CAUTION: Remove the power cable from the PSU before removing the PSU. Also, do not connect the power
cable before you insert the PSU in the switch.
NOTE: To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC or DC Power Ports, use an
external surge protection device (SPD) at the AC or DC input of the router.

● Off—PSU is off.
AC or DC power supply installation
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the
switch.
NOTE: Ensure that you correctly install the PSU. When you install the PSU correctly, the power connector is on the left
side of the PSU.
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. If you are only using one power supply, install the
power supply in the first slot, PSU1. Install a blank plate in the second slot, PSU2.
1. Remove the PSU slot cover from the S5148F-ON switch using a small #1 Phillips screwdriver.
2. Remove the PSU from the electro-static bag.
3. Insert the PSU into the switch PSU slot—insert the exposed PSU connector first.
The PSU slot is keyed so that you can only fully insert the PSU in one orientation. When you install the PSU correctly, it
snaps into place and is flushed with the back of the switch.

4. Plug in the appropriate AC 3-prongs cord from the switch PSU to the external power source.

The S5148F-ON switch powers up when you connect the cables between the power supply and the power
source.
