Chapter 2 Cisco IGX 8400 Series Cards
Service Modules
Card Self-Test
Diagnostic routines periodically run to test the card's performance. These diagnostics run in the
background and do not disrupt normal behavior. If a failure is detected during the self-test, the faceplate
red fail LED turns on. In addition, you can check the status of the card by using the switch software
dspcd command. If a card failure is reported, the report remains until cleared. To clear a card failure,
use the switch software resetcd command.
There are two types of resets: hardware and failure. The reset failure clears the event log of any failure
detected by the card self-test and does not disrupt card operation. The hardware reset reboots the
firmware and resets the card, which momentarily disables the card.
Service Modules
Service modules allow configuring of data, voice, ATM, Frame Relay (FR), and IP services over the
IGX node. In an operational network, multiple service cards may be installed in the same physical
chassis, with many different possible configurations of service types, interface connector types, and
transmission formats. These service modules can be used in any of the three chassis models. However,
careful planning of slot space and cabling is important for easy and efficient maintenance and
troubleshooting tasks.
Standard Service Module LEDs
IGX service front cards and back cards have several standard indicator LEDs on their faceplates. While
some cards may have additional LEDs, all cards have both a green active LED and a red fail LED located
at the bottom of the faceplate.

LED Status Meaning
Fail Steady An error has occurred. For information on troubleshooting the card,
refer to the card information listed later in this chapter.
Fail Blinking The back card is missing or has not been installed.
Active Steady The card is active and is carrying traffic or processing data.
Active Blinking The card is executing a card self-test.
Both LEDs Off The card is either redundant and in standby, or the card is not in use.
Both LEDs On The card has failed but remains in active state because no redundant card
is available. May also indicate specific failures in the card’s lines—refer
to the card’s troubleshooting information later in this chapter.
