18 SVM2608 Introduction
PHYSICAL DESCRIPTION
The SVM2608 has a protective coating applied to it to ensure that the effects of environmental
hazards are minimized. This coating endows the modules with resistance to salt sprays, moisture,
dust, sand, and explosive environments, as the polymer coating provides a hermetic seal. The
module is designed to withstand the stress and rigors of shock and vibration, allowing the module
to be deployed in a variety of applications without concern for damage due to the surrounding
physical environment. The following table details the environmental specifications of this
module.

The SVM2608 has two indicator LEDs located on its front panel. The A/E (Access/Error) LED
flashes green when read/write commands are being sent to the module. Should the SVM2608
receive an error, the LED glows red. This LED can be overridden by the user by setting the Sysfail
bit in the
Reset, Sys Fail Control, Interrupt Levels Register. The P/F (Power/Fail) LED glows
green indicates the status of a processor driven self-test. If the self-test is successful, the P/F LED
glows green, if the test fails, however, the LED will glow red. Both the A/E and P/F LEDs can be
programmed to glow red when a fail condition occurs.
