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.

4
•Before you install the power module, 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.
•Do not touch any 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.
•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 an ESD wrist strap and a flat-blade screwdriver yourself.
Installing and removing the power module
Make sure the power module model is compatible with the device.
For more information about hardware compatibility, see the installation
guide for the device.
Installing the power module
To avoid bodily injury or device damage, follow the procedure
in Figure 2 to install the power module.
Figure 2 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.

5
2. Unpack the power module and verify that the power module
model is as required.
3. Remove the filler panel as shown in Figure 3, if any, from the
target power module slot.
{Put your finger into the hole in the filler panel and pull the
filler panel out along the guide rails.
{Insert a flat-blade screwdriver through the handle on the filler
panel and pull the filler panel out along the guide rails.
Figure 3 Removing a filler panel
4. Insert the power module into the slot, as shown in Figure 4:
a. Correctly orient the power module with the characters
upward.
b. Holding the power module handle with one hand and
supporting the power module bottom with the other, slide the
power module along the guide rails into the slot. When the
power module is completely inserted into the slot, you can
hear that the latch of the power module clicks into the slot.
If the power module is not aligned with the slot, pull out the
power module, adjust its direction, and insert it again.

IMPORTANT:
Keep the filler panel and the packaging box and packaging bag
of the power module for future use.
Connecting the DC power cord
WARNING!
•Make sure the power cord has a separate circuit breaker.
•Turn off the circuit breaker before connecting the power
cord.
IMPORTANT:
Use the DC power cord provided with the power module.
To connect the power cord:
1. As shown in Figure 5, plug the female connector end of the DC
power cord into the DC-input receptacle on the power module.
2. Use a flat-blade screwdriver to fasten the screws on the female
connector to secure the power cord to the receptacle.

7
3. Connect the other end of the DC power cord to the DC power
source, and turn on the circuit breaker.
4. Examine the IN OK LED on the power module. If the LED is
steady green, the power cord is connected correctly. If the LED
is off, examine the installation, troubleshoot the problems, and
try again until the LED is steady green.

Removing the power module
To avoid bodily injury or device damage, follow the procedure
in Figure 6 to remove the power module.
Figure 6 Removing procedure

8
To remove the power module:
1. Turn off the circuit breaker at the power input end.
2. Wear an ESD wrist strap and make sure the strap makes good
skin contact and is reliably grounded.
3. Remove the power cord.
4. As shown in Figure 7, press the latch towards the handle, and
pull the power module part way out of the slot along the guide
rails.
5. Holding the power module handle with one hand and supporting
the power module bottom with the other, pull the power module
slowly out of the slot along the guide rails.
6. Put the removed power module on an antistatic mat or into its
package.
7. If you are not to insert a power module into the empty slot, insert
the filler panel into the slot to prevent dust from entering the
chassis.
