Overview

The PSR150-A1 is an AC-input and DC-output power module. The

PSR150-D1 is a DC-input and DC-output power module. Both power

modules provide an output voltage of 12 V and a maximum output of 150

These power modules have the following features:

•Provide output overvoltage, short-circuit, overcurrent, and

overtemperature protections. See Table 1 for the protection and

auto-recovery features of the power modules.

•Two power modules can be connected in parallel to achieve 1+1

redundancy and load sharing.

•Hot swappable. When you hot swap a power module, make sure the

device can operate correctly with the remaining power modules.

IMPORTANT:

After a power module is latched, it cannot restore power supply

automatically after the problems are resolved. Follow this procedure to

restore the power module operation:

1. Disconnect the power cord from the external power supply system.

2. Disconnect the power cord from the power module.

3. Wait a few seconds and then connect the power cord to the powe

module.

4. Connect the power cord to the external power supply system.

Installing and removing the power

module

To prevent device damage and personal injury, strictly follow the

installation and removal procedures illustrated in Figure 3 and Figure 4,

respectively.

Safety guidelines

To prevent device damage and bodily injury, follow these restrictions and

guidelines when you install or remove the power module:

•Wear an ESD wrist strap and make sure the wrist strap makes good

skin contact.

•Before installing the power module, make sure the operating voltage

of the external power supply system is as required by the power

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

the powered device.

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

•Never place the power module in a wet area and prevent fluid from

flowing into the power module.

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

When the internal circuits or components of the power module fail,

contact H3C Support.

Tools

Prepare the following tools for installation and removal:

•Flat-blade screwdriver

•Phillips screwdriver

•ESD wrist strap

Installing and removing the power module

CAUTION:

Before installing or removing the power module, make sure no power

cord is connected to the power module.

The installation and removal procedures are similar for the PSR150-A1

and PSR150-D1 power modules. The following procedures use the

PSR150-A1 power module as an example.

Installing the power module

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

skin contact and is reliably grounded.

2. Unpack the power module and verify that the input mode of the power

module is as required.

3. Remove the filler panel, if any, from the target power module slot.

4. Correctly orient the power module. Grasping the module handle with

one hand and supporting the module bottom with the other, insert the

module slowly into the slot along the guide rails. See callout 1

in Figure 5.

To prevent damage to the power module or the connector on the

backplane of the powered device, insert the power module gently.

If you insert the power module upside down, you will encounter a hard

resistance because of the special structure designs of the slot and

power module. You need to pull out the power module, orient it

correctly, and insert it again.

5. Use a Phillips screwdriver to fasten the captive screws on the power

module to secure it in the chassis. See callout 2 in Figure 5.

If the captive screw cannot be tightly fastened, examine the

installation of the power module.

Figure 5 Installing the power module

Removing the power module

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

skin contact and is reliably grounded.

2. Disconnect the power cord from the power module and the external

power supply.

3. Face the power module to be removed from the powered device.

4. Use a Phillips screwdriver to loosen the captive screws on the power

module until the captive screws are disengaged from the powered

device.

5. Grasping the handle of the power module with one hand, pull it part

way out. Then supporting the power module bottom with the other

hand, pull the power module slowly out of the slot along the guide

rails.

6. Put the removed power module into an antistatic bag.

Connecting the power cord

Use an AC power cord to connect an AC power module to the external AC

power supply system. Use a DC power cord to connect a DC power

module to the external DC power supply system.

Connecting an AC power cord

1. As shown by Figure 6,pull the bail latch leftward.

2. As shown by callout 1 in Figure 7,connect one end of the AC power

cord to the AC-input power receptacle.

3. As shown by callout 2 in Figure 7,pull the bail latch rightward to

secure the power cord plug in place.

4. Connect the other end of the AC power cord to the external AC power

supply system.

Figure 6 Connecting an AC power cord (1)

Figure 7 Connecting an AC power cord (2)

Connecting a DC power cord

1. Correctly orient the DC power cord plug, and insert it into the DC-input

power receptacle on the power module.

If you insert the plug upside down, you will feel hard resistance

because of the special structure designs of the DC-input power

receptacle and the plug. You need to remove the plug, orient it

correctly, and insert it again.

2. Use a flat-blade screwdriver to fasten thetwo screws on the DC power

cord plug to secure the plug to the DC-input power receptacle, as

shown by callout 2 in Figure 8.

3. Connect the other end of the DC power cord to the external DC power

supply system.
