Check The Jumpers - 3Com 005687-03 Manual

Check the Jumpers

1. Touch an unpainted metal part of your
computer (the back is usually unpainted) to
discharge static electricity. Static can
damage your modem.
2. Take the modem out of its plastic bag.
3. Find the jumper shunts (small black plastic
pieces) on the COM port and IRQ jumper
pins on your modem. They should be in
roughly the area indicated in the following
illustration.

When doing a "Plug and Play" installation,
the jumper shunts should be placed so that
they are hanging from single jumper pins
rather than on pairs of pins. Your modem's
jumper shunts should already be in this Plug
and Play configuration. If they are not,
move them so they are hanging as in the
diagram on the next page.
