13.2.1.1 Card Jumper/Switch Settings
The FXO 2W*8-6 Card has eight sets of jumpers that you must set before inserting the card
into a system chassis. Figure 13-1 shows these jumpers, which allow you to configure
individual ports of the card for either FXO or MRD operation.
To set up a port for MRD operation, insert shorting jumpers vertically between pins 1 and 2
for that port, as shown. Each port has two associated jumpers. To use FXO operation on any
port, remove its associated jumpers.
Note that jumper position numbers 1 and 2 are not marked on the card. They are shown in
Figure 13-1 for your convenience.
