For information about the features of the HSS RS-232 3-Port DTE/DCE module, refer to Chapter 2. Before Installing To prepare to install the module into the NETBuilder II system, follow these steps: the Module 1 Observe appropriate electrostatic discharge (ESD) precautions.
Serial number example: S/N:1DN12345 MAC addresses example: 0800021A4B5C, 0800021A4B5D, 0800021A4B5E The MAC addresses are also encoded in the module EEPROM. Use the procedure in the NETBuilder II Base System Installation Guide to display the MAC addresses encoded in the EEPROM. Software/Hardware Verify that you have NETBuilder software version 7.2 or later and CEC firmware version...
Changing the Jumper Settings I f you change a port setting from DTE to DCE, you must set the -PATH Service CLock parameter from External to Internal for that port. Refer to the CLock parameter in the “Path Service Parameters” chapter in the NETBuilder Family Bridge/Router Reference Guide for instructions.
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.

(such as an IBM cluster controller or an IBM mainframe computer), you must first change the port’s jumper setting from DTE to DCE correctly as described in “Changing the Jumper Settings” , and attach a DTE-to-DCE adapter provided by 3Com to the corresponding cable connector.
CAUTION: Because of the weight of the 3-Port cable, use the strain-relief bracket to decrease the possibility of damage to the module. If the cable is too large to fit in the bracket along with other NETBuilder II module cables, use cable ties or other means of strain relief.
1-10 1: I HAPTER NSTALLATION CAUTION: When changing jumper settings on the module and when cabling the module to devices, be aware that when the RS-232 3-Port cable is connected to the module, the positioning of the three hydra cables carrying the port signals are not visually in a direct or expected line with the location of the jumpers on the module to which the signals correspond.
Signal Ground Signal Ground CAUTION: All interconnecting cables must be properly shielded to reduce the potential for interference. Only cables from 3Com are guaranteed to meet emissions standards. If other cables are used, 3Com cannot guarantee compliance. DTE-to-DCE Adapter Figure 1-5 lists the pin assignments for the DTE-to-DCE adapter.
