AT-SBx3112 Chassis
Note
The AT-SBx3112 Chassis is a 7RU unit. It has slots for ten Ethernet line
cards, two control cards, two system power supply modules, and two PoE
power supply modules. The chassis components are identified in Figure 6
here and Figure 7 on page 24.

Do not remove the shipping brace from the front of the chassis until
after the unit is installed in the equipment rack. You might bend the
chassis and cause misalignment of the slots and card guides if you
lift the chassis into the equipment rack without the shipping brace.

The chassis has slots for ten Ethernet line cards and two AT-SBx31CFC
Central Fabric Controller cards. The slot definitions are predefined and
may not be changed. Figure 9 identifies the slots, which are numbered
starting with 0.
Figure 9. Slots for the Ethernet Line and Control Cards
Slots 0 to 3 and 6 to 11 are for the Ethernet line cards. The cards may be
installed in any order or variety in the slots.
Power Supply
Slots 4 and 5 are for the AT-SBx31CFC Central Fabric Controller card, of
which there must be at least one in the chassis. You may add a second
controller to add redundancy or to increase the available traffic bandwidth
of the chassis.
The chassis has four power supply slots, labelled A to D, across the top of
Slots
the front of the chassis.
Figure 10. Power Supply Slots
25
Chapter 1: Overview
Note
The two right hand slots are for the AT-SBxPWRSYS1 Power Supply,
which supplies power to the Ethernet line cards, control modules, and fan
module. The only chassis component not powered by the module is the
PoE feature on the twisted pair ports of the AT-SBx31GP24 PoE Line
Card.
There are AC and DC versions of the AT-SBxPWRSYS1 Power Supply.
Refer to Figure 4 on page 21 for illustrations of the modules.
A single AT-SBxPWRSYS1 Power Supply can support a fully populated
chassis. However, you may install two power supplies to add power
redundancy to the unit.
The two left hand slots are for the AT-SBxPWRPOE1 Power Supply. This
unit provides PoE for the ports on the AT-SBx31GP24 Line Card. (It
should be noted that the line card also needs the AT-SBxPWRSYS1
Power Supply to operate its switching functions.) You may install two ATSBxPWRPOE1 Power Supplies in the chassis to increase the amount of
available PoE power.
The AT-SBxPWRSYS1 DC Power Supply is not compatible with the
AT-SBxPWRSYS1 AC or AT-SBxPWRPOE1 AC Power Supply.
You should not operate the chassis with both AC and DC power
supplies. You may, however, operate the chassis for a short period
of time with AC and DC power supplies if you are converting it from
one type of power supply to another, such as from AC to DC. This
allows you to transition the chassis without having to power it off.
