Section I: Hardware Overview

AT-SBxPWRSYS1 AC Power Supply

The AT-SBxPWRSYS1 AC Power Supply, shown in Figure 9, is the power
supply unit for the chassis. It supplies power to all the hardware
components in the chassis, except for the PoE feature on the ports on the
AT-SBx81GP24 Line Cards. The PoE feature is powered by the AT-
SBxPWRPOE1 Power Supply.

Figure 9. AT-SBxPWRSYS1 Power Supply

A single AT-SBxPWRSYS1 Power Supply can support a fully populated
chassis, with any combination of Ethernet line cards. The chassis can
have two AT-SBxPWRSYS1 Power Supplies for power redundancy.

Power supply modules are not included with the chassis and must be
purchased separately.

The AT-SBxPWRSYS1 Power Supplies are installed in the two right hand
slots, labeled C and D, at the top of the front of the chassis. If you are
installing just one power supply, you may install it in either slot. The
locations of the slots are shown in Figure 6 on page 25.

The AT-SBxPWRSYS1 Power Supply is hot swappable. If a chassis has
two power supplies and one of them fails, you may replace the failed unit
without having to power off the chassis.
