About the power supply
CAUTION:
•
Do not install the PSR2400-D power supply on the same
device with other power supplies.
•
The power supply shuts down automatically when its
temperature exceeds the acceptable range. When the
temperature returns to the acceptable range, the power
supply restarts automatically.
The PSR2400-D is a DC input and DC output power supply. It
provides a maximum output of 2400 W.
The power supply has the following features:
•
It provides protection against input undervoltage, input
overvoltage, output overvoltage, output short circuit, output
overcurrent, and overtemperature conditions.
•
It is hot swappable. You can install or remove it when the device
is operating. Before removing it, make sure the remaining power
supplies can provide sufficient power for the device.
•
You can use PSR2400-D power supplies to configure N+1 or
N+N power supply redundancy for the device. For more
information, see "Power supply configuration guidelines."

the following conditions:
•Output short-circuit
•Output overcurrent
•Output overvoltage
•Input undervoltage
•Overtemperature
•Remote shutdown
Orange High temperature alarm.
NOTE
:
•
The power output LED on a power supply is red when it
has
no power input or its connected circuit breaker is off but
another power supply provides power to the device.
•
After the circuit breaker of the power supply
is switched off,
the LEDs on the power supply will remain on for a while.

Power supply configuration guidelines
Determine the number of power supplies based on the system power
consumption and the power supply configuration based on the power
input mode.
•
In an environment with two mains power inputs, configure N+N
power supply redundancy.
•
In an environment with only one mains power input, configure
N+1 or N+N power supply redundancy.
5
•
Provide a circuit breaker for power input of each power supply.
Make sure each circuit breaker has a current rating not less than
80 A.
NOTE:
The value of N depends on the number of power supply slots in
the device. N+1 or N+N must not be greater than the total number
of power supply slots.
Installing and removing the power
supply
Installing the power supply
To avoid possible damage, strictly follow the procedure in Figure 2 to
install the power supply.
Figure 2 Power supply installation procedure

Before the installation, prepare an ESD wrist strap and a Phillips
screwdriver yourself.
Installing the power supply
CAUTION:
Before inserting a removed power supply into a power supply
slot, make sure both LEDs on the power supply are off.
To install the power supply:
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 power supply slot. Use
the Phillips screwdriver to loosen the captive screws on the filler
panel, and then remove the filler panel out of the target slot.
The device requires a minimum of one power supply to supply
power so it comes with one slot that does not have a filler panel
installed. If you install the power supply in this slot, skip this
step.
3. Unpack the power supply. Make sure the power supply model is
as required.
4. Use the Phillips screwdriver to loosen the captive screw on the
power supply handle and then pull the handle outward.
5. Correctly orient the power supply. Holding the power supply
handle with one hand and supporting its bottom with the other,
push the power supply slowly into the slot along the guide rails.
A power supply slot can be vertical or horizontal. The power
supply installation method is similar for vertical and horizontal
power supply slots. This procedure installs the power supply in a
vertical slot.

Figure 3 Install the power supply into a vertical slot
6. Press the handle back into the notch of the power supply.
7. Use the Phillips screwdriver to fasten the captive screw on the
handle to secure the power supply to the chassis.
Connecting the power cord
WARNING
!
•
Make sure each power cord has a separate circuit breaker.
•
Turn off the circuit breaker before connecting the power
cord.
•
Use the power cord or ring terminals provided by H3C to
meet the current requirements and match
the power supply
terminals.
