1.1 Audience

This guide is intended for HP service representatives and other persons trained to install hardware

options in HP 10000 series racks. Such persons are expected to understand the hazards of working

in this environment and to take suitable precautions to minimize danger to themselves and

others.

1.2 Documentation Resources

You can download the documentation for components referenced in this installation guide from

the following locations:

• HP 10000 Series Rack (Documentation option):

1.3 Kit Description

The HP DL1000 series cable management kit described in this manual is designed to align and

support the InfiniBand cables that lead from the server to another InfiniBand switch in the rack

or to an adjacent rack. The kit provides strain relief for the cables connected to the individual

InfiniBand connector ports and ensures a good connection. It also ensures the correct bend radius

for the InfiniBand cable and provides channels for cable routing and cable management. One

cable management kit is required for each HP ProLiant DL4x170h G6 server.

NOTE: The cable management kit is designed to support 24 AWG (0.41 inch) diameter, 26 AWG

(0.37 inch) diameter, and 28 AWG (0.33 inch) diameter InfiniBand cables. Consult the

documentation supplied with your cluster before installing the brackets and routing the cables.

1.4 Kit Contents

Verify that the cable management bracket kit contains the following components:

• Packaging and documentation.

• Four 3.5-inch Velcro straps

• The bracket hardware shown in Figure 1-1.

1.5 Required Resources 7

1.6 Prerequisites

Before you begin to mount the bracket:

•Follow the usual cable-handling precautions for InfiniBand cables, see the HP Cluster Platform

InfiniBand Interconnect Installation and User's Guide.

that came with your InfiniBand device.

• Obtain the set of cabling tables required for your HP Cluster Platform solution.

8 Preparing for Installation

2 Installing the Cable Management Kit

The location of the cable management kit depends on the rack position occupied by the server

chassis. Align each bracket with the InfiniBand connector ports on the server so that the bracket's

mounting flange is level with the InfiniBand ports.

2.1 Installing the Cable Management Kit

To install the cable management kit, follow these steps:

1. Identify and mark the two holes in the rack's rear mounting rails (callouts 1 and 3 in

Figure 2-1) and clip the 10-32 cage nuts (callout 4 in Figure 2-1) into the square holes.

2. Fasten the top and bottom brackets (callouts 2 and 6 in Figure 2-1) using the four 10-32

screws (callout 5 in Figure 2-1).

Figure 2-1 Installing the Cable Management Brackets

2.2 Securing the InfiniBand Cables

After installing the cable management brackets (callouts 1 and 2 in Figure 2-2) you must install

the Infiniband cables. Once the InfiniBand cables (callout 3 in Figure 2-2) are installed, you can

secure them to the cable management brackets using the 3.5-inch Velcro straps (see detailed view

in Figure 2-2).
