Installing and Replacing AT-PWR06 Power Supply Module
The AT-PWR06 power supply module may be installed in one of the two 
power supply slots - PSU1 and PSU2. See Figure 1 on page 19 for the 
location of these slots.
The AT-DC2552XS L2 Data Center Switch can operate under full load 
with one power supply module installed. However, if you want power 
supply redundancy, a second power supply may be installed.
There is no functional difference between the two available power supply 
slots. Operation of the AT-DC2552XS is the same when installed in either 
slot. If you want to use only one power supply, Allied Telesis recommends 
that you install it in the PSU1 slot.
The following procedures are included in this section:
