Install the S6000 | 29
Installing an AC or DC Power Supply
The S6000 supports two hot-swappable PSUs with integrated fans that provide cooling for the system.
The S6000 supports AC and DC power supplies with two air-flow directions (I/O to PSU or PSU to I/O).
Two PSUs are required for full redundancy, but the system will operate with a single PSU.
NOTE: S6000 ships with two PSUs. However, it is possible to run the unit with a single PSU. If you use a
single PSU, install a blank plate in the other PSU slot. Dell Networking 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 S6000 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: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or
heel ground strap when handling the S6000 and its components.
CAUTION: To prevent electrical shock, ensure the S6000 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.

NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this may damage the PSU or
the S6000 chassis.
NOTE: Ensure that the PSU is correctly installed. When the PSU is correctly installed, the power connector is
on the right side of the PSU and the status LED is at the bottom of the PSU.

Cut the cable to the desired length. The cable length must facilitate proper operation of the fault interrupt circuits.
Dell Networking recommends using of the shortest cable route allowable.
3
Attach the one-hole lug to the chassis using the supplied 10-32 screw with the captive internal tooth lock washer.
Torque the screw to 20 in-lbs.
4
Attach the other end of the ground cable to a suitable ground point. The rack installation ears are not a suitable
grounding point.
