8 Power Supply Modules
The devices of the DMX series can be equipped and operated with two redundant power
supply modules (hot-swap, hot-plug,) and operated. If a power supply module fails, the
second automatically takes over the complete power supply. The operation will continue
without interruption.
Proceed as described in the following to exchange a defective power supply module.
Note that the following descriptions are based on devices with redundant power supply
modules. They equally apply to devices with only one power supply module.
