Introduction
There are two models of 3Com's 16-bit EtherLink 16 card: the 3C507, and the 3C507TP.
Both cards are 16-bit network interface cards recommended for CNS and ISA PC-based
servers; both cards are supported by VINES 4.11(5), but neither is supported by VINES
5.00(5). (The 32-bit Racal InterLAN card is recommended for EISA-based servers. See the
C&TS Products and Services catalog for details).
The 3C507 contains a BNC connector for coaxial connection to thinnet networks and an AUI
for connection to an external transceiver; the 3C507TP has a built-in 10BASE-T transceiver
with an RJ-45 jack for direct connection to twisted-pair: you'll need a TPAU to connect the
3C507 to TTP (telephone twisted-pair), but you don't for the 3C507TP.
Before installing either card in your server (or workstation), please note these important
considerations:
You must know both the hub type and mode (10BASE-T or Draft D) of the LAN to which
you'll be connecting before the card's network-related settings can be properly made; and
Because of a special addressing scheme used by 3Com, no other card in the server or
workstation can use I/O address 100.
This tutorial provides information about all these issues and includes configuration settings
for the Banyan ICA card, which uses I/O address 100 by default. Refer to Figure 1 or the list
below for an overview of the process. You may wish to leave your existing LAN card in place
in case you encounter problems installing the 3C507; you can remove the existing card at a
later date.
