3. Installation

!
CAUTION
During all of this installation process, make sure that power to
your system is OFF.
The EPC-5A is not designed to be inserted or removed while the chassis is
powered up.

CAUTION
Make sure that the installation process described here is
performed in a static-free environment.
Do not remove any modules from their anti-static bags unless you are in a static-free
environment. The EPC-5A module, like most other electronic devices, is susceptible
to electrostatic discharge (ESD) damage. ESD damage is not always immediately ob-
vious. It can cause a partial breakdown in semiconductor devices that might not result
in immediate failure.

CAUTION
The EXP-MX mass storage module contains a delicate hard
disk. Use care during installation.
Subplane Installation
Subplanes are printed-circuit boards with connectors on both sides. A subplane
provides several functions. Primarily it acts as the PC/AT bus. Additionally, it
provides power from the VMEbus backplane to the EPC-5A and expansion modules.
How subplanes function is discussed in detail in Chapter 5, Theory of Operation.
Locate the appropriate subsection for the subplane you are using either by name or
by picture. Follow the directions in the appropriate subsection. A small bag of bolts,
nylon washers, and nuts is provided for optionally securing the subplane to the VME
backplane. If these are used, be careful not to over tighten the bolts. Over-tightening
causes the subplane to bend and may cause EXM failure due to poor contact.
