Before removing any replacement or upgrade subassembly from its antistatic
bag, place one hand firmly on an unpainted surface of the chassis, and at the
same time, pick up the replacement or upgrade subassembly while it is still
sealed in the antistatic bag. Once you have done this,
do not
move around the
room or contact other furnishings, personnel, or surfaces until you have installed
and
secured
the subassembly in the equipment.
•
Remove the subassembly from the antistatic bag, handling printedĆcircuit boards
by the edges. Avoid touching components and circuits on a printedĆcircuit board.
•
If you must move around the room or touch other surfaces before securing the
subassembly in the equipment, first place the subassembly back in the antistatic
bag. When you are ready again to install the subassembly repeat these
procedures.
•
Order an ESD kit for the next time you need to add or remove a cover or panel.
You can order an ESD kit from Data General.
Installing Board Jumpers and Setting
Switches
When you install new or replacement devices in your system, you often need to specify
configuration parameters by setting jumpers and/or switches on the individual
devices. This section explains how to physically change the jumper and switch settings
on boards and drives. These guidelines apply to SCSI device configuration as described
in Chapters 4 and 7, and at various points throughout the succeeding chapters of this
manual.
Before you begin configuring a device, you will need the following:
•
A thorough understanding of the section Avoiding Electrostatic Discharge (ESD)
Damage" in this chapter
•
The device-specific technical manual for your option that shows the location of the
jumpers and switches
•
Nonmagnetic needlenose pliers
•
Nonmagnetic jeweler's screwdriver or another small-pointed device (such as a ball
point pen or paper clip end) to push DIP switches.
Installing Jumpers
Jumpers
, or jumper plugs, are small removable plastic posts that contain wire circuit
connectors.
Jumper pins
are rows of small metal posts sticking out from the board
surface. Figure 6Ć3 shows a row of jumpered and unjumpered jumper pins.
CAUTION: Youcan ruin the entire device by bending or breaking these delicate pins;
excercise extreme care when installing or removing jumper plugs.
