Standard Racks

Your standard HP Rack System/E is a welded steel frame with a removable rear door, casters, side panels,
leveling feet, and an anti-tip feet. Figure 2-1 shows how two basic racks might look tied together. The top
is 11-gauge, cold rolled steel. The base is 11-gauge, cold rolled steel. Threaded grounding connections are
provided near two columns at the base, and another at the top, rear.
Racks heights are measured in meters, inches, EIA units, and "U." 1 EIA unit equals 1 U, which equals
44.45mm (1.75 in). The columns are numbered EIA units. The U41 rack is 1.96m, or 41 EIA units.
Internally, rails and slides that hold your equipment lock into slots in the vertical mounting columns and are
sometimes fastened to the columns with screws. Column faces are numbered for easy placement of equip-
ment. An extendable top adds 8U of height. Tie-together kits allow easy, secure mating of 1.96m cabinets.
Tied together racks with the accessories are shown in Figure 2-2.
