PSU 1 and 2
The PSUs have an integrated fan, which you cannot replace individually; if the fan integrated in a PSU
fails, you must replace the entire PSU. You can replace the fan trays individually. For fan tray replacement
procedures, see Fans.
WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate
this system 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 or DC
Power Ports, use an external surge protection device (SPD) at the AC or DC input of the router.

Installing an AC or DC Power Supply

To install an AC or DC power supply, follow these steps.
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 Z9100–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 recommends installing the power supply in the first slot (PSU1) and installing a
blank plate in the second slot (PSU2).
1.
Remove the PSU slot cover from the Z9100-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 first).
The PSU slot is keyed so that the PSU can only be fully inserted in one orientation.
