Allied Telesis AT-PWR14 Fascicule

The AT-PWR14, shown in Figure 1, is an AC redundant power supply (RPS) 
used with the AT-CV5000 chassis only. When installed, the module operates 
in a standby mode. If the standard power supply fails or loses power, the AT-
PWR14 module changes from standby to active and provides all power to the 
system to prevent a network failure.

The power supply is hot-swappable. You can install it without powering 
OFF the AT-CV5000 chassis.

Before installing a power supply, please note the following guidelines:

The AT-CV5000 chassis comes with two slots designated for the power 
supplies; however, it is shipped with one standard power supply 
preinstalled and one empty slot for an optional power supply. The 
redundant power supply can be ordered separately from your ATI sales 
representative.

Make sure that both power supplies (primary and redundant) are rated for 
the same power ratings. For information on the power supply module, 
refer to the documentation that is shipped with the module.

The AT-PWR14 power supply can be installed in either one of the power 
supply expansion slots while the converter chassis is powered ON. You 
do not need to power OFF the chassis to install the power supply.
