Power supplies
The switch ships with two AC or DC power supplies. The power supplies have two air-flow directions, normal and reverse.
Normal is from the I/O-side to the PSU-side. Reverse is from the PSU-side to the I/O-side.
Two PSUs are required for full redundancy, but the switch can operate with a single PSU.
The PSUs are field replaceable. When running with full redundancy—two power supplies installed and running, you can remove
and replace one PSU without disrupting traffic.
CAUTION: To prevent electrical shock, ensure that the Z9100-ON is grounded properly. If you do not ground
your equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that the power
cables meet your local electrical requirements.
NOTE: Connect the power supply to the appropriate branch circuit protection as defined by your local electrical codes.
Verify that the remote power source complies with the switch input power specifications.
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Use power supply 2 (PSU2) as the blank plate
slot. To install the blank plate, use a #1 Philips screwdriver.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the Z9100–ON and its components.

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.
