Verifying and Troubleshooting the Line Card Installation
1-Port Channelized OC-48/STM-16 ISE Line Card LEDs
See Figure 2 for the location of the LEDs on the 1-port channelized OC-48/STM-16 ISE line card. The
different operating states of the status LEDs are shown in Table 14.
4-Port Channelized OC-12/STM-4 ISE Line Card LEDs
See Figure 3 for the location of the LEDs on the 4-port channelized OC-12/STM-4 ISE line card. The
different operating states of the status LEDs are shown in Table 15.
Table 13 1-Port Channelized OC-12/STM-4 (DS1/E1) ISE Line Card Status LED Descriptions
LED Color/Activity Description
ACTIVE
Green • A signal is detected.
• There is RX synchronization.
Off
• The line card is administratively down.
• The line card is in diagnostics mode.
• Loss of RX synchronization. For example, removing the
local TX cable or the remote RX cable can cause loss of
synchronization.
CARRIER
Green • Framing is present.
• 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 card is waiting to receive framing.
• A local alarm has occurred.
• Hardware initialization fails.
• The line card interface is administratively down.
RX PKT
Green Packets are being received on this interface.
Off Packets are not being received on this interface.
Table 14 1-Port Channelized OC-48/STM-16 ISE Line Card Status LED Descriptions
LED Color/Activity Description
ACTIVE
Off
Solid green
Port is administratively down, or diagnostics are running.
Port is administratively up.
CARRIER
1
Off
Solid green
Port is up, but is detecting local alarm or is waiting for receive
framing.
Port is up, and receive framing was found.
RX PKT
Blinking green Line card is receiving data.
1. Only Section and Line alarms in SONET operation (or regenerator section [RS] or multiplex section [MS] alarms in SDH)
affect the Carrier LED; path alarms (higher and lower) are ignored.
