Power supplies

The S4048–ON ships with one AC power supply. Dell recommends purchasing a second power supply.

The S4048–ON supports AC power supplies with 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. Two PSUs are required for full redundancy, but the system can operate with a single PSU.

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.

NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Dell Networking recommends using power supply 2

(PSU2) as the blank plate slot.

NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when

handling the S4048–ON and its components.

CAUTION: To prevent electrical shock, ensure that the S4048-ON 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.
