The Z9332F-ON switch ships with two AC power supplies that support air-flow from the I/O to the PSU. From the PSU-side of the
switch, PSU1 is on the right side; PSU2 is on the left 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 Z9332F-ON switch 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:
PSU airflow must match the airflow direction of the fans. The fans ship preinstalled with airflow from the I/O to
the PSU. Optionally, you can order and install fans with airflow from the PSU to the I/O.
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 screw driver.
NOTE:
ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the Z9332F-ON switch and components.

NOTE:
DC power is not supported.
NOTE:
AC power requires HighLine 200–240 VAC support. Using 120 VAC does not provide adequate power for the
system.
Power supply 1 (PSU1) is on the left side of the switch; power supply 2 (PSU2) is on the right side of the switch.
1. PSUs
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.
