AC power strips connect to an AC input box outlet. The AC input box has a two-
pole main circuit breaker. Each AC power strip has a single-pole thermal circuit
breaker and six outlets for system drawers, StorageWorks shelves, and fan tray. A
maximum of three AC power strips can be used in the cabinet; they are installed in
order of the numbers shown in Figure B–8. When connecting system components to
AC power strips, note that system drawer power cables are black; 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 an AC power strip.
•
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 strip.
•
A second power strip is required if you install more than three StorageWorks
shelves in a cabinet with one system drawer.
•
If a cabinet has four system drawers, connect the fourth system drawer input
power cables to different AC power strips.
