Pushbutton Locks and Configuration-Lock Jumper
The SVI II ESD offers several levels of accessibility. It may be desirable, after initial setup, to lock
the pushbuttons so that the SVI II ESD parameters cannot be inadvertently changed by the but-
tons. Several levels of pushbutton locks are provided and described in Table 7.
