Overview
The PSR650C-12Ais anAC-input, DC-output power module, and the
PSR650C-12D is a DC-input and DC-output power module. They
each can provide a maximum output of 650 W.
The power modules support 1+1 redundancy and load sharing and
are removable. They also provide output overcurrent, output
overvoltage, output short circuit, and overtemperature protections.

LEDs
The PSR650C-12A/PSR650C-12D power module provides three
red-green status LEDs.
Table 2 LED description
LED Status Description
INPUT
Green The power is being input correctly.
Red A power input problem has occurred
because the input voltage is out of the
rated voltage range.
Off
No power is being input because one of
the following conditions exists:
•The power module is faulty.
•The power cord is disconnected.
•The power source is unavailable.

and enters protection state because of
input undervoltage, output short circuit,
output overcurrent, output overvoltage,
overtemperature, or fan failure.
•The power module is switched off.
Off
No power is being output because one of
the following conditions exists:
•The power module is faulty.
•The power cord is disconnected.
•The power source is unavailable.
FAN
Green The fans are operating correctly.
Red
The fans are operating incorrectly because
one of the following conditions exists:
•A fan failure has occurred.
•The power module is switched off.
Off
The fans stop operating because one of
the following conditions exists:
•The power module is faulty.
•The power cord is disconnected.
•The power source is unavailable.

Installing and removing the power
module
The installation and removal procedures are the same for the
PSR650C-12A and PSR650C-12D power modules. This section
uses the PSR650C-12A as an example.
Safety precautions
To avoid possible bodily injury and power module and device
damage, follow these safety precautions:
•
When you install and remove the power module, always wear an
ESD wrist strap and make sure it makes good skin contact and
is reliably grounded.
•
Before you install the power module, make sure the output
voltage of the power module is as required by the device.
•
When you move the power module, support its bottom instead of
only holding the power handle.
•
To avoid device damage, do not install power modules of
different models on the same device.
•
Do not touch any bare cables or terminals of the power module.
•
Do not place the power module in a wet area, and prevent liquid
from flowing into the power module.
•
Do not open the power module. When the internal circuits or
components of the power module fail, contact H3C Support.
Installing the power module
WARNING!
Turn off the power switch before installing the power module.

To avoid bodily injury and device damage, follow the procedure in
Figure 3 to install a 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. Remove the filler panel, if any, from the target slot.
Keep the removed filler panel for future use.
3. Unpack the power module. Make sure the power module model
is as required.
4. Correctly orient the power module.
5. Holding the handle of the power module with one hand and
supporting the bottom of the power module with the other, slide
the power module along the guide rails into the slot until the

power module is fully seated in the slot. Then fasten the captive
screws.
If you encounter a hard resistance while inserting the power
module or fastening a captive screw, pull out the power module,
reorient it, and then insert it again.

Figure 5 Power module removal procedure
To remove the power module:
1. Turn off the circuit breaker of the power cord.
2. Prepare an antistatic mat to place the removed power module.
3. Wear an ESD wrist strap, and make sure the strap makes good
skin contact and is reliably grounded.
4. Switch off the power module.
5. Remove the power cord connected to the power module.
6. Use a Phillips screwdriver to loosen the captive screws on the
power module.
7. Holding the power module handle with one hand and supporting
the bottom of the power module with the other, gently pull the
power module out.
8. Put the removed power module on the antistatic mat.

To connect the AC power cord:
1. Unpack the power cord, and verify that the power cord model is
correct.
2. Connect the power cord to the power receptacle of the power
module. Make sure the power cord is securely inserted into the
power receptacle.
3. Use a cable tie to secure the power cord to the handle of the
power module.
4. Connect the other end of the power cord to the AC power
source.

Connecting the DC power cord
WARNING!
•
Make sure each power module has a separate circuit
breaker.
•
Turn off the circuit breaker before connecting the power
cord.
To connect the DC power cord:
1. Remove the protection cover from the power module.
2. Remove the screw on the wiring terminal with a Phillips
screwdriver.
3. Connect one ends of the wires to the power input terminals on
the power module, with the negative wire (– or L–) to the
negative terminal (–) and the positive wire (+ or M/N) to the
positive terminal (+).
4. Put the protection cover on the wiring terminals.
5. Connect the other ends of the wires to the DC power source
wiring terminals, with the negative wire (– or L–) to the negative
terminal (–) and the positive wire (+ or M/N) to the positive
terminal (+).
