9.2 .edge - Replacing a Power Supply Unit
The following procedure can be used to exchange an AC power supply unit.
The same procedure can be used to exchange a DC power supply unit, except that you must remove and replace the cable
strain relief and observe all of the DC power supply conditions (described earlier).
Overview
Each .edge frame is powered by two power supplies (fitted to the front). Only one PSU is required for operation; the second
provides redundancy.
The power supplies are hot-pluggable and so it is possible to replace the redundant unit while the frame is powered.
What you will need
No tools are required - as the PSU is unlocked using the release lever.
1 x .edge AC power supply - identical to the other PSU in the frame*.
*It is important that the frame is fitted with two identical power supplies: of the same type and from the same manufacturer.
The permitted options are explained in
.edge - Power Supplies .
