Power Supply User Guide

Part number: 5998-4091

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

Protection for under-voltage input, over-voltage input,

over-voltage output, output short circuit, under-current

output, over-current output, and overheat.

Support for hot

swapping

You can plug in or unplug the power supply when the

device is operating properly.

Support for

redundancy

The power supplies can operate in N+1 or N+N redundant

mode. For more information, see "Power supply

configuration."

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.

LEDs

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

description.

LED Sign Color Description

Power

input AC Off

The power supply has no power input.

The input voltage is too low, and the power

supply enters the protected state.

Green The power input is normal.

LED Sign Color Description

Power

output DC

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, 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 enters 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 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, 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

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 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).

(2) Remove the blank panel

3. Unpack the power supply.

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.

NOTE:

The blank panel is printed with a dia

ram of correct installation direction. You can

follow the instruction to install the power supply. As shown in Figure 4 (vertical

installation), be sure of the correct direction of the power supply.

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 a power supply

Figure 6 illustrates the flow for removing a power supply. Strictly follow the sequence to

avoid possible dangers.

Figure 6 Removal 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 "Install the

blank panel" in the figure above.

Before removing a power supply, prepare an ESD-preventive wrist strap and a Phillips

screwdriver.

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.

Removing 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 7,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 module slowly along the guide rails out of the slot.

Figure 7 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.

CAUTION:

Before inserting a removed power supply into a power supply slot, make sure the

LEDs on the power supply are both off.
