Overview

Introduction

The PSR300-12A2 is an AC-input and DC-output power module. The

PSR300-12D2 is a DC-input and DC-output power module. They

provide a maximum output power of 300 W.

The PSR300-12A2 and PSR300-12D2 power modules have the

following features:

•Self-protected against input overcurrent, input undervoltage,

output overvoltage, output short-circuit, and overtemperature.

•Support for 1+1 redundancy and load sharing.

•Hot swappable.

LEDs

The power module uses power input and power output LEDs to

indicate the power input and output status, respectively.

Table 2 LED description

LED Status Description

Power input status

LED (AC OK or

Input)

Off No power is being input or an

input failure has occurred.

On Normal power input.

Power output status

LED (DC OK or

Output)

Off No power is being output or an

output failure has occurred.

On Normal power output.

If the power input LED is on but the output LED is off, an output issue

might have occurred. To resolve the issue:

1. Turn off the power switch on the power module and reconnect

the power cord.

This operation resolves the power module failure caused by an

output overvoltage, output short-circuit, or output overcurrent

condition. The power module shuts down and latches off if one

of these conditions occurs and cannot automatically restore

operation.

2. If the issue persists, the temperature might be high. Take

measures to decrease the temperature to an acceptable range.

The power module will automatically restore operation.

Safety precautions

To avoid possible bodily injury and power module and device

damage, follow these safety precautions:

•When installing and removing the power module, always wear

an ESD wrist strap and make sure it makes good skin contact.

•Make sure the voltage of the power source is as required by the

power module, and the output voltage of the power module is as

required by the device.

•To avoid bodily injury, do not touch any bare wire or terminal.

•Do not place the power module in a wet location, and prevent

liquid from flowing into the power module.

•To avoid power module damage, do not open the power module.

If the internal wires or units are faulty, contact H3C Support.

Tools

When installing and removing a power module and power cord, you

must wear an ESD wrist strap. Prepare it yourself.

Installing and removing the power module

The installation and removal procedures are similar for the

PSR300-12A2 and PSR300-12D2 power modules. The following

procedures use the PSR300-12D2 power module as an example.

Installing the power module

CAUTION:

To avoid bodily injury and device damage, strictly follow the

procedure in Figure 3 to install the power module.

Figure 3 Power module installation procedure

To install the power module:

1. Wear an ESD wrist strap and make sure the strap makes good

skin contact and is reliably grounded.

2. Unpack the power module and make sure the power module

model is as required.

Keep the power module package secure for future use.

3. As shown in Figure 4, correctly orient the power module (with

the lettering on it upwards). Grasping the module handle with

one hand and supporting the module bottom with the other,

push the module slowly into the slot along the guide rails. Make

sure the power module has good contact with the backplane

connectors.

The power module and power module slot are designed to

prevent disorientation and misalignment. If you cannot insert the

power module smoothly into the slot, the orientation might be

wrong or the power module is not aligned correctly with the slot.

Pull out the power module, reorient the power module or realign

it with the slot, and insert it again.

4. When the power module is fully seated in the slot, fasten the

captive screw on the power module.
