Verifying and Troubleshooting Line Card Installation
Status LEDs
Each 4-port ISE ATM line card provides the following two types of LEDs (see Figure 5) for monitoring
the operating status of the line card:
• Status LEDs – 3 lines grouped next to each port on the line card:
–
Active
–
Carrier
–
RX Cell
• Display (alphanumeric) LEDs – 2 lines, 4-digit alphanumeric (see the “Alphanumeric LEDs”
section on page 27).
The status LEDs are described in Table 10.
The RX Cell LED flashes when data is being received.
The status LEDs on the line card might not go on until you configure 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 Interfaces” section
on page 32).
Alphanumeric LEDs
ATM 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 11.
Note It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in
Table 11 and Table 12 may not appear on your line card.
