Sun Microsystems 220R manual Install any optional drive shipped with your system

2.Install any optional drive shipped with your system.

Many of the options ordered with your system may have been pre-installed at the factory. For information about how to install other options, see the Sun Enterprise 220R Server Service Manual or contact your qualified service provider. However, if you ordered a second internal disk drive that was not factory-installed, see the section:

■ “How to Install a Disk Drive” on page 95

Note –To install any additional options, contact your qualified service provider.

3.Install the system into the rack.

The server is shipped with inner glides attached. See “About Server Rackmounting” on page 18 and the Sun Enterprise 220R Server Setup and Rackmounting Guide accompanying your system for installation instructions for the rack. If the system’s slide assembly rails are already mounted in a rack, see “How to Place the System Into the Rack” on page 23.

4.Ensure that the system’s front panel keyswitch is in the Standby position. See “About the Status and Control Panel” on page 7.

5.Once the system is installed in the rack, connect the AC power cord to the power inlet labelled (1) at the back of the system. Use a strain relief (if necessary), and connect the other end of the cord to a grounded AC power outlet.

To prevent accidental or inadvertent removal of an AC power cord from its inlet use the strain relief. The strain relief is a plastic tie-wrap and pedestal that is inserted into the back panel of the system. Use these reliefs to manage the power cords after you have installed the cords into the AC inlets in the server.

■To use a strain relief, wrap the loose end of the tie-wrap around the AC power cord and thread the tie-wrap through the opening in the relief pedestal.

Pull the end to tighten the tie-wrap.

■To release the AC power cord, lift up the tab on the relief pedestal and loosen the tie-wrap.
