Interface Processor Leds; Aip Leds - Cisco 7000 Series Hardware Installation And Maintenance Manual

Interface Processor LEDs

Each interface processor (except the RP, which is not really an interface processor) contains an
enabled LED. When on, this LED indicates that the interface processor is operational and that it is
powered up. It does not necessarily mean that the interface ports are functional or enabled. The
following sections describe the LEDs for each interface processor. The SP has no LEDs other than
the enabled LED to indicate that it is operational.

AIP LEDs

The three LEDs above the ATM port (see Figure B-4) indicate the following:
•
Enabled—When on, 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.

CIP LEDs
Following are the functions of the CIP LEDs. (See Figure B-5.)
•
Enabled—Indicates that the CIP has been enabled for operation by the system.
•
Present—Indicates that the adapter (ECA or PCA) has been detected by the CIP.
•
Loaded—Indicates that the adapter (ECA or PCA) firmware has been completely loaded.
•
Signal—For the ECA, this LED indicates that the Sync signal has been detected.
For the PCA, this LED indicates that the Operational Out signal has been detected. Note that even
though a system reset and selective reset both cause the Operational Out signal to drop, the signal
LED will still be on during those sequences.
