Install Guide

1 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 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 rst.
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 ushed with the back of the switch.
