Service manual

The <REFERENCE>(XRP) module must be handled carefully. Figure 4–9
shows the proper way to hold the module. Be sure your hands do not touch
any components, leads, or XMI fingers. When inserting it in or removing
it from the XMI card cage, grasp the module only at the spot shown in
Figure 4–10, avoiding any contact with the 25 mil leads. Do not use any
component as a handle.
To avoid damaging the <REFERENCE>(XRP) module, follow these
handling procedures:
1. Always wear an antistatic wrist strap.
2. Before removing the module from its ESD box, place the box on a clean,
stable surface.
Be sure the box will not slide or fall. Never place the box on the floor.
And be sure no tools, papers, manuals, or anything else that might
damage the module are near it. Some components on this module can
be damaged by a 600-volt static charge; paper, for example, can carry
a charge of 1000 volts.
3. Hold the module only by the edges, as shown in Figure 4–9.
Do not hold the module so that your fingers touch any components or
leads. Be sure you do not bend the module as you are holding it.
4. Be sure nothing touches the module surface or any of its components.
If anything touches the module, components or leads can be damaged.
This includes the antistatic wrist strap, clothing, jewelry, cables,
components on other modules, and anything in the work area (such
as tools, manuals, or loose papers).
Remove your jacket and roll up your sleeves before handling the module.
Also remove any jewelry.
