Ac Or Dc Power Supply Installation; Dc Power Supply Connection - Dell EMC PowerSwitch Z9100–ON Installation Manual

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 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.

AC or DC power supply installation

NOTE: Do not mix AC and DC PSUs. Only use both AC PSUs or both DC PSUs in the same switch.
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 right
side of the PSU.
1. Remove the PSU blank from the Z9100-ON.
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 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.
