Inspecting Pins; Tools; To Inspect The Pins On The Rear Side Of The Midplane - Sun Microsystems Datacenter Switch 3456 Installation Manual

Inspecting Pins

Before installing the fabric cards and line cards, you must inspect the pins of the
midplane connectors. Inspection is a meticulous process, and cannot be hurried.
Expect about 30 minutes for each side of the midplane. To shorten this time, one
person might inspect the pins on the fabric card side (rear) of the midplane, while
another inspects the pins on the line card side (front) of the midplane.

Tools

For inspection, you need the following tools:
Pin gauge block
■
Bright flashlight
■
Magnifying glass or loupe
■
Notepad and pen

▼ To Inspect the Pins on the Rear Side of the Midplane

The primary tool used to check the midplane pins is the pin gauge block. This tool
effortlessly slides over the straight pins of an iTRAC connector that is in good
condition. If there is any resistance, a pin is bent and requires further examination.
1. Remove the rubber tubes that secure the filler strip for fabric card slot 0.
Set the tubes aside.
2. Remove the filler strip for slot 0.
Set the filler strip aside.
3. Using the pin gauge block, gently insert it into the iTRAC connector at the top.
4. If you feel any resistance to insertion, note the connector number on the
notepad.
