Installing Multiple Adapters
All users: The adapter’s 12-digit, hexadecimal Ethernet address is on a
sticker near the edge of the adapter. The Ethernet address is sometimes called
the node address or the MAC address. Note that the PCI slot number may not
correspond with the physical connector in your computer.
NetWare users: The server drivers use the PCI slot number to identify each
installed adapter. You can correlate the PCI slot number to the adapter by
using the Ethernet address that is printed on a label on the adapter. Run Setup
from the Intel disk to view the Ethernet address and slot number for each
installed adapter. For more information, see the README files. NetWare 4.11
server installations use unique slot numbers that are assigned during sever
setup.
Windows NT and Windows 95 users: Repeat the configuration procedure
for each adapter you want to install (add only one adapter at a time). While
PROSet can detect all the PRO/100B adapters in your computer, you still
need to perform the configuration process on each adapter. In Windows NT,
be sure to click the Show all PRO Adapters box in the Configuration window.
See the README file for more information.
Duplex Mode (10 Mbps only)
Duplexing is a performance option that lets you choose how the adapter sends
and receives data packets over the network. The PRO/100B T4 adapter can
operate at full duplex at 10 Mbps only, and when connected to a full duplex
10Base-T switching hub. At 100 Mbps, the PRO/100 T4 adapter operates at
half duplex only. To summarize:
• Full duplex (requires a 10Base-T full duplex switching hub). The
adapter can send and receive packets at the same time. This mode can
increase adapter performance capability. If the full duplex hub provides
auto-negotiation, the adapter runs at full duplex. If the full duplex hub
does not provide auto-negotiation, you need to set the adapter duplex
mode manually (see following paragraphs)
• Half duplex. The adapter performs one operation at a time; it either
sends or receives.
If your hub is running at 100 Mbps and half duplex, your potential
bandwidth is higher than if you run at 10 Mbps and full duplex.
