Figure 16. Connecting AC Power Supply Cords

1. AC3 Prong

NOTE: The system is powered-up as soon as you connect the power cord between the system and the power

source.

CAUTION: Always disconnect the power cable before you service the power supply slots.

CAUTION: Use the power supply cord as the main disconnect device on the AC system. Ensure that the socket-

outlet is located/installed near the equipment and is easily accessible.

4. Repeat steps 1 through 3 above using the second PSU.

NOTE: Ensure that the PSU is correctly installed. When you correctly install the PSU, the power connector is on the left

side of the PSU.

Important Points to Remember for Installing a DC Power Supply

• When using DC power supply, peel o the DC electrical label and place it on the main regulatory label found on the bottom of the

S5000 chassis. Position this label over the AC electrical ratings within the dashed outline.

• The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the S5000 chassis.

• The S5000 supports AC and DC power supplies with two air-ow directions (I/O to Utility and Utility to I/O). The S5000 does

not support mixing PSU types, that is, you cannot replace an AC PSU with a DC PSU and an AC-R PSU with a DC-R PSU. The

fan airow direction for both the PSUs must be the same.

• For DC PSUs, the power status LED is on the upper-left corner.

• A DC PSU must be properly grounded. The system does not work when plugged into the wrong power source polarity.

• To view the log messages, use the show logging command. For more information, refer to the System Logs chapters of the

Dell Networking OS Command Line Reference Guide for the S5000 Switch and Dell Networking OS Conguration Guide for the

S5000 Switch.

WARNING: Although the switch can run on one PSU, Dell Networking highly recommends using two PSUs for full

redundancy and proper cooling. If the switch needs to run with only one PSU for a time, be sure to cover the second

PSU slot opening with a blank plate to avoid overheating.

WARNING: The Utility panel consists of four slots numbered from 0 to 3. Insert PSUs in slots 0 and 3.

WARNING: The PCB edge connector is at the bottom of the switch. Avoid installing the switch upside down.
