When there are a full set of SFMs online, powering down one SFM will reduce the total bandwidth
supported by the chassis, and may affect data flow. A warning message is issued at the command line that
requires user confirmation to proceed with the command (Figure 63-5)
Figure 63-5. Command Example: power-off sfm with data traffic warning message
Since this command is for diagnostic purposes, you can power off more than one SFM which may cause a
switch fabric module to go down. A warning message is issued at the command line and requires user
confirmation to proceed with the command (Figure 63-6)
Figure 63-6. Warning Message: power-off sfm command with switch fabric down
Once the SFM is powered off, the SFM status indicates that the SFM has been powered off by the user. Use
the
show sfm all command to display the status (Figure 63-7).
Figure 63-7. Command Example: show sfm all
Note: Execute this command only during an offline diagnostics; this command may bring down the switch
fabric.
