Color/Activity

Description

 

 

 

LINK

Green

• A signal is detected.

 

 

• There is RX synchronization.

 

 

• The GBIC or SFP module is inserted and has no fault conditions.

 

 

• The line card is connected to another functioning Gigabit Ethernet interface

 

 

and has received comma-detect characters.

 

 

 

 

Off

• Loss of signal (LOS). Occurs when the signal is lost at the optical input. For

 

 

example, removing a GBIC or SFP or removing a cable causes both an LOS

 

 

and a loss of synchronization.

 

 

• Loss of RX synchronization. Occurs when the receiver cannot detect

 

 

commas. For example, removing the local RX cable or the remote TX cable

 

 

will cause loss of synchronization.

 

 

• Invalid word received. To maintain receiver alignment and synchronization,

 

 

the receiver looks for a unique detectable code-bit pattern. An invalid word

 

 

condition occurs because the receiver detects an incorrect or unsupported

 

 

character or sequence of characters, resulting in a loss of synchronization

 

 

and a link down condition.

 

 

 

ACTIVE

Green

• When the line protocol is up. For example, you enter a no shutdown

 

 

command as part of the interface configuration.

 

 

• During the line card hardware initialization sequence.

 

 

 

 

Off

• The line is down because of a link failure or problem with the GBIC or SFP

 

 

module.

 

 

• Hardware initialization fails.

 

 

• The line card interface is shut down, because a GBIC or SFP module was

 

 

removed and replaced or was administratively shut down. Note that a newly

 

 

inserted line card is designated administratively down, so the Active LED for

 

 

the interface remains off until the interface is configured. The Active LED on

 

 

the line card does not go on until you configure the line card interface (or turn

 

 

the interface on if it was shut down). As an operational check, you can verify

 

 

that the card is receiving power by looking at the alphanumeric display

 

 

LEDs, which go on when a line card is inserted correctly into the chassis and

 

 

is powered on.

 

 

 

RX FRAME

Green

Packets are being received on this interface.

 

 

 

 

Off

Packets are not being received on this interface.

 

 

 

Alphanumeric LEDs

Ethernet line cards have two four-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display a sequence of messages indicating the state of the card. In general, the LEDs do not turn on until the RP recognizes and powers up the card. As it boots, the line card displays a sequence of messages similar to those in Table 18.

Note It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in Table 18 and Table 19 may not appear on your line card.
