You have completed the installation of the two-post support tray rack. Two-Post RapidRails Kit The two-post RapidRails rack 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 centermount or a flush-mount configuration. The kit incorporates slide assemblies, which enable the system to be pulled out of the rack cabinet for servicing. You must properly secure the two-post, open-frame relay rack to the floor, 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 two-post, open-frame relay 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.
