CHAPTER 1 Introducing the
RAS 2000 PowerRack
The RAS 2000 PowerRack (RAS 2000) is the newest member of Computone’s
IntelliServer family of high performance network access servers. It provides
remote access with up to 64 high-speedasynchronous serial ports and provides lo-
cal access through standard Ethernet network connections.
The RAS 2000 has many features that are especially valuable to larger
remote-access providers. These include:
• Up to 64 PPP/SLIP connections
• 19” rack mount or table-top installation
• Serial Line speeds up to 921,600 baud
This manual is divided into three parts:
• Chapter 1 gives an overview of the RAS 2000 PowerRack and its
features.
• Chapter 2 explains how to unpack and install the RAS 2000 PowerRack
hardware.
• Chapter 3 shows how to connect modems, terminals, printers, and other
serial devices to the RAS 2000 PowerRack.

Notes:
1) When getting upgrades from our FTP site, examinethe file names and descriptions to
ensure you download the correct software.
2) You cannot save a configuration to a host and then restore it to a different model of
IntelliServer. If you attempt to do this, the IntelliServer will report an error, "Bad Magic
Number" which means that the file you are attempting to restore the configuration from
is not in the proper format.

Welcome to the RAS 2000 PowerRack
The RAS 2000 PowerRack is an expandable asynchronous communications serv-
er that includes a long list of standard features and extensive protocol support. It
combines the functionality of a high-performance terminal server with the extend-
ed capabilities of a communications server.
The RAS 2000 extends your corporate network to remote users worldwide. Net-
work users can now work anywhere and gain access for your network, remote cli-
ent access, multi-user host access, and remote office access. In addition, it
provides high performance, scalability from 16 to 64 serial lines, full protocoland
feature support (see Table 1-1), and an easy-to-use design.
The RAS 2000 PowerRack provides:
•Transparent remote access to Ethernet LANs
•Easy access to INTERNET services
•TCP/IP traffic routing using the industry standard PPP protocol
•PC clients with dial-in access into the network for shell, telnet, or rlogin
access
•Industry standard TCP/IP client software such as available in Windows95,
Windows NT Workstation, UNIX, Windows 3.x and Macintosh with third
party PPP client software
•Easy-to-use dial-up router functionality for serial connection to a home
office, INTERNET services, or dial-in/dial-out modem accesses for remote or
branch offices

RAS 2000: Highest Performance and Rack-Mount Convenience
The new PowerRack provides high performance with the convenience of an en-
closure that can be rack mounted or set on a table. Serial port bit rates up to 921.6
Kbps on all serial channels meet and exceed the most demanding throughput
requirements using V.34 modems and/or ISDN links.
The RAS 2000 PowerRack can be connected directly to a TCP/IP Ethernet LAN
or can be booted independently and operated as a stand-alone unit. It requires no
special operating system device drivers which simplifies upgrades and TCP/IP
host cross-platform connectivity.
Flexibility and Speed
The RAS 2000 is a compact, high-performance communications server complete
with a 32-bit MIPS-R3000 compatible CPU, 8 MB of RAM, resident multi-task-
ing operating system, and menu-driven interface. It supports all standard RS232
serial devices: terminals, PCs, printers, modems, bar code scanners, and POS
equipment.
Each connected serial device can communicate at baud rates of up to 921.6 Kbps
full-duplex. TheRAS 2000 also includes a utility that allows a UNIXnetworkhost
to access ports as if they were local tty devices. Modem ports can be used for both
dial-in and dial-out access, thus ending the requirementfor dedicatedinbound and
outbound modems. Sharedresources such as printers andmodemscan beassigned
to shared "hunt groups."
RADIUS and RIP Support Features
The RAS 2000's extensive protocol support includes rlogin, telnet, telnetd,
reverse telnet, RADIUS, RIP, plus a special IP Filtering feature that allows you to
define and regulate the flow of selected IP packets.
The standard feature list includes full PPP, SLIP, and CSLIP support, permitting
IP devices to be connected over an RS232 serial port at up to 921.6Kbps. This
offers an ideal solution for sites that wish to implement cost-effective remote
access, INTERNET access, and LAN-to-LAN interconnections.

Easy To Install
TheRAS 2000 PowerRack is equippedwith16 serial portsand isexpandable with
threeadditional sixteen-portserial cards (REX-16RJ-232). These cards come with
integralfront panelsandprovidea total of64physical ports,96 login sessions, and
up to 64 PPP/SLIP connections. The serial cardsslide into chassis card guides and
are secured with frontpanel screw locks.All connections, except for the power ca-
ble, are conveniently located and visible from the front.
RAS 2000 units and expansion modules are easy to install and can be mounted on
a desk, floor, or rack. Surge/spike protection is standard on all transmit (TxD) and
receive (RxD) and data set signals.
