How To Use This Manual

This manual assumes that the reader understands networking basics and is familiar with the terms and

concepts used in Local and Wide Area Networking. The PortServer CM is a Linux-based secure console

access server, which gives it great flexibility. It runs an embedded version of the Linux operating system and

UNIX and Linux users will find the configuration process very familiar. On the other hand, users not

familiar with UNIX will have a steeper learning curve, but it is not necessary to be a UNIX expert.

Configuration of the equipment is done by editing a few plain-text files (commented sample files for the

principal profiles are provided in appendix C), and then updating the versions of the files in the PortServer

CM. The files can be edited in the PortServer CM using the vi editor provided, or in another computer with

the environment and text editor of your choice. UNIX user or not, we strongly recommend that you follow

the steps in this installation manual before jumping in. This manual should be read in the order written, with

exceptions given in the text.

Use the following safety guidelines to protect yourself and your PortServer CM.

CAUTION: Do not operate your PortServer CM with the cover removed.

•

In order to avoid shorting out your PortServer CM when disconnecting the network cable, first unplug

the cable from the equipment and then from the network jack. When reconnecting a network cable to the

equipment, first plug the cable into the network jack, and then into the equipment.

To help prevent electric shock, plug the PortServer CM into properly grounded power source. The cable

is equipped with 3-prong plug to help ensure proper grounding. Do not use adapter plugs or remove the

grounding prong from the cable. If you have to use an extension cable, use a 3-wire cable with properly

grounded plugs.

•

To help protect the PortServer CM from transients in electrical power, use a surge suppressor, line condi-

tioner, or uninterruptible power supply.
