Overview

The PSR3000-54AHD power module supports both AC input and high-voltage DC input (240 VDC and 380 VDC). It is hot swappable and provides a maximum output of 3000 W.

Table 1 PSR3000-54AHD power module features

Feature

Description

Protection

Protection against input under-voltage, input over-voltage, output over-voltage, output short circuit, output over-current, and overheat.

Hot swapping

You can install or remove the power module when the device is operating.

Redundancy

The power module can operate in N+1 or N+N redundancy. For more information, see "Power module configuration."

 

The power module shuts down automatically when its temperature exceeds the acceptable range. When the temperature returns to the acceptable range, the power module automatically restarts.

Power module configuration

Follow these guidelines to configure power modules for the device:

·     Determine the total number of power modules based on the actual power consumption, the power module slot number, and power redundancy design.

·     Determine the power module redundancy design based on the power source conditions.

¡ When two mains power inputs are provided, you can configure the power modules in N+N redundancy. N+N must be not greater than the total number of power module slots.

¡ When one mains power input is provided, you can configure the power modules in N+1 or N+N redundancy. N+1 or N+N must be not greater than the total number of power module slots.

·     For easy usage and maintenance, configure a circuit breaker for each power input. The rated current of the circuit breaker must be a minimum of 20 A.

Power cords

The PSR3000-54AHD power module must be used in conjunction with power cords listed in Table 4. Determine the power cord based on the power source conditions.

Installing and removing the power module

Installing the power module

To avoid bodily injury and device damage, follow the procedures in Figure 5 to install a power module.

Figure 5 Power module installation procedure

 

Before the installation, prepare an ESD wrist strap and a flat-blade screwdriver yourself.

Installing the power module

1.     Wear an ESD wrist strap, and make sure the strap makes good skin contact and is correctly grounded.

2.     Thread the flat-blade screwdriver through the hole in the handle of the filler panel and pull the filler panel out.

Skip this step if the target slot does not have a filler panel installed.

Figure 6 Removing a filler panel

 

3.     Unpack the power module.

4.     Correctly orient the power module.

If you install the power module in a left power module slot, make sure the latch is above the handle. If you install the power module in a right power module slot, make sure the latch is below the handle.

5.     Holding the handle of the power module with one hand and supporting the bottom of the power module with the other, slide the power module along the guide rails into the slot until you hear a click.

The power module is foolproof. If the power module is oriented incorrectly, you cannot install the power module into the slot. If you encounter a hard resistance while inserting the power module, pull out the power module, reorient it, and then insert it again.

Connecting the power cord

WARNING

WARNING!

·     Make sure each power cord has a separate circuit breaker unless a PDU power strip is used.

·     Turn off the circuit breaker before you connect the power cord.

 

To connect the power cord:

1.     Plug the power cord connector into the power receptacle of the power module.

Make sure the clasp on the connector secures the connector into the power receptacle.

Figure 9 Connecting the power cord to the power module

 

2.     Connect the other end of the power cord to the power source, and turn on the circuit breaker.

3.     Verify that the power input LED is ON. If the LED is on, the power cord is correctly connected. If the LED is OFF, troubleshoot the installation process.

Removing the power module

To avoid device damage and bodily injury, follow the procedures in Figure 10 to remove the power module.

Figure 10 Power module removal procedure

 

Before you remove a power module, prepare an ESD wrist strap yourself.

Removing the power cord

1.     Turn off the circuit breaker of the power cord.

2.     Wear an ESD wrist strap, and make sure the strap makes good skin contact and is correctly grounded.

3.     Squeezing the connector between your thumb and forefinger, gently pull the power cord out, with your forefinger pressing the clasp upward.

Removing the power module

CAUTION

CAUTION:

Before you insert a removed power module into a power module slot, make sure the LEDs on the power module are off.

 

To remove the power module:

1.     Pressing the latch towards the handle direction, pull the power module out along the guide rails until it is part way out of the slot.

2.     As shown in Figure 12, grasping the handle of the power module with one hand and supporting the bottom of the power module with the other hand, pull the module slowly along the guide rails out of the slot.

Figure 12 Removing the power module

 

3.     Place the power module on an antistatic mat.

4.     Install the filler panel in the power module slot.
