Powering On The Controller Module And System; Figure 3-1 Controller Module Power Switches - Sun Microsystems Sun StorEdge A3500 Manual

3.1 Powering On the Controller Module
and System
Note – The power cords from the controller module and drive trays should be
connected into the expansion cabinet power sequencers so that the drive trays
receive power first, and the controller module receives power last.
If you received a factory configured Sun StorEdge A3500/A3500FC system, the
power cords are already set up for this power-on sequence. If you installed a new (or
upgrade) controller module into an existing cabinet, see Chapter 2 for power cabling
instructions.
1. Prepare to power on the Sun StorEdge A3500/A3500FC system as follows:
a. Make sure that all the controller module canisters are connected and locked
into place properly.
b. Make sure that all power and SCSI or fibre optic cables are attached securely.
2. Turn all power switches on the drive trays to the On position.
Refer to your drive tray documentation for power switch location.
3. Turn both power switches at the rear of the controller module to the On position
(
