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.

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 off 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-flow 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 airflow 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.
