Cabling The Ethernet Module For Network Connection - 3Com NETBUILDER II Installation Manual

Cabling the Ethernet
Module for Network
Connection
4 Check that the connector/LED panel of the newly inserted module is flush with the
NETBuilder II chassis, and is aligned with the connector/LED panel(s) of any other
installed module(s) to verify that the board is seated correctly (see Figure 2-5).
5 Use your fingers to attach the two captive screws and tighten them "finger tight" only.
A solid connection of the I/O panel to the chassis is required for proper operation, but
the screws should not be used to force the board into place.
Figure 2-5 Ethernet Module Board Installed
When the module is inserted and secured in the slot, you are ready to attach the
cabling and connect the module to the network.
To cable and connect the Ethernet module, connect the appropriate network cable to
the appropriate Ethernet module connector, as illustrated in Figure 2-6 ( this cable is
not provided with the module).
CAUTION: To eliminate cable noise emission in excess of FCC regulations, Part 15,
subpart J, VDE specifications 0871, and specification CISPR22 (EN55022) for Class A
devices, all interconnection cables should be equipped with shielded connectors, the
backshells of which must completely surround the cable shield
The connector on the right as you are facing the connector/LED panel is the BNC thin
Ethernet cable connector. Connect one end of the cable to the Ethernet module with
the on-board transceiver and the other end to the thin cable.
CAUTION: The Ethernet module will not support thick and thin Ethernet connections
simultaneously. Do not attempt to connect both types of Ethernet cable to a single
module..
