SwitchBlade x3112 Installation Guide

61

The SwitchBlade x3112 can host up to four power supplies consisting of 
two AT-SBx3161 System Power Supplies and two AT-SBx3165 PoE 
Power Supplies. The AT-SBx3112 Chassis comes with three blank power 
supply panels in chassis slots A, B, and C as displayed in Figure 33. Slot 
D is left open for the installation of the first AT-SBx3161 System Power 
Supply. Keep the blank power supply panels in place on the unused slots 
to insure proper chassis airflow.

To install the AT-SBx3161 power supply, perform the following procedure:

1. Choose a slot in the chassis for the AT-SBx3161 System Power 

Supply. You can install the system power supply in either slot C or D. If 
this is the initial installation of the chassis, Allied Telesis recommends 
slot D because it does not have a blank power supply panel installed.

2. If you want to install the power supply in slot C, remove the blank 

power supply panel by lifting the blank panel handle and lifting the 
panel out of the slot.

If you are installing one power supply and choose slot C, then install 
the blank power supply panel that came from slot C and install it in 
slot D to insure proper chassis airflow. Close the handle to secure it 
in to the chassis.

Warning
The AT-SBx3161 System Power Supply contains active electronic 
devices, which can be damaged by electro-static discharges (ESD). 
Follow the procedure given in “Protection Against Electrostatic 
Discharge (ESD)” on page 60 to guard against ESD damage when 
unpacking and installing these power supplies.
