Note: Execute this command only during an offline diagnostics; this command may bring down the switch
fabric.
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

SFM0 is active. Powering it off it might impact the data traffic.

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
