NSTALLATION
This chapter describes how to install the HSS RS-232 3-Port DTE/DCE module into the
NETBuilder II® system and includes the following procedures:
Preparing for installation
Changing the module jumper settings if connecting one or more of the cable
connectors to data terminal equipment (DTE)
Installing the module in a NETBuilder II 4- or 8-Slot chassis
Installing the module in a NETBuilder II 8-Slot Extended chassis
Cabling the module
You must have NETBuilder software version 7.2 or later and CEC firmware version 2.1 or
later to use the module. If you want to change a port from DTE to data communication
equipment (DCE), you must have NETBuilder software version 9.1 or later.
In order to use the module with DTE devices, you must order an adapter kit (3C6044)
that contains three DTE-to-DCE adapters.
For information about the features of the HSS RS-232 3-Port DTE/DCE module, refer to
Chapter 2.
To prepare to install the module into the NETBuilder II system, follow these steps:
1 Observe appropriate electrostatic discharge (ESD) precautions.
ESD can damage circuit board components. Failures resulting from ESD may not be
covered under your warranty. To prevent this, follow these handling procedures:
Keep the module in its antistatic shielded bag until you are ready to install.
Do not touch pins, leads, or solder connections on the module.
Handle the module by the edges only.
Store or ship the module in static-protective packaging.
Observe proper grounding techniques when handling the module: use a foot strap
and grounded mat, or wear a grounded static discharge wrist strap.
