Verifying and Troubleshooting the Line Card Installation
If one of these conditions is not met, refer to the “Advanced Line Card Troubleshooting” section on
page 56 to identify any possible problems.
Status LEDs
After installing the line card and connecting the interface cables, verify that the line card is working
properly by checking the following LEDs on the faceplate:
• Interface status LEDs show the status of each fiber-optic connector. Channelized line cards with
optic interfaces can contain some or all of the following status LEDs (see Figure 1, Figure 2,
Figure 3, Figure 4, Figure 5, and Figure 6 for your particular model):
– Active—Indicates the active condition of this port
– Carrier—Indicates the status of SONET framing reception on this port
– RX PKT—Indicates that data is being received on this port
Line cards with T3 ports contain a single status LED (see Figure 7, Figure 8, and Figure 9 for your
particular model):
• Alphanumeric LEDs. Two four-digit alphanumeric LEDs display messages that explain the state of
the line card. (See the “Alphanumeric LEDs” section on page 35.)
The status LEDs might not go on until after you have configured the line card interfaces (or turned them
on, if they were shut down). To verify correct operation of each interface, complete the configuration
procedures for the line card. (See the “Configuring and Troubleshooting Line Card Interfaces” section
on page 40.)

1-Port Channelized OC-12/STM-4 (DS1/E1) ISE Line Card LEDs
See Figure 1 for the location of the LEDs on the 1-port channelized OC-12/STM-4 (DS1/E1) ISE line
card. The different operating states of the status LEDs are shown in Table 13.
