The Reset Switch

The Reset switch is located on the front panel, under the top plastic tab as shown
in Figure 2-3. It serves two functions:

•

Pressing the reset switch twice within three seconds causes the processor (i960)
to reset.

•

Pressing and holding the switch on for three or more seconds causes the
module to shutdown. Pressing and holding the switch again for three seconds
restarts the module.

SNMP management may be used to disable this switch to enhance module
security.
