Manual Version: AP101-20110725 BOM: 3105A01M Part number: 5998-1959 HP X421 A-Series Chassis Universal 4-Post Rack Mounting Kit Installation Guide 1 Application scope An HP X421 A-series chassis universal 4-post rack mounting kit includes cage nuts, screws, and a pair of slide rails. The length of a slide rail is in the range from 500 mm (19.69 in) to 800 mm (31.50 in). Before using a slide rail, note the following guidelines: • The depth of the rack falls into the length range of the slide rail. • A set of slide rails can bear a weight of no more than 350 kg (771.60 lb). 2 Installation procedures NOTE: The installation of slide rails might vary with different types of racks. The following installation procedure is for your reference only. Follow these steps to install a slide rail: Step1 Read the signs on the slide rail (see Table 1) to avoid installation mistake.

F/R Front end of the right slide rail Mount this end to the front right rack post. Mark the position on the rack for installing the slide rail. • Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area between holes, as shown in Figure 2. • Each rack post requires six screws to fix the slide rail. You only need to mark the uppermost square hole and lowermost square hole for installation. • Mark the square holes at the same height on the other three rack posts. NOTE: One rack unit has three holes, the middle of which is an auxiliary installation hole, and the other two are standard installation holes. You can distinguish them by the space between each two holes. The space between a standard installation hole and an auxiliary installation hole is larger than that between two adjacent standard installation holes.

Figure 4 Fix the slide rail to the cage nuts with screws Step5 Keep the slide rail horizontally and adjust its length until the installation holes on the rear end of the slide rail touch the cage nuts on the rear rack post. Then fix them with screws. TIP: Fix all installation holes of the slide rail with screws to ensure its weight bearing capacity. Step6 Repeat Step4 and Step5 to install the other slide rail. Make sure the two slide rails are at the same height so that the device can be placed on them horizontally. Figure 5 shows the installed slide rails. iii Manual Version: AP101-20110725 BOM: 3105A01M Figure 5 Installed slide rails Copyright (c) 2010-2011 Hewlett-Packard Development Company, L.P. 59981959 iv Part number: 5998-1959
