Procedure 6: Installing DEM’s V.24 Port
This procedure assumes that you have installed the DEM and want to install th
DEM’s optional V.24 port to provide the CX900e with a seventh port. If you have
installed or will install a Voice I/O Card, complete Procedure 7 before following
this procedure.
This procedure assumes that you have removed the cover from the chassis
(Procedure 2).
To install the DEM’s V.24 port:
1. If you have not already done so, confirm the DEM’s DTE/DCE configuration
after removing it from its slot. If necessary, unseat its jumpers, rotate them
180°, reseat them (as suggested in “Figure 4-2 DEM DTE/DCE
Configuration Jumpers” ), then return the DEM to its slot.
2. Remove the V.24 port knock-out on the chassis’ rear panel.
3. Push the the ribbon cable’s plug onto the DEM’s header at J1.
4. Fasten the ribbon cable’s DB-25 connector to the chassis’ rear panel.
