AC Power Supply Module

Chapter 1 Introduction

1.1 Overview of the Product

The PSM150-AC is an AC-input and DC-output power supply
module. It can convert the input voltage to 12 Volts with the
maximum output power of 75 Watts. The power supply
module is fully hot swappable, helping to ensure no system
interruption during installation or replacement. PSM150-AC is
applicable to multiple TP-Link switch models.

Note:

• Hot-swap control function will be checked when

PSM150-AC is powered on but has not been inserted into
the switch. If the Fault LED is on under this condition,
please do not insert PSM150-AC into the switch,
otherwise the power supply module or the powered
devices may be damaged.

• The failure of output over-voltage or over-current may

cause the power LED to flash.

and output over-current protection .

Redundant backup

Supports dual power modules combining in p arallel to

implement 1+1 redundancy for uninterruptible power

supply.

Hot Swappable

In the case of 1+1 redundant power supply system, the

PSM150-AC can be plugged out or plugged in without

shutting down the switch.

Note: When the power supply module is locked or auto-retry
continually, you can try the following steps to restore the
device.

1. Disconnect the power cord from the external power
supply system.

2. Disconnect the power cord from the power supply
module.

3. Remove the power supply module from the switch.

4. Insert the power supply module again.

5. Connect the power cord to the power supply module
again.

6. Connect the other end of the power cord to the external
supply system.

Chapter 2 Installation

The process of installation and removal of the power supply
module is illustrated in Figure 2-1 and Figure 2-2.

Figure 2-1 The Installation Process

Figure 2-2 The Removal Process

Note: For safety considerations, the above process are

recommended by TP-Link, however, PSM150-AC can also
support installation or removal when the AC power supply is
on.

2.1 Safety Information

To avoid damage to the power supply module and the
equipment and bodily injury, please observe the following
notes:

• When you install and remove the power supply module,

please wear an ESD-preventive wrist strap, and make sure
that it has good skin contact and is well grounded.

• Before installing the power supply module, make sure that

the voltage of external power supply system is the same
with the voltage marked in the power supply module, and
the output voltage of the power supply module is the
same with the required voltage of the powered devices in
order to prevent damaging the power supply module or
the powered devices.

• Do not touch any exposed wires or terminals to avoid

bodily injury.

• Do not place the power module in a humid place or let the

liquid into the power supply module.

• If there is a failure inside the module, please contact

service personnel, instead of opening the housing of the
module.

2.2 Tools for Installation

• Straight screwdriver

• Philips screwdriver

• ESD-preventive wrist strap

2.3 Installing & Removing the Power Supply Module

• Installing the Power Supply Module

1. Wear an ESD-preventive wrist strap, and make sure that it
has good skin contact and is well grounded.

2. Grip the handle of the module with one hand, and hold the
bottom of the module using your other hand. Gently push
the module in along the slot guide rail until the module is
flush with the switch, as shown in Figure 2-3.

Figure 2-3 Install Power Supply Module

3. Tighten the captive screws with a Phillips screwdriver to
fix the power supply module in place.

• Removing the Power Supply Module

1. Wear an ESD-preventive wrist strap, and make sure that it
has good skin contact and is well grounded.

2. Remove the power cord from the external power supply
system and the power module.

3. Use a Phillips screwdriver to loosen the captive screws at
both sides of the power supply module until all spring
pressure is released.

4. Pull the handle with one hand towards you along the guide
rails, and hold the bottom of the module using your other
hand, until it completely comes out of the switch chassis.

Note:

When installing or removing a power supply module, pay
attention to the following points:

• Make sure that the power supply module is set correctly

in the operation of installation.

• Do not use too much force in the installation. If resistance

is encountered or positions of the power supply module
appear larger during installation, you must first remove
the module and then reinstall the module.

• If screws cannot be tighten, it may be due to the power

supply module is not installed properly. Please check
carefully.

• In order to better protect the power supply module during

removal, it is recommended that you package it in an
antistatic bag.

2.4 Connecting the Power Cord

• Connecting the Power Cord

After the power supply module is installed on the switch,
please plug the female connector of the provided power cord
into the power socket of the device, and the male connector
into a power outlet as the following figure shows.

Figure 2-4 Connect the Power Cord

2.5 Verifying the Installation

To verify the installation status of PSM150-AC, firstly, please
make sure the two captive screws on PSM150-AC are
tightened, then connect the power cord and check the LEDs
of PSM150-AC. If the Power LED is on while Fault LED is off, it

indicates that the AC power input is good and the device is
working properly, and the installation of PSM150-AC has been
successful.
