Using LEDs to Check ACIP Status
After you install the ACIP and attach the interface cable between the ACIP’s interface port and your cable headend (TeraLink 1000) or external ATM switch, verify the installation by observing the LED states and the console display.
When the system has reinitialized all interfaces, the enabled LED on the ACIP 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, which is present on all interface processors, goes on to indicate that the ACIP is enabled for operation.
The following conditions must be met before the ACIP is enabled:
•
•
•
The ACIP is correctly connected to the backplane and receiving power.
The CyBus recognizes the ACIP card.
A valid version of ACIP microcode is loaded and running.
If any of these conditions is not met, the enabled LED does not go on.
Verify that the ACIP is installed correctly as follows:
Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the ACIP as follows:
•If you installed a new ACIP, the system should recognize the new ATM interface but leave the interface configured as down.
•If you replaced an ACIP, the system should recognize the interface and put the interface into the same state (up or down) the interface had when you removed it.
Step 2 When the reinitialization is complete, verify that the enabled LED on the ACIP is on and 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 ACIP fails to go on, suspect that the ACIP 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 at a
Step 4 If the enabled LED still fails to go on, remove the ACIP and try installing it in another available interface processor slot.
•If the enabled LED goes on when the ACIP 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 ACIP go on to indicate activity, proceed to step 5 to resume the installation checkout and suspect that the enabled LED on the ACIP has failed.
•If no LEDs on the ACIP go on, suspect that the ACIP is faulty.
•If the enabled LED still does not go on, do not proceed with the installation. Contact a customer service representative to report the faulty equipment and obtain further instructions.
Step 5 If the ATM interface is new, proceed to the section “Configuring the ACIP, ” on page 21, to configure the new interface. (The interface is not available until you configure it.)
