X.25 PAD-2
4.2 Operating Instructions
After you install and plug in the X.25 PAD-2 as described
in
Chapter 3 , it normally operates unattended. Once
you configure the unit for your application as described
in the
Packet Switching Guide , it will store its configuration
settings in nonvolatile memory, so you shouldn’t need to
work with it again unless changes to your system require
it to be reconfigured. (This assumes that you can keep
jumper JP2 set to “NOR”; see
Section 3.3 .)
4.2.1 P
OWER
ON
Plug the power supply’s output cord into the barrel jack
on the front of the X.25 PAD-2. Then plug its input cord
into a working AC outlet. The PAD-2 should start
operating immediately—it doesn’t have an ON/OFF
switch—and the POWER LED on its top panel should
light.
If the synchronous packet-switched link on channel 1
isn’t yet operational, the SYNC LED on the PAD-2’s top
panel will flash. Wait until the link becomes operational
(up to a few seconds for X.25 or a minute for Frame
Relay); when it does, the SYNC LED will stop flashing
and become steadily lit.
