This document describes how to perform visual inspection of board sockets and Centerplane pins to verify physical damage.
Inspecting for bent pins or socket damage involved the removal and close examination of System Board's (SB), I/O Boards (IB), or even Repeaters (RPs) on Sun Fire[TM] Midrange Servers. For this reason, only Oracle badged service personnel should investigate a potential bent pin or socket issue in the field - NOT the customer.
This document provides general advice in how to perform the visual inspection and provides photos of actual pin and socket damage that has been encountered in the field. Use this as a reference as it will help show what to look for as trying to determine if a pin is bent or a socket is damaged.
Please raise a SR to Oracle Support in order to have Oracle badged personnel to go through the needed steps.
Basic Pin and Socket Information
- Pins are located on the Centerplane (CP) on Sun Fire[TM] Midrange Servers.
- Pins are tightly organized in rows and columns.
- Pins can become bent if they are even slightly misalligned and then a board is inserted into the slot.
- It is difficult to impossible to see these pins simply by looking into a single empty board slot.
- Sockets are located on the boards inserted into Sun Fire[TM] Midrange Server chassis.
- Sockets are tightly organized in rows and columns to allign with the CP pins.
- Socket holes are square in shape when undamaged.
- They are easily examined when the board is removed from the chassis.
