WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the safety cover
removed.
CAUTION: Remove the power cable from the PSU prior to removing the PSU. Also, do not connect the power cable before you
insert the PSU in the chassis.
NOTE: To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC Power Ports, use an external surge
protection device (SPD) at the AC input of the router.
AC 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 S3048–
ON chassis.
NOTE: Ensure that you correctly install the PSU. When you install the PSU correctly, the power connector is on the right 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, Dell EMC
recommends installing the power supply in the rst slot (PSU1) and installing a blank plate in the second slot (PSU2).
1 Remove the PSU slot cover from the S3048-ON 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 PSU exposed PCB edge connector rst.
The PSU slot is keyed so that the PSU can only be fully inserted in one orientation.
Figure 12. PSU installation
When you install the PSU correctly, it snaps into place and is ushed with the back of the switch.
4 Plug in the appropriate AC three-prong power cord from the switch PSU to the external power source.
5 If you have a redundant PSU, repeat steps 1 through 4 above using the second PSU slot on the S3048-ON switch.
