Linux Clusters QsNetII Cable Management Kit Installation Guide

• Eight cable management bars, identified by callout 1 in Figure 1. Each bar
provides 16 cable hooks. There is a spring-loaded retainer pin at the top of each
bar, identified by callout 2 in Figure 1.
• Two rear bar brackets, which stand off the rear rack columns and are identified
as follows:
- An upper rear bracket, which provides four retainer holes for the
spring-loaded pins at the top of each bar. This bracket is identified by
callout 3 in Figure 1.
- A lower rear bracket, which provides four pairs of mounting lugs for each
cable management bar. This bracket is identified by callout 4 in Figure 1.
• Two front bar brackets, which are inset between the front rack columns and are
identified as follows:
- An upper front bracket, which provides four retainer holes for the
spring-loaded pins at the top of each bar. This bracket is identified by
callout 5 in Figure 1.
- A lower front bracket, which provides four pairs of mounting lugs for each
cable management bar. This bracket is identified by callout 6 in Figure 1.
• A cable guide plate that you attach to the frame at the rear of the rack (not the
rack columns) and provides a routing guide and support for cable bundles.
This guide plate is required only for interconnects installed into the upper
part of the rack.
• Eighteen straps with hook-and-loop closures, which are supplied with the cable
guide plate to secure the cable bundles. There are 9 short straps and 9 long
straps that you use depending on the diameter of the cable bundle.
• Table 1 specifies the fasteners included in the kit.
