Integrity rx4640 Cable Bracket Installation Guide
To prevent screws from becoming loose due to vibration, HP recommends that you
use an adjustable torque driver set to the torque specifications given in Table 1-1.
Contact your HP sales representative if any parts are missing.
1.4 Bracket Overview and Features
A bracket is required for every server containing a PCI card that is connected to the
cluster’s interconnect. Depending on the type of interconnect, the cable diameter
might vary. This bracket kit supports cables that have a minimum diameter of
5/16-inch (7.9 mm) and a maximum diameter of 5/8-inch (15.9 mm). The bracket
supports the cable, providing strain relief for the PCI port and ensuring a good
connection. It also helps to ensure the correct bend radius for the cable. The
installation of a single bracket should take no more than 5 minutes to complete.
Figure 1-1 shows two views of the bracket and identifies features referenced in
the installation instructions.

The following parts are referenced in the installation procedure:
• Callout 1 shows the captive screw that you use to connect the bracket to the
server’s rail kit. The rail kit contains a threaded insert which accepts this
captive screw.
• Callouts 2 and 3 show the threaded inserts where you can mount the optional
8-inch or 13-inch straps. Use these straps to bundle cables as you route them
from the top of the rack to the bottom.
• Callout 4 shows the threaded insert where you mount the 3.5-inch strap. The
interconnect cable passes through this strap and connects to a socket in the
PCI card.
1.5 Resources
To install the kit, you require the following resources:
• Tools:
- A 6-inch long #2 (medium) Phillips (Posidrive or cross-point) screwdriver.
- A 6-inch long flat-bladed screwdriver.
• Environment:
- A work surface adjacent to the rack.
- The rack is tall, and you might not be able to work comfortably on the
topmost installations without a stable work platform or step stool.
