Installing the SmartSwitch 9000 Module

2-8

 

The Reset Switch

 

The Reset switch is located under the top plastic tab as shown in Figure 2-5. 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. Momentarily pressing the switch restarts the module.

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