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.

Table 1-3 Protection Functions of PSM150-AC
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.
2.2Tools for Installation
• Straight screwdriver
• Philips screwdriver
• ESD-preventive wrist strap
2.3Installing & 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.
