undervoltage input, overvoltage output,
overcurrent output, output short circuit, and
overtemperature.
Redundancy The power modules can operate in redundant
mode, and support load sharing.
Hot swapping You can replace a power module when the
switch is operating.

Installing and removing a power
module
Safety precautions
To avoid possible bodily injury and power module and device
damage, follow these safety precautions:
•When you install and remove a power module, always wear an
ESD wrist strap and make sure it makes good skin contact and
is well grounded.
•Before you install the power module, make sure the voltage of
the power source is the same as the rated voltage of the power
module, and the output voltage of the power module is the same
as the required voltage.
•Do not touch any naked cable or terminal 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 the maintainer for examining and repairing.
Tools
Prepare an ESD wrist strap and a flat-blade screwdriver yourself.

IMPORTANT:
Before installation, make sure the power module model is as
required. For more information about the device requirements,
see the installation guide of the device.
Installing the power module
To avoid bodily injury or device damage, follow the steps in Figure 2
to install the power module.
Figure 2 Installation procedure
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 verify that the power module
model is as required.

3. As shown in Figure 3, with the upside of the power module up,
hold the handle of the power module with one hand and the
bottom of the power module with the other, and then slide the
power module slowly 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.

IMPORTANT:
•To avoid damaging or bending the terminals of the power
module, if the insertion direction is incorrect during the
installation, you must pull the power module out, adjust the
direction, and insert it again.
•To remove the filler panel (if any) from the power module slot
on the device, insert a flat-blade screwdriver through the
handle and pull the filler panel outward along the guide rails,
as shown in Figure 5.
•Keep the filler panel and the packaging box and packaging
bag of the power module for future use.

Connecting the AC power cord
CAUTION:
•The PSR1800-56A power module must use the
high-temperature resistant C15 connector power cord
delivered with the power module.
•Turn off the circuit breaker before connecting the power
cord.

10
To connect the power cord:
1. As shown in Figure 6, plug the female connector end of the AC
power cord into the AC input socket on the switch.
Figure 6 Connecting the AC power cord
2. As shown in Figure 7, use a cable tie to secure the power cord to
the handle of the power module.
Figure 7 Securing the AC power cord

11
3. Plug the other end of the AC power cord into the socket strip of
the power source, and turn on the circuit breaker of the power
source.
4. Examine the LED on the power module. If the input status LED
(AC OK) is steady green, the power cord is successfully
connected. If the LED is off, examine the installation conditions,
troubleshoot the problems, and try again until the LED is normal.
Removing the power module
To avoid bodily injury or device damage, follow the steps in Figure 8
to remove the power module.
Figure 8 Removing procedure
To remove the power module:
1. Turn off the circuit breaker of the power cord.
2. Wear an ESD wrist strap and make sure the strap makes good
skin contact and is reliably grounded.
3. Loosen the cable tie, and remove the power cord.

12
4. As shown in Figure 9, press the latch towards the handle, and
pull the power module along the guide rails until it is part-way
out.
5. Grasp the handle of the power module with one hand, and hold
the bottom of the power module with the other hand to pull the
power module slowly along the guide rails out of the slot.
Figure 9 Removing the power module
6. Put the removed power module on an antistatic mat or into its
package.
NOTE:
If you do not insert another power module into the slot after
removing the power module, install the filler panel to the power
module slot to prevent dust from entering the chassis.
