Power Cycling the Subsystem
To power cycle a RAID subsystem means to:
• Shut down
• Turn off the power
• Turn on the power
•Restart
Power cycling is sometimes required as a remedial action but only when
prompted by a message from software or when directed by Technical Support.
To power cycle the RAID subsystem:
1. Shut down the subsystem.
See “Shutting Down the Subsystem” on page 67 or page 233.
When the controller shuts down, your network connection is lost.
2. Manually turn OFF the switches on both power supplies of the RAID
subsystem and all attached JBOD expansion units.
3. Wait at least 10 seconds.
4. Manually turn ON the switches on both power supplies of the JBOD units.
5. Manually turn ON the switches on both power supplies of the RAID
subsystem.
6. Wait no less than two minutes.
7. Do one of the following actions:
• Open your browser and log into WebPAM PROe.
• Re-establish your Telnet or SSH connection to the subsystem and open
the CLU.
If you cannot log in immediately, wait 30 seconds and try again.
Important
If your RAID subsystem manages JBOD expansion units, always
power on the JBOD expansion units first. Then power on the RAID
subsystem.
