Installing and removing the power supply

Safety precautions

• Wear an ESD wrist strap and make sure the wrist strap makes good skin contact.
• Before installing the power supply, make sure the operating voltage of the external power supply system is as required by the power supply, and the output voltage of the power supply is as required by the powered device.
• To avoid bodily injury, do not touch any bare wire or terminal.
• To avoid power supply damage, do not open the power supply. When the internal circuits or components of the power supply fail, contact Intelbras Support.
• Before installing or removing the power supply, make sure no power cord is connected to the 
power supply.

Tools
An ESD wrist strap is required for installing and removing the power supply and connecting the power cord. Prepare an ESD wrist strap yourself.

Installing the power supply

• To prevent damage to the power supply or the connector on the backplane of the powered device, insert the power supply gently.
• If you insert the power supply upside down, you will encounter a hard resistance because of the special structure designs of the slot and power supply. You need to pull out the power supply, orient it correctly, and insert it again.
• Before installing the power supply on a switch, make sure it matches the switch model. For more information, see the installation guide for the switch.
• Keep the filler panel, packaging box, and packaging bags for the power supply secure for future use.

1. Unpack the power supply and verify that the input mode of the power supply is as required.
2. Correctly orient the power supply (with the lettering on it upward), grasp the handle of the power supply with one hand and support its bottom with the other, and slide the power supply slowly along the guide rails into the slot. Make sure the latch on the power supply clicks into place.

If the power supply slot has a filler panel, put your finger into the hole in the filler panel and then pull the filler panel out of the slot gently.

Connecting the power cord

• Use the power cord provided with the power supply for connection. The power cord provided with the power supply uses a C15 connector that is designed to withstand high temperatures.
• Provide a separate circuit breaker for each power cord.
• Before connecting a power cord, make sure the circuit breaker for the power feed is turned off.
  1. Connect the female connector of the power cord to the power input receptacle on the power supply.
  2. Use a cable tie to secure the power cord to the handle of the power supply.

Removing the power supply

• To avoid bodily injury or switch damage, strictly follow the procedure described in this section to remove the power supply.
• If you are not to install a new power supply after removing the old one, install a filler panel in the slot in time.
  1. Turn off the circuit breaker for the power feed to the power supply.
  2. Remove the cable tie from the power cord, and then remove the power cord.
  3. Pressing the latch towards the handle direction, pull the power supply part way out of the slot.
  4. Grasping the handle of the power supply with one hand and supporting its bottom with the other, pull the power supply slowly out of the slot along the guide rails.
