Fsip Leds - Cisco 7000 Series Hardware Installation And Maintenance Manual

Interface Processor LEDs
LED Pattern
1. For the LED patterns, "–" means off, "O" means on, and "X" means does not apply.

FSIP LEDs

The FSIP LEDs are shown in Figure B-10. As with the other interface processors, the enabled LED
goes on when the FSIP is enabled for operation. However, unlike the LED cluster on other interface
processors, the LEDs for each serial port are adjacent to the connector. Table B-2 lists descriptions
of each LED.
Figure B-10
The conn (connected) LED goes on when the interface is connected to the network. During normal
operation, the three other LEDs go on to indicate data and timing signal traffic, or an idle pattern that
is commonly sent across the line during idle time.
