When cabling one or more of the module ports to a DTE device, you need to attach a
DTE-to-DCE adapter available from 3Com to the connector of each of the three cables
that is to connect to a DTE device. This procedure is described in "Cabling Instructions"
on .
You also must set the -PATH Service CLock parameter from External to Internal for the port
that you are connecting to a DTE device. Refer to the CLock parameter in the "Path Service
Parameters" chapter in the NETBuilder Family Bridge/Router Reference Guide for
instructions.
You can install up to three HSS RS-232 3-Port DTE/DCE modules at a time into a
NETBuilder II 4-Slot chassis and up to seven in an 8-Slot chassis.
You will need a small flat-blade screwdriver.
You can safely install a module without turning off or rebooting the NETBuilder II
system.
To install the module into a NETBuilder II 4- or 8-Slot chassis, follow these steps:
1 Remove the filler panel from the I/O slot you have selected.
You do not need to remove the cable strain-relief bracket that came with your
NETBuilder II chassis.
