Product Overview
The MiniArrayIII Model MA6 is a ruggedized, highly expandable 19" rack mount device that
includes a built-in hard drive, 3.5" floppy drive, and also contains a slot for a CD-ROM drive.
The heart of the MA6 is MultiTech's high-powered Pentium-based single-board computer
(SBC) with up to 200 MHz of processing power. The MA6 has five expansion slots, four that
meet the ISA standard, and one that accommodates either ISA or PCI devices. A user
configurable card cage allows for up to 32 enhanced V.34 (33.6 bps) internal modems or up
to 32 high speed serial ports.
The MiniArrayIII is shipped with RASExpress remote access server and MultiManager
software installed. Two MiniArrayIII Model 6 versions are shipped; one is equipped with
RASExpress software and internal modems, and the other has RASExpress software and
serial ports for external communications devices. Both have a default configuration that
allows them to boot up as remote-access servers (RAS).
RASExpress and Auxiliary Software
The MiniArrayIII's factory-installed RASExpress software is an advanced remote-access software
package that enables network managers to configure and manage remote servers via web browsers,
through Telnet over an IP network, and via a GUI manager over both IP and IPX networks. Through a
special software package bundled with the MiniArrayIII, RASExpress can also be interfaced to
standard RADIUS authentication functionality (which resides on a separate P ).
RADIUS authentication software (Remote Authentication Dial-In User Service) handles
authentication and profile information about network users and ensures security against unauthorized
server access. Built-in R log protocol support permits remote log-in to all hosts on the network.
RASExpress can facilitate remote software upgrades via standard TFTP protocol.
The MiniArrayIIIs workstation re-director programs (WINM SI and M SIWSN) control modem port
assignments on the network.
