Address Range Switches - IBM RT PC Options Installation

Address Range Switches

The address switches are set for operation of one adapter in a
system. If you install more than one adapter, you must set the
address switches. Likewise, if you are adding adapters to a system
that already has one or more asynchronous adapters installed, you
must remove the installed adapters and set the address switches as
shown below.
Use an opened paper clip or a ball-point pen to set the address
switches.
Installing: You can install either 4-port adapter in adapter slot
2, 4, 5, 7, or 8 in IBM 6150 and in slot 2, 3, 4, or 5 in IBM 6151,
whichever is available. See the system unit diagram for the correct
adapter slot.
