Installing A Power Supply - Allied Telesis AT-8400 Series Reference Manual

Installing a Power Supply

This section contains the procedure for installing an AC or DC power
supply in an AT-8400 Series switch. You can install a power supply
without powering off the chassis.
Before installing a power supply, please note the following:
❑ An AT-8400 Series switch will have either AC power sockets or DC
terminal blocks on the back panel. You should check that the new
power supply is appropriate for your system. For example, you
cannot install an AT-PWR10 (AC) power supply in a DC chassis or
an AT-PWR11 (DC) power unit in an AC chassis.
❑ There are several different models of AC and DC power supplies.
Each model is rated for a different power load. Both power
supplies in a chassis must be of the same model type. Do not mix
power supplies with different power ratings in the same chassis.
Note
If you are replacing a power supply and are continuing on from the
procedure Removing a Power Supply
To install a power supply, follow these steps:
1. Using a Phillips screwdriver, loosen the two captive screws that
secure the power supply cover to the chassis and remove the cover.
You remove the cover by angling it from the bottom as you slide it
down and out of the chassis.
