Power Supplies; Components - Dell S4810 Installing Manual

Power Supplies

The S4810 supports two hot-swappable power supplies units (PSUs) with integrated fans that provide
cooling for the system. The S4810 supports AC power supplies with two air-flow directions (normal and
reversed). Two PSUs are required for full redundancy, but the system will operate with a single PSU.
NOTE: If you use a single PSU, you must install a blank plate in the other PSU slot. Dell Force10
.
recommends using power supply 1 (PSU1) as the blank plate slot.
The PSUs are field replaceable. When running with full redundancy (two power supplies installed and
running), you can remove and replace one PSU while the other PSU is running without disrupting traffic.
The S4810 does not support mixing PSU types. You cannot replace an AC PSU with a DC PSU and you
cannot replace an AC-R PSU with a DC-R PSU.
WARNING: Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear
.
an ESD-preventive wrist or heel ground strap when handling the S4810 and its components.
CAUTION: To prevent electrical shock, ensure the S4810 is grounded properly. If you do not ground your
.
equipment correctly, excessive emissions may result. Use a qualified electrician to ensure the power cables
meet your local electrical requirements.
