Overview
The PSR2400-54D DC-input and DC-output power module is hot
swappable and provides a maximum output of 2400 W.
Table 1 PSR2400-54D power module features
Feature Description
Protection
Protection against input under-voltage, input
over-voltage, output over-voltage, output short
circuit, output under-current, output
over-current, and overheat.
Redundancy The power modules can operate in N+1 or N+N redundancy. For more information, see "Power
module configuration."
Hot swapping You can install or remove a power module
when the device is operating.
The power module shuts down automatically when its temperature
exceeds the acceptable range. When the temperature returns to the
acceptable range, the power module automatically restarts.

Power module configuration
Follow these guidelines to configure power modules for the device:
•Determine the total number of power modules based on the
actual power consumption, the power module slot number, and
power redundancy design.
•Determine the power module redundancy design based on the
power source conditions.
{When two mains power inputs are provided, you can
configure the power modules in N+N redundancy. N+N must
be not greater than the total number of power module slots.

5
{When one mains power input is provided, you can configure
the power modules in N+1 or N+N redundancy. N+1 or N+N
must be not greater than the total number of power module
slots.
•For easy usage and maintenance, configure a circuit breaker for
each power input. The rated current of the circuit breaker must
be a minimum of 120 A.

Installing and removing the power
module
Installing the power module
To avoid bodily injury and device damage, follow the procedures
in Figure 2 to install a power module.
Figure 2 Power module installation procedure
Before the installation, prepare an ESD wrist strap and a flat-blade
screwdriver yourself.

7
Installing 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 blank panel from the target power module slot.
{If the blank panel is as shown in Figure 3, thread the
flat-blade screwdriver through the hole in the handle of the
blank panel and pull the blank panel out.
{If the blank panel is as shown in Figure 4, put your forefinger
in the hole in the blank panel and pull the blank panel out.
Skip this step if the target slot does not have any blank panel
installed.

Figure 4 Removing a blank panel (2)
3. Unpack the power module.
4. Correctly orient the power module.
If you install the power module in a left power module slot, make
sure the latch is above the handle. If you install the power
module in a right power module slot, make sure the latch is
below the handle.
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 you
hear a click.
The power module is foolproof. If the power module is oriented
incorrectly, you cannot install the power module into the slot. If
you encounter a hard resistance while inserting the power
module, pull out the power module, reorient it, and then insert it
again.

Connecting the power cord
WARNING!
•Make sure each power cord has a separate circuit breaker.
•Before you connect the DC power cord to the DC source
terminal block. Make sure the circuit breakers are turned off.
To connect the power cord:
1. Insert the power cord connector into the DC input receptacle on
the power module.
2. Fasten the screw to secure the connector in place.
3. Connect the two wires at the other end of the DC power cord to
the DC source terminal block.

10
Removing the power module
To avoid device damage and bodily injury, follow the procedures
in Figure 6 to remove the power module.
Figure 6 Power module removal procedure
Before you remove the power module, prepare an ESD wrist strap
yourself.
Removing the power cord
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 screw that secures the power cord connector to the
power module, and pull the power cord out.

11
Removing the power module
CAUTION:
•Before you insert a removed power module into a power
module slot, make sure the LEDs on the power module are off.
•Avoid scalding your hands when you remove the power
module.
To remove the power module:
1. Pressing the latch towards the handle direction, pull the power
module out along the guide rails until it ispart way out of the slot.
2. As shown in Figure 7, grasping the handle of the power module
with one hand and supporting the bottom of the power module
with the other hand, pull the module slowly along the guide rails
out of the slot.

3. Place the power module on an antistatic mat.
4. Install the blank panel in the power module slot.
