X.25 PAD-2
3.3 Setting the NOR/INI Jumper
Most of the X.25 PAD-2’s configuration settings are
handled through its command facility (refer to the
Packet Switching Guide ). There is, however, one jumper
inside the unit that you might want to set differently. As
shown in Figure 3-1 on the next page, the jumper is
labeled JP2 and has two possible settings: NOR (normal
operation) and INI (initialize).
If JP2 is set to NOR (the default setting, suitable for
most applications), the X.25 PAD-2 will begin operating
normally when you power it up, using the same
configuration settings that it was using when it was last
powered down.
If JP2 is set to INI, the X.25 PAD-2 will initialize itself,
restoring all of its configuration settings to their factory-
default values, every time you power it up.
To access this jumper, make sure the PAD-2 is
unplugged, then unscrew and remove the four screws at
the corners of the bottom of the unit. You should then
be able to lift off the top half of the X.25 PAD-2’s case.
When you’re finished, put the top half of the case back
on and refasten the screws (do
not overtighten them).
