NetWare Card Numbers and Multiple Physical NICs

To connect a cable from the ATMLink NIC to the appropriate port on the ATM switch, you must know which physical NIC corresponds to a given NetWare card number.

All ATMLink LEC configurations include a card number that NetWare must correlate to a physical ATMLink NIC. LECs with the same card number are bound to the same physical NIC.

Using the ATMLink utility with the diagnostic utility is the quickest way to correlate physical NICs and NetWare card numbers. The diagnostic utility identifies each ATMLink NIC by MAC address and PCI slot number. The ATMLink utility identifies each NIC by the NetWare card number (NIC number) and the PCI slot number. Run the diagnostic utility to find out which ATMLink NICs are in which PCI slots. Then run the ATMLink utility to identify which card numbers are assigned to the NICs in the same PCI slots.

A more elaborate method to correlate physical NICs to PCI slot numbers is to observe the LEDs of the ATMLink NICs when the NetWare server is initialized.

When the first LEC is loaded, the driver correlates the card number with the first ATMLink NIC found on the PCI bus. When an LEC with a different card number is loaded, the driver correlates the new card number to the next ATMLink NIC found, and so on for all different card numbers detected. This process is repeated every time the server is booted.

As each LEC loads, the LED on the corresponding ATMLink NIC flashes slowly. In the sample AUTOEXEC.NCF file below, the LEC with card number 1 (cardnum=1) loads first, card number 3 loads second, and card number 2 loads third and fourth. Card number 4 is the fifth to load and is a standby NIC for card numbers 1, 2, and 3. The first ATMLink NIC found on the PCI bus is correlated to all LECs with card number 1, the second ATMLink NIC found is correlated to all LECs with card number 3, the third ATMLink NIC found is correlated to all LECs
