The power controllers connect to an AC wall outlet. Each controller has a main
power switch and 10 outlets for system drawers, StorageWorks shelves, and fan tray.
When connecting system components to the controllers, note that system drawer
power cables are gray; StorageWorks shelf power cables and fan tray power cables
are gray. Configuration rules are:
•
A system drawer contains one to three power supplies; each power supply has
one power cable that connects to a power controller.
•
A StorageWorks shelf has one power cable; a shelf equipped with a redundant
power supply has two power cables.
•
Connect all system drawer power cables to the same AC power controller.
•
If a cabinet has three system drawers, connect the power cables as shown in
Figure 1–8.
