Two-Post Installation; Two-Post Support Tray Kit - Dell PowerEdge 2550 Rack Installation Instructions

This installation guide provides instructions for trained service technicians installing one or
more Dell™ systems in a Dell rack. One rack kit is required for each system installed in the
rack. This guide includes procedures for two-post and four-post rack kits.
CAUTION: Do not attempt to install rack kit components designed for another
system. Use only the rack kit for your Dell system. Damage to the system and
personal injury may result.

Two-Post Installation

There are two types of two-post rack kits: a two-post support tray kit and a two-post
RapidRails™ rack kit. You can install each kit in a flush-mount or a center-mount
configuration.

Two-Post Support Tray Kit

The two-post support tray kit is used to install a Dell system in a two-post, open-frame relay
rack, such as those found in telecommunications equipment facilities. Both 3-inch and
6-inch wide two-post racks are accommodated. You can install this kit in a center-mount or
a flush-mount configuration.
You must properly secure the two-post rack to the floor, to the ceiling or upper wall, and
where applicable, to adjacent racks, using floor and wall fasteners and bracing specified or
approved by the rack manufacturer or by industry standards. See the rack manufacturer's
installation documentation for precautionary warnings before attempting this installation.
CAUTION: Do not attempt to install the system into a two-post, open-frame relay
rack that has not been securely anchored in place. Damage to the system and
personal injury may result.
See "Safety Instructions" at the front of this document for additional safety information
regarding rack installation.
