HPE LSUM1DC2400 Power Supply User Guide
Part number: 5998-3021s
▌Power supply overview
The LSUM1DC2400 (JC747A) is a power supply with DC input and DC output. It can
provide up to 2400 W of DC output.
The LSUM1DC2400 has the following features:
Table 1 Features of the LSUM1DC2400 power supply
Feature
Description
Protection function
Protection for under-voltage input, over-voltage input,
over-voltage output, output short circuit, over-current
output, and overheat.
Support for hot
swapping
You can plug in or unplug the redundant power supply when
the device is operating properly.
Support for
redundancy
The power supplies can work in N+1 or N+N redundant
mode. For more information, see “Power supply
configuration.”
CAUTION:
• LSUM1DC2400 cannot work with other models of power supplies in the
same device.
• When the temperature of the power supply is higher than the upper limit of
the operating temperature, the power supply automatically shuts down.
When the temperature falls into the normal range, the power supply
automatically starts.

LEDs
A power supply has two status LEDs. The following table lists the LED status and
description.

Description
Off
The input voltage is too low, and the power supply
enters the protected state.

Description
Green
The power output is normal.
Red
The power supply encounters exceptional power
output problems. In other words, when output short
circuit, over-current output, over-voltage output,
under-voltage input, over-temperature, or remote
shutdown occurs, the power supply enters the
protected state.
Orange
The temperature of the power supply is too high,
and the power supply will enter the protected state.
CAUTION:
• If a power supply has no power input, or the connected circuit breaker is off,
but another power supply is providing power supply to the system, it is
normal that the power output status LED is red.
• After the circuit breaker that connects to a power supply is off, it is normal that
the LEDs on the power supply last on for a while.

Power supply configuration
You can determine the number of power supplies to be configured for the system
according to the actual power consumption and power supply conditions.
•
In an environment with two mains power inputs, you can configure N+N
redundant mode.
•
In an environment with only one mains power input, you can configure N+1 or
N+N redundant mode.
•
For easy usage and maintenance, configure a proper circuit breaker for each
power input. The rated current of the circuit breaker must be more than 80 A.
NOTE:
In the terms N+1 and N+N, the value of N depends on the number of power
supply slots in the device. N+1 or N+N must not be more than the total number
of power supply slots.
▌Installing and removing a power supply
Installing a power supply
Figure 2 illustrates the flow for installing a power supply. Strictly follow the sequence
to avoid possible dangers.

Figure 2 Installation flow of a power supply
NOTE:
The device needs at least one power supply, so the chassis has a power supply
slot without a blank panel. For this slot, skip “Remove the blank panel” in the
figure above.
Before the installation, prepare an ESD-preventive wrist strap and a Phillips
screwdriver.
Installing the power supply
1. Wear an ESD-preventive wrist strap, and make sure that the wrist strap makes
good skin contact and is properly grounded.
2. Use the Phillips screwdriver to unfasten the captive screws on the blank panel,
and remove the blank panel from the slot to be used (see callout 2 in Figure 3).

(2) Remove the blank panel
NOTE:
A power supply can be vertically or horizontally installed according to the power
supply slot, but the installation methods are similar. This document takes the
vertical installation method as an example, and gives different diagrams for key
steps.
3. Take the power supply out of the package.
4. The blank panel is printed with a diagram of correct installation direction. You can
follow the instruction to install the power supply. As shown in Figure 4 (vertical
installation) and Figure 5 (horizontal installation), be sure of the correct direction
of the power supply. Holding the handle of the power supply with one hand and
supporting the bottom of the power supply with the other, slide the power supply
along the guide rails into the slot.

5. Press the handle back into the notch of the power supply.
6. Use the Phillips screwdriver to fasten the captive screw on the handle to fix the
power supply.
Connecting the power cord
WARNING!
• Make sure each wire has a separate circuit breaker.
• Turn off the circuit breaker before you connect each wire.
To connect the power cord:
1. Plug the connector of the DC power cord supplied with the power supply into the
receptacle on the power supply.
2. Fasten the screw of the power cord to prevent a falloff.

Figure 6 Connecting the power cord
(1) Plug the DC power cord connector into the receptacle on the power supply.
(2) Fasten the screw of the power cord.
3. 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 (+).
CAUTION:
When you connect the DC power cord to the power source, make sure the
circuit breakers are turned off for both the positive and negative wires.
Removing a power supply
Figure 7 illustrates the flow for removing a power supply. Strictly follow the sequence
to avoid possible dangers.

NOTE:
The device needs at least one power supply, so the chassis has a power supply
slot without a blank panel. For this slot, skip “Install the blank panel” in the figure
above.
Before you remove a power supply, prepare an ESD-preventive wrist strap and a
Phillips screwdriver.
Removing the power cord
CAUTION:
After the circuit breaker that connects to a power supply is off, it is normal that
the LEDs on the power supply last on for a while.
To remove the power cord:
1. Turn off the circuit breakers of the wires.
2. Wear an ESD-preventive wrist strap, and make sure the wrist strap makes good
skin contact and is properly grounded.
3. Loosen the screw that fastens the power cord, and pull the power cord out.
10
Removing the power supply
CAUTION:
Before you insert a removed power supply into a power supply slot, make sure
the LEDs on the power supply are both off.
To remove the power supply:
1. Use the Phillips screwdriver to unfasten the captive screw on the power supply.
2. Hold the captive screw and pull out the handle of the power supply.
3. As shown in Figure 8, grasp the handle of the power supply with one hand and
pull it out a little, support the bottom of the power supply with the other hand, and
then pull the power supply slowly along the guide rails out of the slot.
Figure 8 Removing the power supply
4. Put the power supply on an antistatic mat.
5. Install the blank panel back to the power supply slot, and fasten the captive
screws.
