turning off a lefthand p4300

I have a customer with a HP lefthand p4300 firmware 8.5.
this lefthand has 2 additional enclosures with disks.
i want to turn it off, but  i am not sure if i turn shelve 3, shelve 2 and p4300 off. or do i just turn p4300 off and then shelves 2 and 3.

thanks.

Main system is always first, then expansion units.
Power-on is the opposite - expansion first, then main.

(This is true for all RAID systems with expansion units)

Well, back up a minute.

The preferred method is to do a shutdown through the GUI management utility.

If that's not accessible for some reason, then as dlethe says, power down the node first -- a single tap on the power button should cause a gentle shutdown on a P4300 -- and then any attached storage.

Well, should have said that .. it is a given you shut down the system through the GUI, and dismount/flush any mounted filesystems from host ... I was addressing power off/on.
