Rackmount Rail Kit; Installing The Model 106 Enclosure - IBM 106 Hardware Installation And Maintenance Manual

Rackmount rail kit

Rack mounting rails are developed for use the Model 106 enclosure that installs into 1.2 m rack cabinets.
These rails have been designed and tested for the maximum enclosure weight, and to ensure that
multiple enclosures may be installed without loss of space within the rack. Use the rail kit and mounting
hardware provided by IBM.

Installing the Model 106 enclosure

Enclosure installation involves interrelated steps and product-kit subassemblies.
The rail kit comprises left and right rail subassemblies that attach to the Model 106 enclosure and the
rack. The cable management arm (CMA) comprises subassemblies that attach to the Model 106
enclosure, rails, and rack.
Warning: Do not attempt to install the enclosure into the rack with disks preloaded into drive
slots. Unload disks (if installed) and CRU modules to a static-protected area, and label them.
Failure to heed this Warning and the following guidelines could result in serious injury. Although
you can further lighten the enclosure by removing CRUs, it is not necessary to do so.
This procedure describes adjustment and installation of left and right rail subassemblies, followed by
installing the Model 106 enclosure into the rack.
1. Measure the rail-span depth distance from rear rack post to front rack post, and record this
dimension.
2. Take the left outer rail subassembly in hand; then rotate the middle slide release, and fully extend
the middle slide.
