Replacing Power Supply Units - Matrox NRG User Manual

Replacing power supply units

Matrox NRG has fully redundant power supplies. In the event one of the power supply modules fails,
the output load will be completely supported by the second power module. The failed power supply
module can then be replaced without interrupting the power output to connected devices. Although
the power supply modules can be replaced at any time, NRG includes a stiffener bar that must be
physically removed before you can remove either module.
Disconnect the AC power cord from the power supply module you want to replace.
