Installing the AT-SBxPWRSYS1 AC System Power Supply
For background information on the AT-SBxPWRSYS1 AC Power Supply,
refer to “Power Supplies” on page 27. The chassis must have at least one
AT-SBxPWRSYS1 AC or DC Power Supply.
Warning
The electronic components in the AT-SBxPWRSYS1 AC Power
Supply can be damaged by electro-static discharges (ESD). Follow
the procedure in “Protecting Against Electrostatic Discharge (ESD)”
on page 106 to guard against ESD damage when unpacking and
installing the power supply.
To install the AT-SBxPWRSYS1 AC Power Supply, perform the following
procedure:
1. Choose a slot for the AT-SBxPWRSYS1 AC Power Supply in the
chassis.
You may install it in either slot C or D, shown in Figure 47. The first AT-
SBxPWRSYS1 AC Power Supply should be installed in slot D,
because the slot does not have a blank power supply panel.
Figure 47. Power Supply Slots
Caution
The AT-SBxPWRSYS1 AC Power Supply will not work in slot A or B.
2. If the chassis already has a power supply in slot D, remove the blank
power supply panel from slot C by lifting the blank panel handle and
sliding it out of the slot, as shown in Figure 48 on page 108.
