Powering On AT-SBxPWRSYS1 or AT-SBxPWRSYS2 AC System
Power Supplies
The procedure in this section explains how to power on AT-SBxPWRSYS1
or AT-SBxPWRSYS2 AC System Power Supplies in slots C and D on the
front panel. If you have not already installed the power supplies, refer to
“Installing AT-SBxPWRSYS1 or AT-SBxPWRSYS2 AC System Power
Supplies” on page 107 for installation instructions.
Note
If the chassis has both system and PoE power supplies, you may
power them on in any order or simultaneously.
Caution
If the chassis has two AT-SBxPWRSYS2 System Power Supplies,
you must power them on within 90 seconds of each other.
Otherwise, the active master controller card might restart its
operating software, which will delay the initialization process of the
chassis.
To power on the AC system power supplies, perform the following
procedure:
1. Identify AC sockets C and D in the recessed panel on the back panel
of the chassis, shown in Figure 105 on page 174. These sockets are
for the AC system power supplies in slots C and D on the front panel of
the chassis.
