Dell S3100 Series Getting Started Manual
NOTE: The PSU slides into the slot smoothly. Do not force the PSU into a slot as this may damage
the PSU or the chassis. Ensure that you install the PSU correctly. When you install the PSU correctly,
the power connector is on the right side of the PSU.
NOTE: The PSUs are field replaceable. When running with full redundancy (two power supplies
installed and running), you can remove and replace one PSU while the other PSU is running, without
disrupting traffic.
1.
Remove the PSU slot cover from the PSU side of switch. You can select either of the two PSU slots,
however, if you are using a single PSU, Dell Networking recommends using power supply 1 (PSU1) as
the blank plate slot.
2.
Remove the PSU from the electrostatic bag.
3.
Insert the PSU into the switch PSU slot (insert the PSU-exposed PCB edge connector first). The PSU
slot is keyed such that the PSU can only be fully inserted in one orientation.
4.
Plug in the AC cord from the switch PSU to the external power source, such as an AC wall outlet.
NOTE: The system powers up as soon as the cables are connected between the power supply
and the power source. If you have not yet installed the switch in a rack, defer this step until you
are ready to power up the system.
5.
If you have a redundant PSU (a second PSU), repeat steps 1 through 5 using the second PSU slot on
the S3100 series system.
6.
If you use a single PSU, install a blank plate in the other PSU slot.

3.
