Reading Network Processor Module LED Indicators

From left to right, when facing the chassis front, the three lower LEDs on the left correspond in
position to the three network processor modules, if present, and represent their status. The upper
LEDs, when blinking, indicate network activity on their respective interfaces.
When on, the bottom LED on the far right indicates that the system card's power is on, and the top
LED on the far right indicates that the processor is working.
Reading Network Processor Module LED Indicators
The network processor module LEDs are all visible through cutouts in the rear of the chassis.

Ethernet Network Processor Module LED Indicators

When facing the rear of the chassis, the LEDs on the dual-port Ethernet network processor module
are labeled as shown in Figure 4-2. (Also see Figure 2-9.)
Figure 4-2
When facing the rear of the chassis, the LEDs on the single-port Ethernet network processor module
are labeled as shown in Figure 4-3. (Also see Figure 2-5.)

AUI—When lit, this indicates the AUI connection is selected. Use the media command to
configure your selection of 10BaseT or AUI. The syntax of the media command follows:
media–type aui | 10BaseT
Details on the media command are in the appropriate IOS software publication.
When AUI is selected, none of the other LEDs on the network processor module will be lit. The
other LEDs are meaningful only when you use 10BaseT, and you have a link.
