Installing the Server into a Rack
Several different rack mounting kits are available, depending on whether you need 2-
post or 4-post mounting and whether you need 19-inch or 23-inch rack widths. Also
available are a basic slide rail kit and a rail enabling kit. For detailed information
about the rack mounting kits and how to order them, see the Carrier Grade Server
Configuration Guide. The latest version of the Configuration Guide is located on the
(search for CG2100, click on
Product Downloads, then Ordering Guide).
Installation instructions are included in each of the rack mounting kits.
Connecting the Power Cord
NOTE: When using a rack, wait to install the power cord(s) until after the server is
in the rack.
Equipment Rack Precautions
CAUTION: ANCHOR THE EQUIPMENT RACK — The equipment rack must be anchored to an
unmovable support to prevent it from falling over when one or more servers are
extended in front of it on slide assemblies. The equipment rack must be installed
according to the manufacturer’s instructions. You must also consider the weight of
any other device installed in the rack.
Mains power disconnect — The power cord(s) is considered the mains disconnect for the
server and must be readily accessible when installed. If the individual server power
cord(s) will not be readily accessible for disconnection then you are responsible for
installing a power disconnect for the entire rack unit. This main disconnect must be
readily accessible, and it must be labeled as controlling power to the entire rack,
not just to the server(s). To remove all power, two power cords must be removed.
Grounding the rack installation — To avoid the potential for an electrical shock
hazard, for AC power you must include a third wire safety ground conductor with the
rack installation. For DC power the two studs for chassis enclosure grounding must be
used for proper safety grounding. See “E” in Figure 6
for the location of the ground
studs. With AC power, if the server power cord is plugged into an outlet that is part
of the rack, then you must provide proper grounding for the rack itself. If the server
power cord is plugged into a wall outlet, the safety ground conductor in the power
cord provides proper grounding only for the server. You must provide additional,
proper grounding for the rack and other devices installed in it.
