Troubleshooting VISM Cards
VISM Card LEDs
The VISM card uses the following three card status LEDs (see Figure 9-6) to indicate certain states:
• ACT—Green indicates the active state.
• STBY—Orange, or blinking orange, indicates one of the following:
– VISM is in the standby state.
– VISM is in the mismatch state.
– VISM card DSPs are currently involved in the VISM card bootup.
• FAIL—Red indicates the failure state, or certain stages of the bootup process.
The VISM card uses eight line status LEDs (see Figure 9-6) to indicate the following states of the eight
T1 or E1 ports on the VISM back card:
• Green—A line has been added and there is no alarm on that line.
• Orange—A line has been added and there is a yellow alarm condition on the line.
• Red—A line has been added and there is one of the following conditions on the line:
– Loss of signal (LOS) (red alarm condition)
– Loss of frame (LOF)
– Alarm indication signal (AIS)
