6-5 Power Supply

5015M-UR/5015M-NTR

The Series3800/S110R-1 (5015M-UR/5015M-U/5015M-NTR/5015M-NT) has a 450

watt redundant power supply conﬁ guration consisting of two hot-swap power mod-

ules. The power supply modules have an auto-switching capability, which enables

them to automatically sense and operate with a 100V - 240V input voltage.

Power Supply Failure

If either of the two power supply modules fail, the other module will take the full

load and allow the system to continue operation without interruption. The Univer-

sal Information LED on the control panel will blink red slowly and remain so until

the failed module has been replaced. Replacement modules can be ordered. The

power supply modules have a hot-swap capability, meaning you can replace the

failed module without powering down the system.

Removing/Replacing the Power Supply

You do not need to shut down the system to replace a power supply module. The

redundant feature will keep the system up and running while you replace the failed

hot-swap module. Replace with the same model.

1. Removing the power supply

First unplug the power cord from the failed power supply module. To remove the

failed power module, push the release tab (on the back of the power supply) to

the side and then pull the module straight out (see Figure 6-6). The power supply

wiring was designed to detach automatically when the module is pulled from the

chassis.

2. Installing a new power supply

Replace the failed power module with another PWS-451-1R power supply module.

Simply push the new power supply module into the power bay until you hear a click.

Finish by plugging the AC power cord back into the module.
