Figure 10: Jumper location on short range optical modem
The jumpers are accessible after the modem has been pulled out. This is done by first
removing all green 18-pin connectors at the back, then remove all screws holding the
back plate. After the back plate has been removed the modem can be pulled out.
Note!
Only pull out the modem not the whole double size Euro-card. After the jumper settings
has been changed put everything back in reverse order.
Note!
All electronic are sensitive to electrostatic discharge. Proper action must be taken at
the work place to avoid electrostatic discharge!
