Note: Spare PSUs can be ordered
Spare PSUs can be ordered from your local sales representative so they can be ready
when needed.
The PSU
The SG4500 Series PSU is a self-contained power supply unit that slides into either of two slots
located at the rear of the appliance.
Figure 4.1. A PSU Module
The PSU features a black handle which should be used for lifting as well as for applying pressure
when inserting or pulling out the module. To the top-left of the handle is a locking switch which
should be pressed to one side to disengage the lock when removing the PSU from a slot.
The PSU does not have an Off/On switch and comes into operation as soon as a power cord is
inserted and external power is applied.
Important: Dusty environments reduce PSU fan lifetimes
SG4500 Series PSU fans are designed to work in environments with reasonable air
quality. Elevated dust levels in the surrounding air can substantially reduce the
operating lifetimes of PSU fan modules.
Using CorePlus Hardware Monitoring to Detect Failure
The Hardware Monitoring (HWM) functions of CorePlus should be used to remotely monitor the
hardware state of the SG4500 Series and associated PSUs. If only one PSU is operating then this is
shown through such monitoring regardless if this is intentional and a PSU filler module occupies
an empty PSU slot.
PSU failure in a single PSU system will result in a total loss of hardware functionality. For this
reason, dual redundant PSUs are the recommended configuration.
