Board Removal and Installation
This chapter gives an outline of how to remove and how to install a Sun 3400
CPU
board. As needed, refer also to Appendix B which contains much of the
detailed information and to the Sun 3400
CPU
Configuration Procedures manual.
If you are installing a new Sun system, skip this chapter. The Sun 3400
CPU
board is already installed. Instead, refer to the system installation manual that
came with your system and to Chapter 3 in this manual, which explains how to
connect cables to the Sun 3400
CPU
board.
Before reading anything else in this chapter, read all the cautions in this chapter.
There are quite a few. It is irn,portant that you understand and heed each one to
prevent inadvertent damage and downtime.
o
A 5/64-inch or 2mm Allen (hex) wrench to secure the
CPU
board's backplate
in the cardcage.
o
A screwdriver with a flat blade 1/8-inch wide for the screws that secure the
cables to the
CPU
board.
o
A pair of needle-nose pliers to remove or install jumpers on the
CPU
board.
o
An antistatic wrist strap attached to an earth ground location whenever you
handle the boards. This wrist strap is to conduct electrostatic charges (static
electricity) from your body to ground before these charges can damage com-
ponents on the
CPU
board.
o
A #2 Phillips screwdriver to remove/install the screws that secure the back-
plane access panel.
o
A large flat-blade screwdriver to help in opening the system enclosure.
The normal procedure for replacing a
CPU
board is to remove the old board,
remove selected chips from the board, return the board to Sun Customer Service,
obtain a replacement
CPU
board from Sun, inspect the replacement board, install
the removed chips on the replacement board, configure the replacement board,
and then install the board in the system.
