servicing the system. It also lists the tools and equipment you will need.
1.1 Safety Precautions
For your protection, observe the following safety precautions when setting up your
equipment:
■ Follow all cautions, warnings, and instructions marked on the equipment.
■ Never push objects of any kind through openings in the equipment as they may
touch dangerous voltage points or short out components that could result in fire
or electric shock.
■ Refer servicing of equipment to qualified personnel.
To protect both yourself and the equipment, observe the following safety
precautions:

1.4 Filler Boards and Filler Panels
Filler boards and panels, which are physically inserted into the board or card slot,
are used for EMI protection and for air flow.
TABLE 1-3 describes the precautions you must take when you remove boards or
assemblies from a system in order to prevent the system from overheating.
TABLE 1-3 Overheating Precautions Using Filler Boards
If you have... Do the following
Empty PCI card slots Install PCI filler boards in all empty PCI card slots.

overheating if the system is to be operating without the CPU/
Memory board installed. If two CPU/Memory boards must be
removed, use a CPU filler panel over one board slot and install a
filler board in the second board slot in order to prevent the system
from overheating. Do not install two filler panels.
A filler board occupies the empty slot for one of the System
Controller boards. If you install a redundant System Controller
board, remove the System Controller filler board.
Install power supply filler panels in empty power supply slots
within one minute in a powered-on system.
1.5 Tools Required
For the procedures in this document, you will need these tools:
■ Screwdriver, Phillips #2
■ Screwdriver, Phillips #2 with six-inch shank
■ Needlenose pliers
■ ESD mat
■ ESD grounding wrist strap or foot strap

Powering Off and On
This chapter describes how to power the system off and on. These systems do not
have a physical keyswitch. To power off the system, you must halt the Solaris
Operating Environment in each domain and then power off the domain.
2.1 Powering Off the System
Refer to the Sun Fire 6800/4810/4800/3800 Systems Platform Administration Manual for
complete step-by-step commands for powering off the domains and the system.
1. If your Sun Fire 4810/4800/3800 system is not in a Sun Fire cabinet, skip this step.
For Sun Fire 6800 system or Sun Fire 4810/4800/3800 systems mounted in a Sun
Fire cabinet, turn the keyswitch on the FrameManager to the off position
(
FIGURE 2-1).
