6 Power supplies The Z9264F-ON switch ships with two AC or DC power supplies. The two PSUs 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. 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. The DC PSUs are rated -48 to -60VDC, 32A minimum, Tma=45°C, and 500m altitude operation. The user-supplied power cable must be 10AWG, 32A minimum, with a 60V minimum rating. CAUTION: To prevent electrical shock, ensure that the Z9264F-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: 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 Z9264F-ON switch and components.

Power supplies
The Z9264F-ON switch ships with two AC or DC power supplies.
The two PSUs 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.
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.
The DC PSUs are rated -48 to -60VDC, 32A minimum, Tma=45°C, and 500m altitude operation. The user-supplied power cable
must be 10AWG, 32A minimum, with a 60V minimum rating.
CAUTION:
To prevent electrical shock, ensure that the Z9264F-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:
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 Z9264F-ON switch and components.
