ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

Inspection and Handling Cautions:

Unpack and inspect the new I/O Data Cable Assembly before shutting down the server.
Verify that connector guide pins are perpendicular to the connector and are securely fastened.
Inspect signal pins to assure there are no bent pins or other damage.
Minimize all flexing and twisting of the new I/O Data Cable Assembly. Excessive flexing may internally damage weld points where cables are joined to the connector inside the cable assembly. Cable flexing may also break small gauge wires inside the assembly.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Note: This document provides only high level recommendations to better assure success of the I/O data cable replacement. The detailed procedures for removal and replacement of the cable must be consulted in the SPARC M5-32 and SPARC M6-32 Servers Service Manual located at: Sparc M5-32 Documentation . Make certain the latest version of the Service Manual is available. Detailed replacement steps with illustrations are provided. Do not conduct this procedure without the Service Manual.

Servicing the I/O Data Cable

This component is cold service only.
The factory description for this cable is “CABLE ASSY, I/O”.

Caution – This component must be serviced only by a trained service technician.

Remove an I/O Data Cable

1. Use a grounding strap to protect the equipment from ESD damage.
2. Unpack and inspect the connectors of the replacement cable. If a guide pin is bent or loose, return the cable and order another replacement cable.

NOTE: DO NOT TWIST THE CABLE!

Caution – Use an antistatic mat to protect the cable from ESD damage.

Caution – Avoid excessive bending of the cable. Repeated bending of the cable can break wiring to individual connector pins.

3. After the inspection, place the connector covers back on the connectors.
Do not discard the shipping package. You will use it to return the old cable.

4. Continue the cable removal steps as per the Service Manual procedure labeled 'Remove an I/O Data Cable'.

Caution – When removing an IO data cable watch for loose guide pins. There is a small risk some of the guide pins on the cable end may have become loose during original installation and could fall into the machine during removal. Make certain all guide pins are in place on the removed cable.

Install an I/O Data Cable

Caution – Minimize all flexing and twisting of the new I/O Data Cable Assembly during installation -- it may damage the cable.

1. Install the replacement cable as per the Service Manual procedure labeled 'Install an I/O Data Cable'. Heed all cautions and consult illustrations.
