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
W.
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
r
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.
Figure 3 Installation procedure
Figure 4 Removal procedure
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 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.
