Connecting the power cord(s)

To connect the power cords, do the following:

Attention: Power connection must always be disconnected prior to removal of a

PSU from the system

1. Observe all safety and ESD precautions in the Safety and Warranty Guide.

2. Attach a power cord to the installed PSU. The Power On LED (see 1 in the

following figure) for the PSU will blink green when AC main power is present.

The Power On LED will illuminate a constant green when power to the PSU is

turned on.

Grounding checks

This product must only be connected to a power source with a safety electrical

ground connection.

DANGER

If more than one product is installed in a rack, the ground connection to the

rack is even more important because the rack will have a high “ground

leakage current” (“touch current”).

Prior to turning on power, ensure that the ground connection to the rack has been

checked by an electrical engineer qualified in local and national electrical

standards.
