T
he Rackmount 10/100 Serial
Terminal Servers are an
excellent way to link PCs,
terminals, printers, modems, and
other serial devices to Ethernet
networks. They support
simultaneous connections to
each of their ports as well as one
10BASE-T link.
These terminal servers, by
connecting each device directly
to the network, conserve host
ports and enable each terminal to
access multiple hosts. Also,
terminal cabling on the network
is greatly simplified. For conveni-
ence, the 10BASE-T link can be
made through the RJ- 5 port or
the BNC port.
Each port supports up to eight
sessions—LAT, Rlogin, and
Telnet™. This feature is
augmented with a load-balancing
mechanism through which the
unit chooses the least busy
connection for each session. The

result is better overall response
time and balanced terminal
usage.
Configuration is simplified
through EZWebCon, a software
package included with the
terminal server. You can also
enter command lines from a serial
port connection, or you can log in
via NetWare®, LAT, or NCP/TSM.
You can also download standard
configuration files from TCP/IP,
LAT, or NetWare hosts during
startup.
Once configuration is
complete, operating the units is
easy. In local mode, each
supports command line editing,
command line recall, and
command completion. The
operating code is downloaded
automatically at start up, and the
Flash-ROM units provide
permanent storage for operating
software. For upgrades, simply
download the newest version.
If you run into trouble, an
extensive context-sensitive help
menu is available. For general
help, simply type “HELP.” For help
on a particular command, type
“HELP command.” You can also
place a question mark at the end
of a full or partial command line
for help at that specific point.
The units support industry-
standard protocols, including:
• AppleTalk®: Enables
Macintosh®computers on
the network to access
attached devices.
• LAN Manager: Enables
attached devices to access
network printers. Supports
OS/2®and Windows NT®.
• Local Area Transport:
Supports almost all digital
systems as well as remote
logins and host-initiated
print spooling.

The terminal servers boast
strong security features. They use
group codes, which limit users’
access to manager-chosen
services or devices. At the port
level, users are logged out
automatically as soon as a port is
disconnected or a device turned
off. Other standard features
include user-defined password
protection (by port), IP security
tables, dialback capabilities, and a
menu mode that enables
managers to impose command
restrictions based on a user’s
security level.
Remote configuration is
possible through a variety of
methods: digital login, Telnet, and
the included EZCon configuration
software, which supports logins
through TCP/IP, LAT, NetWare,
Windows®, UNIX, and AppleTalk.
The 10/100 Serial Terminal
Servers also support SNMP.
NOTE: No enterprise-specific
MIBs are supplied with the unit.
