Connecting the AC Power Cable

Connecting the AC Power Cable


To avoid electric shock, do not connect power cables while the power is on.

  • Do not power on a router before you finish connecting power cables and network cables.
  • Each router has its own power cables delivered as accessories. The power cables can only be used on the router in the same package and cannot be used on any other device.

The AC power cable parameters vary in different countries or regions. The figures in this section are for reference only and may differ from the cables delivered.

Tools and Accessories

  • ESD wrist strap
  • AC Power Cable
  • AC terminal locking latch


  1. Verify that the router is reliably grounded.
  2. Set the power switch to OFF.
  3. Wear an ESD wrist strap. Ensure that the ESD wrist strap is grounded and in a close contact with your wrist.
  4. Connect the AC power cable.
    1. Connect one end of the AC power cable to the power socket on the router.
    2. Connect the other end of the AC power cable to an AC power outlet.

  5. Connect the AC terminal locking latch.
    1. Insert the AC terminal locking latch into the jack on the rear panel of the router.
    2. Adjust the AC terminal locking latch to a proper position.
    3. Lock the AC power cable with the AC terminal locking latch.

Follow-up Procedure

Perform the following operations after connecting the AC power cable:

  • Verify that the AC power cable is securely connected to the power socket on the router.
  • If multiple routers are installed, attach labels to both ends of each power cable and write numbers on the labels to identify them.
