QL 3002
Chapter 1 - Introduction
Introduction
Hardware Overview
The QL 3002 features two remote communications processor-based products which function as diskless workstations on a Novell network. The QL 3002 must be installed in either a NetWare file server or an external bridge or router. NetWare versions 2.15C, 2.2, and 3.11 are currently supported.
Although the QL 3002 can function in a variety of application environments, it is typically used to host remote sessions. A modem is connected to the standard serial COM port on each QL 3002 processor. Two simultaneous remote users can then dial into the network via the QL 3002. Figure 1-1
The QL 3002 contains two computers on a single AT-style plug-in board. The standard QL 3002 is equipped with two 80386SX processors. The QL 3002CX uses the higher performance Cyrix Cx486SLC processors. Both models of the QL 3002 are ISA-bus compatible.
The QL 3002 and the QL 3002CX provide most of the functionality of standard AT-class computers. Each processor includes VGA support, two serial ports, one parallel port, and up to 16MB of RAM. The standard QL 3002 is compatible with the 80387SX math coprocessor, and the QL 3002CX is compatible with the Cyrix Cx87SLC. Figure 1-2
Since the QL 3002 products are installed as remote communication host processors, the ability to directly connect a monitor and keyboard to the processors is not usually required. However, to provide for times when the network administrator wishes to connect a monitor and keyboard to a QL 3002 workstation, Cubix supplies an adapter for this purpose (refer to Chapter 3). In addition, the QLVision software utility allows the screen and keyboard I/O to be redirected to another workstation on the LAN (refer to the QL 3000 Series Guide to Operations).
The QL 3002 boards function as diskless workstations. All of the files necessary to boot and run a QL 3002 workstation reside on a NetWare file server. Therefore, there is no disk controller interface on the boards.
Both the standard QL 3002 and the QL 3002CX have been uniquely engineered and designed for remote communication integration on a Novell NetWare network. Cost effectiveness has been achieved through the elimination of standard AT-class computer hardware which is not required in a remote communication environment, while AT compatibility has been maintained. Expanded support for the Cyrix Cx486SLC provides additional performance at a low cost for processor-intensive applications.
In addition to the optional math co-processor support, both the standard QL 3002 and the QL 3002CX are compatible with the Cubix Line Busy Module. The purpose of the Line Busy Module is to make the telephone line appear busy when the QL processor or modem is not ready to answer an incoming telephone call.
