1101 and 1102 Secure Device Servers

2. Overview

2.1 Introduction

This User’s Manual walks you through installing and configuring your Black Box Secure Device Servers (LES1101A or LES1102A). Each of these products is referred to generically in this manual as a “console server.”

Once configured, you will be able to use your console server to securely monitor access and control the computers, networking devices, telecommunications equipment, power supplies, and operating environments in your data room or communications centers. This manual guides you in managing this infrastructure locally (across your operations or management LAN or through the local serial console port), and remotely (across the Internet or private network).

2.2 Manual Organization

This manual contains the following chapters:

2.3 Types of Users

The console server supports two classes of users:

First, there are the administrative users who will be authorized to configure and control the console server; and to access and control all the connected devices. These administrative users will be set up as members of the admin user group and any user in this class is referred to generically in this manual as theAdministrator. AnAdministrator can access and control theconsole server using theconfig utility, the Linux command line, or thebrowser-basedManagement Console. By default, theAdministrator has access to all services and ports to control all the serial connected devices and network connected devices (hosts).

The second class of users are those who have been set up by the Administrator with specific limits of their access and control authority. These users are set up as members of the users user group (or some other user groups theAdministrator may have added). They are only authorized to perform specified controls on specific connected devices and are referred to asUsers. TheseUsers (when authorized) can access serial or network connected
