Removing the failed switch
NOTE:
•
In redundant-switch environments, the 3Gb SAS Switch may
be hot-replaced in an operational enclosure.
•
In single-switch environments, all activity through the switch
must be halted prior to the replacement.
•
The 3Gb SAS Switch does not have a power on/off button.
Power is automatically applied or removed when the switch
is installed or removed from the enclosure. Alternatively, power
can be applied or removed through the Onboard Administrator
application.
For illustration purposes, the following images demonstrate removing a
3Gb SAS BL Switch in interconnect bay 5 of a BladeSystem c7000
enclosure.
1.
Stop all traffic through the failed or failing switch.
2.
Use Onboard Administrator to shut down the switch. (Optional, but
a best practice.)
3.
Disconnect all cables from the failed switch, making sure to label
each cable with its port number to facilitate re-connection.
4.
Remove the failed switch.
