Power supply overview
The AC2500 (JG616A) is a power supply with AC input and DC output. It can provide up
to 2500 W DC output.
The AC2500 has the following features:
Feature Description
Protection function
Support for hot
swapping
Support for
redundancy
CAUTION:
• AC2500 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.
Protection for under-voltage input, over-voltage input,
over-voltage output, output short circuit, under-current
output, over-current output, and overheat.
You can plug in or unplug the power supply when the
device is operating properly.
The power supplies can operate in N+1 or N+N redundant
mode. For more information, see "Power supply
co
nfiguration."

CAUTION:
• If a power supply has no power input, or the connected circuit breaker is off, but
another power supply is providing power 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.

The power supply encounters exceptional
power output problems. In other words, when
output short circuit, over-current output,
over-voltage output, under-voltage input, or
remote shutdown occurs, the power supply
enters the protected state.
The temperature of the power supply is too
high, and the power supply enters the
protected state.

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, be sure to configure a proper circuit breaker for
each power input. The rated current of the circuit breaker must be more than 20 A.
NOTE:
In the term
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 to provide power supply, so the chassis
has a power supply slot without a blank panel. For this slot, you can 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 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 the Figure 3).

4. 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 secure the
power supply.
Connecting the power cord
ARNING!
• Make sure each power cord has a separate circuit breaker.
• Turn off the circuit breaker before connecting the power cord.
To connect the power cord:
1. Plug the AC power cord connector into the receptacle of the power supply.
2. Route the power cord along the cabling rack, and fasten the power cord by using
cable ties.

NOTE:
The cabling rack position varies by switch model. Route the cable as required. For
how to fasten the power cord connected to a vertically-installed power supply,
see Figure 5
Figure 5 Fastening the power cord connected to a vertically-installed power supply
3. Plug the other end of the power cord into an AC power receptacle of the power
source, and turn on the connected circuit breaker.
4. Verify that the input status LED is ON. It indicates that the power cord is correctly
connected. If the input status LED is OFF, troubleshoot the installation process until
the input status LED is ON.

Removing the power cord
1. Turn off the circuit breaker of the power cord.
2. Wear an ESD-preventive wrist strap, and make sure the wrist strap makes good skin
contact and is properly grounded.
3. Remove the cable ties, and pull the power cord out.
CAUTION:
fter 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.
