HP FlexFabric 11900 2500W AC 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

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

nfiguration."

LEDs

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

LED Sign Color Description

Power input

Off

Green The power input is normal.

The power supply has no power input. The input voltage is too low, and the power supply enters the protected state.

LED Sign Color Description

Green The power output is normal.

Power output

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.

Red

Orange

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.

N+1

and

N+N

, the value of N depends on the number of power supply
