier on the RX cable. For a
fiber-optic interface, this means simply that light is detected.
After you connect cables to the AIP, observe the LED states and the console display as the router
initializes. When the system has reinitialized all interfaces, the enabled LED on the AIP should go
on. The console screen will also display a message as the system discovers each interface during its
reinitialization. After system initialization, the enabled LED goes on to indicate that the AIP is
enabled for operation.
The following conditions must be met before the AIP is enabled:
•
The AIP is correctly connected to the backplane and receiving power.
•
The system bus recognizes the AIP.
•
A valid version of AIP microcode is loaded and running.
If any one of these conditions is not met, the enabled LED does not go on.
Verify that the AIP is connected correctly as follows:
Step 1 While the system reinitializes each interface, observe the console display messages and
verify that the system discovers the AIP. The system should recognize the ATM interface
but leave the interface configured as down.
When the reinitialization is complete, verify that the enabled LED on the AIP is on and
Step 2
remains on. If the LED does stay on, proceed to Step 5. If the enabled LED does not stay
on, proceed to the next step.
Step 3 If the enabled LED on the AIP fails to go on, suspect the that the AIP board connector is
not fully seated in the backplane. Loosen the captive installation screws, then firmly push
the top ejector down while pushing the bottom ejector up until both are parallel to the AIP
faceplate. Tighten the captive installation screws. After the system reinitializes the
interfaces, the enabled LED on the AIP should go on. If the enabled LED goes on,
proceed to Step 5. If the enabled LED does not go on, proceed to the next step.
If the enabled LED still fails to go on, remove the AIP and try installing the AIP in another
Step 4
available interface processor slot.
•
If the enabled LED goes on when the AIP is installed in the new slot, suspect a failed
backplane port in the original interface processor slot.
•
If the enabled LED still fails to go on, but other LEDs on the AIP go on to indicate
activity, proceed to Step 5 to resume the installation checkout and suspect that the
enabled LED on the AIP has failed.
•
If no LEDs on the AIP go on, suspect that the AIP is faulty.
•
If the enabled LED still does not go on, do not proceed with the installation. Contact
a service representative to report the faulty equipment and obtain further instructions.
