Dell EMC Z9264F-ON - Power Supplies; PSU Components and LEDs

Power supplies
The Z9264F-ON switch ships with two AC or DC power supplies.
The two PSUs have two air-ow 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 eld replaceable. When running with full redundancy—two power supplies installed and running—you can remove and
replace one PSU without disrupting trac.
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 qualied electrician to ensure that the power cables meet your local
electrical requirements.
NOTE: Connect the power supply to the appropriate branch circuit protection as dened by your local electrical codes. Verify
that the remote power source complies with the switch input power specications.
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.
