Replacing a Power Supply

To replace a power supply, follow these steps:
NOTE: If a PSU fails, you must completely replace it. There are no field serviceable components in the PSU. To request a
replacement, see Dell Networking
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Dell Networking recommends using power supply
1 (PSU1) as the blank plate slot.
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 Disconnect the power cable from the failed PSU.
2 Push the orange lever to unlock the failed PSU and then use the grab handle to slide it out of the power supply bay.
3 Remove the replacement PSU from the electrostatic bag.
4 Insert the replacement 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.
5 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, you can defer this step until after the switch is installed in a rack and you
are ready to power up the system.

Installing a Fan Tray

To install a fan tray, follow these steps:
NOTE: The fan tray is hot-swappable.
1 Take the fan tray out of the shipping box.
2 Use the grab handle on the fan tray to slide it into the bay.
