SFM Power Commands
SFMs in a chassis are in one of three power states:
•
Power on
. The SFM is up and running as one of the components of the switch fabric.
•
Power off
. The SFM is down and not participating in the switch fabric, nor will it takeover in the event
that one of the powered on switches fails.
•
Standby
. The SFM is up, but is waiting as a redundant SFM in case of the failure of one of the other
SFMs.
The normal state of an SFM is power on, and at least four powered SFMs are necessary for the
OmniSwitch 8800 to function. If a fifth SFM is installed, it is possible to change the power state of any of
the SFMs in the chassis.
Powering On an SFM
To change the state of an SFM to power on, enter the
command with the SFM slot number,
as shown:
-> power fabric 4
The SFM in slot 4 of the chassis would now power up. The SFM slot numbers and status can be viewed
using the
command.
The
power fabric
command is only valid when their are five SFMs in a chassis (four running and one
redundant).
Powering Off an SFM
To change the state of an SFM to power off, enter the
command with the SFM slot number
and the
no
keyword, as shown:
-> no power fabric 4
The SFM in slot 4 of the chassis would now power down. The SFM slot numbers and status can be viewed
using the
command.
The
power fabric
command is only valid when their are five SFMs in a chassis (four running and one
redundant).
Setting an SFM to Standby
To change the state of an SFM to standby, enter the
command with the SFM slot number,
as shown:
-> fabric standby 4
The SFM in slot 4 of the chassis would now revert to standby mode. In standby mode, this SFM is consid-
ered the redundant SFM and is ready to take the place of another SFM that fails. The SFM slot numbers
and status can be viewed using the
command.
The
fabric standby
command is only valid when their are five SFMs in a chassis (four running and one
redundant).
