1 Preparing for Installation
1.1 Audience
This guide is intended for HP service representatives and other persons trained to install hardware
options in the 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 or access specific manuals and guides from the CD that is shipped with
your HP Cluster Platform solution:
HP 10K Series Rack (Documentation
option):

Cluster Platform Gigabit Ethernet Interconnect Guide
1.3 Kit Description
The cable management brackets described in this manual are designed to align and support
cables that lead from an HP ProCurve 5406zl system interconnect to the PCI interface cards
installed in each server (node). The brackets provide strain relief, ensure the correct bend radius
for the cables, and provide cable routing and cable management.
1.4 Kit Contents
This kit contains the following components:
• The cable management brackets shown in Figure 1-1.

of the channels (right side shown).
Note:
The right bracket is shown in Figure 1-1. The left bracket (not shown) is exactly opposite
from the right bracket.
• The fasteners that are specified in Table 1-1.

To prevent screws from becoming loose due to vibration, HP recommends using an adjustable
torque driver set to the torque specifications shown in Table 1-1. Contact your HP sales
representative if any parts are missing.
1.5 Required Resources
To install the kit, you need the following resources:
• Tools:
— Screwdriver, #2 (medium) Phillips.
— Cage-nut insertion tool (shipped with the rack) or a flat-bladed screwdriver.
— Marker pen or masking tape.
• Resources: A sample cable of the type used by the system interconnect.
• Environment:
— A work surface adjacent to the rack.
— A stable work platform or step stool that lets you safely reach the servers installed in
the upper part of the rack.
10 Preparing for Installation

2 Installing the Cable Management Brackets
The location of the brackets depends on the rack position occupied by the interconnect. The
interconnect in an HP Cluster Platform solution is typically installed in the lower “U” locations
of the rack. To install the cable management brackets, follow these steps:
1. Determine the cable management brackets installation locations by aligning the cable
management bracket's mounting flange rack-mount holes with the flange rack-mount holes
in the mounting ears (see callout 6 in Figure 2-1) for the interconnect. Set aside the screws
that come with the interconnect mounting ears as they are not required for the cable
management brackets installation.
Note:
If the interconnect is already installed, remove the screws that hold the mounting ears to
the rear rails of the HP 10000 series rack one at a time, and then replace them one at a time
while mounting the cable management brackets as shown in Figure 2-1 using the M6 x 16
mm screws that come with the cable management brackets installation kit.
2. Fasten the cable management brackets to the rack's rear rails using two M6 x 16 mm screws
and two cage nuts for each cable management bracket. Sandwich the interconnect's mounting
ear brackets between the rack's rear rails and the cable management brackets (see Figure 2-1).
3. Tighten the four M6 x 16 mm screws to the recommended torque shown in Table 1-1
(page 10).
4. Route the cables through each of the corresponding channels as shown in Figure 2-2.

The following list describes the callouts shown in Figure 2-1:
1. ProCurve 5406zl interconnect
2. 10K rack right rear rail
3. M6 x 16 mm mounting screw (two for each side used with two cage nuts)
4. Cable management brackets
5. ProCurve 5406zl rackmount bracket (left side shown)
6. Left side ProCurve 5406zl interconnect mounting ear
Important:
The ProCurve 5406zl interconnect mounting ears are turned 180 degrees and point toward the
inside of the rack (see callout 6 in Figure 2-1). Installing the interconnect's rack mounting ears
this way will recess the interconnect chassis further into the rack and will allow more space for
cabling and cable management. HP recommends this installation procedure for the interconnect's
mounting ears when ProCurve 5406zl are selected along with CX4 modules for use in HP Cluster
Platform solutions.
2.1 Cable Routing Options
Figure 2-2 shows the cable routing options when the ProCurve 5406zl cable management brackets
are used.

2.2 Removing the Interconnect for Servicing
Bring the component to an appropriate state for removal, and put the rack cabinet into a safe
and stable state for component removal. You must ensure that you can reach the component
easily and handle it safely. Remove the interconnect as follows:
1. Switch off the power supply from the rack's power distribution unit and disconnect the
interconnect's power cable(s).
2. Disconnect and remove each network cable until all networking ports are unplugged. When
disconnecting the cables, ensure that you do not bend them more than the recommended
bend radius. The cable specifications are provided in the documentation for your cluster
type.
3. Remove the cable management brackets by reversing the installation procedure described
earlier in Chapter 2.
4. Slide the interconnect all the way out of the rack, as described in the documentation for the
interconnect rack kit.
