Monitoring the SIB Status
To monitor the SIB status:
- Displaying the SIB Summary Status
- Displaying the SIB LED Status at the Command Line
- Check the SIB LED Status on the Faceplate
- Displaying the SIB Environmental Status
Displaying the SIB Summary Status
Purpose
To obtain the SIB summary status.
Action
To display the SIB summary status, use the following command:
Sample Output
t640@host> show chassis sibs Slot State Uptime 0 Spare 1 Online 4 hours, 5 minutes, 47 seconds 2 Online 4 hours, 5 minutes, 42 seconds 3 Online 4 hours, 5 minutes, 37 seconds 4 Online 4 hours, 5 minutes, 33 seconds
Meaning
The command output displays the SIB slot number: 0, 1, 2, 3, and 4. The output also displays the operating status of each SIB as Online, Offline, or Empty, and how long each SIB has been online.
Displaying the SIB LED Status at the Command Line
Purpose
To obtain the SIB LED status at the CLI.
Action
To display the SIB LED status, use the following command:
Sample Output
t640@host> show chassis craft-interface [...Output truncated...] SIB LEDs: SIB 0 1 2 3 4 -------------------------- Red . . . . . Green * * * * *
Meaning
The command output is for a T640 router. Asterisks (*) represent the operating state. The status colors represent the possible SIB operating states: Red (Fail) and Green (OK). All SIBs are functioning normally.
Check the SIB LED Status on the Faceplate
Purpose
To check the SIB LED status on the faceplate.
Action
To check the SIB LED status, remove the component cover and look on the SIB faceplate at the back of the T320 router and the T640 router.
Table 1 describes the SIB LED states.
Table 1: SIB LEDs
Label | Color | State | Description |
|---|---|---|---|
OK | Green | On steadily | SIB is functioning normally |
Blinking | SIB is starting up. | ||
FAIL | Amber | On steadily | SIB has failed. |
ACTIVE | Green | On steadily | SIB is in active mode. |
Displaying the SIB Environmental Status
Purpose
To display the SIB environmental status.
Action
To display the SIB environmental information, use the following command:
Sample Output
T640@host>show chassis environmentClass Item Status Measurement
Temp PEM 0 Absent
PEM 1 OK 32 degrees C / 89 degrees F
SCG 0 OK 37 degrees C / 98 degrees F
SCG 1 Absent
Routing Engine 0 OK 35 degrees C / 95 degrees F
Routing Engine 1 Absent
CB 0 OK 36 degrees C / 96 degrees F
SIB 0 OK 44 degrees C / 111 degrees F
SIB 1 OK 50 degrees C / 122 degrees F
SIB 2 OK 50 degrees C / 122 degrees F
SIB 3 OK 50 degrees C / 122 degrees F
SIB 4 OK 52 degrees C / 125 degrees F
[...Output truncated...]Meaning
The command output displays each component installed in the router, including the operating status and temperature.
If there is a problem with the SIB status, you can display more detailed environmental information with the following command:
user@host> show chassis environment sib

SIB 4 status:
[...Output truncated...]The command output displays the SIB slot, status, and temperature of the air flowing past the SPP card and the power supply voltages.
You can display the environmental status of a particular SIB with the following command:
