This dialog box is used to select the resources to be used by the Cabletron T2015 adapter.  If the adapter resources you select conflict with the systems, the network adapter may fail to start.  Please select any of the following, to learn more about each resource:

IRQ Level

I/O Port

DMA Channel

Max Frame Size

Transceiver

Line Speed

Timing

Alt Network Address


I/O Port

Select the beginning of the I/O port range to be used by the network adapter, the I/O port range cannot be used by another device in your system.  The I/O ports used by the network adapter will start at the I/O port you select and the next 16 I/O ports.


Base Address

Select the beginning of the base address range to be used by the network adapter, the base address range cannot be used by another device in your system.  The memory addresses used by the network adapter will start at the base address you select and the next 2K of memory.


Transceiver

Select the transceiver (media) you would like to use.  The primary transceiver (top media port) is shielded twisted pair (STP), while the secondary transceiver (bottom media port) is unshielded twisted pair (UTP).


IRQ Level

Select the interrupt to be used by the network adapter, this interrupt cannot be used by another device in your system.  Interrupts usually already in use by your system include interrupt 4 for COM1,  interrupt 6 for the floppy disk controller,  interrupt 7 for LPT1,  and interrupt 14 for the fixed-disk controller.


Alt Network Address

If you dont wish to use the burned-in network address (default), enter the new address here.  The network address is hexadecimal and entered in the following format: xx-xx-xx-xx-xx-xx


Max Frame Size

Normally you would not change the maximum frame size from its default unless required by certain services on your network.


Line Speed

Token-Ring can run at two different ring speeds, 4 or 16 Mbps.  You need to ask your network manager for the correct speed to run the network adapter.


Timing

Do not change from the default setting unless ask to do so by Cabletron tech support.


DMA Channel

Select a free DMA channel for your network adapter.
