Setting The I/O Base Address - Cabletron Systems T2015 Installation Manual

Setting this jumper is described in Section 2.3.2. The jumper's
default setting is correct for most computers. Refer to Figure 2-1 for
the jumper and switch locations.
If your adapter is installed in a computer with incompatibilities
in the bus architecture, such as an IBM PS/2 Model 30-286,
NOTE:
you may need to change the bus compatibility switch in the
driver software command line. Setting this switch is described
in the Network Software Installation Guide.

2.3.1 Setting the I/O Base Address

Before the T2015 adapter can be used, the I/O base address must
be set using a pair of two-position dip switches accessible through
the card's bracket. The switches are located just below the ports on
the bracket (see Figure 2-2).
The card's other parameters are set during the installation of
network software. This configuration is discussed in the Network
Software Installation Manual.
The I/O base address is a hexadecimal field that distinguishes the
T2015 adapter from other adapters that may be in the PC. The
adapter must be set to one of four base addresses - 0A20, 0A80,
1A20, or 1A80.
The adapter is sensitive to static discharges. Hold the
! adapter by its corners. Avoid contact with the PC bus edge
connector or any of the components, except the jumpers.
CAUTION:
Failure to observe all static precautions may result in
damage to the adapter.
