Connecting The Power Cables - Sun Microsystems Sun Enterprise 10000 Hardware Installation

Connecting the Power Cables

The system requires an electrical circuit that is grounded to earth. The American
standards group, Underwriters Laboratories, Inc., specifies:
An insulated earth-ground conductor that is identical in size, insulation material,
and thickness to the earthed and unearthed branch-circuit supply conductors,
except that it is green with or without one or more yellow stripes, is to be
installed as part of the branch circuit that supplies the unit or system. The
earthing conductor described is to be connected to earth at the service equipment
or, if supplied by a separately derived system, at the supply transformer or
motor-generator set.
The attachment-plug receptacles in the vicinity of the unit or system are all to be
of an earthing type, and the earthing conductors serving these receptacles are to
be connected to earth at the service equipment.
Caution – The AC power connections provide a ground path that will protect the
components (boards and drives) in the cabinet from static electricity damage.
Complete the following connections with the power cables provided.
1. Unpack and place the SSP on the customer-supplied table.
2. Verify the power switch is in the off position.
3. Verify with a digital voltmeter (DVM) that the incoming AC voltage is correct.
Refer to the Sun Enterprise 10000 System Site Planning Guide for further information.
4. Using the power cables provided, connect the SSP to the customer-supplied power
receptacles.
5. Secure all cables to improve overall appearance and prevent damage.
