(callout 3).

5 Preparing for Installation

To install the kit, you require the following resources:
• Tools:
- A 6-inch long #1 (small) Phillips (Posidrive) screwdriver.
- A 6-inch long #2 (medium) Phillips (Posidrive) screwdriver.
- Cage-nut insertion tool (optional).
To prevent screws from becoming loose because of vibration, HP recommends
that you use an adjustable torque driver set to the torque specifications given
in Table 1.
• Environment:
- A work surface adjacent to the installation rack.
- A small work platform or stable stepladder or step stool.
- Personnel – HP recommends that two people are available to lift and install
the interconnect onto its rail.
6 Identifying the Installation Location
Each 1U rack location is numbered 01–42 from the bottom to the top and is marked
on the rack columns. At each rack location, there are three square mounting holes,
which are identified as top, middle, and bottom. A fastener location is specified as
10–middle, meaning the middle hole of rack position 10.
The installation location depends on the configuration rules for your cluster. (See
Section 2 for information about where you can obtain documentation resources).
Each component occupies a specific rack location so that the cabling is correct, and
the rack locations of each component are defined in the cluster documentation. For
ease of reference, mark the positions for fasteners with tape or a marker pen.
You can use this kit with both 3U and 5U Myrinet interconnects. The most common
location for these interconnects is at rack position 0, at the very bottom of the rack.
(This installation guide shows the interconnect installed at rack position 0, using
the 0–middle and 0–top mounting holes.)

7 Installing the Rail

Working from the rear of the rack, install the left rail as shown in Figure 3.
