I/O Address
Each QL 3222 board has a Mode Switch (DIP switch SW2). Positions 1 and 2 select the base I/O address used by the server driver to communicate with the QL 3000 processors. The QL interface requires eight consecutive I/O ports beginning with the base I/O address.
The I/O addresses selected must not be assigned to any non QL 3000 Series devices installed in the file server or bridge hosting the QL 3000 Series boards. However, all of the QL 3000 Series boards installed in this host should have the same base I/O address.
Reset on Loss of DCD or DSR
The QL 3222 is typically connected via the COM1 port to a modem performing remote communications over a telephone line. The COM1 port monitors the state of the Data Carrier Detect (DCD) or Data Set Ready (DSR) signals coming from the modem. The QL processors can be configured to perform an automatic hardware reset if DCD or DSR is dropped.
One practical usage of this feature is to force the QL processor to reset between remote sessions. This ensures users that they are connecting to a newly initialized system. It also verifies that users are properly disconnected from the network when their session terminates (i.e., a user will not remain logged into NetWare after "hanging up" the phone).
Depending upon the system configuration, either DCD or DSR will indicate that the telephone signal connection is established and that the modem is ready. Most configurations support DCD. However, if a multiplexer is installed between the QL 3222 COM1 port and the modem, it may be necessary to monitor DSR instead. Refer to the multiplexer manufacturer's documentation for this information.
The Mode Switch (DIP switch SW2) on the QL 3222 configures this feature.

Each node on a Novell network must be identified by a unique address. This address consists of two parts: a network number and a node number. When the Cubix server driver is installed, it must be assigned a unique network number. Each QL 3000 Series node to be supported by the server driver must be assigned a unique node number. The node number is selected by the I.D. Switch (DIP switch SW1) on the QL 3222 board. Valid node numbers range from 2 to 249. It is recommended that the QL 3222 node numbers be assigned consecutively beginning with node number 2 as this will maximize network performance.
The QL 3222 board uses a seven position DIP switch to select its node numbers. Since the QL 3222 contains two nodes, these seven switches determine the seven high order bits of the address for each node. The low order bit for the Port A node is assumed to be 0, while it is assumed to be 1 for the Port B node. A switch is OFF when its handle is away from the board.
