Chapter 1 Introduction
INTRODUCTION
This Manual
This User’s Manual walks you through installing and configuring your Black Box Console Server
(LES1108A, LES1116A, LES1148A) or Advanced Console Server (LES1208A, LES1216A, LES1248A). 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, private network, or via dial up).
Manual Organization
This manual contains the following chapters:
1. Introduction An overview of the features of console server and information on this
manual.
2. Installation Physical installation of the console server and how to interconnect
controlled devices.
3. System Configuration Describes the initial installation and configuration using the
Management Console. Covers configuration of the console server on the
network and the services that will be supported.
4. Serial & Network Covers configuring serial ports and connected network hosts, and
setting up Users and Groups.
5. Failover and OoB dial-in Describes setting up the high availability access features of the console
server.
6. Secure Tunneling (SDT) Covers secure remote access using SSH and configuring for RDP, VNC,
HTTP, HTTPS, etc. access to network and serially connected devices.
7. Alerts and Logging Explains how to set up local and remote event/data logs and how to
trigger SNMP and email alerts.
8. Power & Environment Describes how to manage USB, serial, and network attached power
strips and UPS supplies including Network UPS Tool (NUT) operation,
IPMI power control, and EMD environmental sensor configuration.
9. Authentication Access to the console server requires usernames and passwords that are
locally or externally authenticated.
10. Nagios Integration Describes how to set Nagios central management with SDT extensions
and configure the console server as a distributed Nagios server.
11. System Management Covers access to and configuration of services that will run on the
console server.

12. Status Reports View a dashboard summary and detailed status and logs of serial and
network connected devices (ports, hosts, power, and environment)
13. Management Includes port controls that Users can access.
14 Basic Configuration Command line installation and configuration using the config command.
15. Advanced Config More advanced command line configuration activities where you will
need to use Linux commands.
The latest update of this manual can be found online at www.Black Box.com/download.html
Types of users
The console server supports two classes of users:
I. 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 the Administrator. An Administrator can access and control the console server using the
config utility, the Linux command line, or the browser-based Management Console. By default, the
Administrator has access to all services and ports to control all the serial connected devices and
network connected devices (hosts).
II. 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 the Administrator may have added). They are only authorized to perform
specified controls on specific connected devices and are referred to as Users. These Users (when
authorized) can access serial or network connected devices; and control these devices using the
specified services (for example, Telnet, HHTPS, RDP, IPMI, Serial over LAN, Power Control). An
authorized User also has a limited view of the Management Console and can only access authorized
configured devices and review port logs.
In this manual, when the term user (lower case) is used, it refers to both the above classes of users. This
document also uses the term remote users to describe users who are not on the same LAN segment as
the console server. These remote users may be Users, who are on the road connecting to managed
devices over the public Internet, or it may be an Administrator in another office connecting to the
console server itself over the enterprise VPN, or the remote user may be in the same room or the same
office but connected on a separate VLAN than the console server.
Management Console
The Management Console provides a view of the console server and all the connected devices.
Administrators can use any browser to log into the Management Console either locally or from a remote
location. They can then use Management Console to manage the console server, the users, the serial
ports and serially connected devices, network connected hosts, and connected power devices; and to
view associated logs and configure alerts.

_____________________________________________________________________
724-746-5500 | blackbox.com Page 13
A User can also use the Management Console, but has limited menu access to control select devices,
review their logs and access them using the built-in java terminal or control power to them.
The console server runs an embedded Linux operating system, and experienced Linux® and UNIX® users
may prefer to configure it at the command line. To get command line access, connect through a terminal
emulator or communications program to the console serial port; connect via ssh or telnet through the
LAN; or connect through an SSH tunneling to the console server.

Chapter 3 Initial System Configuration
SYSTEM CONFIGURATION
Introduction
This chapter provides step-by-step instructions for the console server’s initial configuration, and for
connecting it to the Management or Operational LAN. The Administrator must:
Activate the Management Console.
Change the Administrator password.
Set the IP address console server’s principal LAN port.
Select the network services that will be supported.
This chapter also discusses the communications software tools that the Administrator may use to access
the console server.
3.1 Management console connection
Your console server is configured with a default IP Address 192.168.0.1 Subnet Mask 255.255.255.0
Directly connect a PC or workstation to the console server.
Note For initial configuration we recommend that you connect the console server directly to a single PC
or workstation. However, if you choose to connect your LAN before completing the initial setup
steps, it is important that:
you make sure that there are no other devices on the LAN with an address of 192.168.0.1
the console server and the PC/workstation are on the same LAN segment, with no interposed
router appliances.
3.1.1 Connected PC/workstation set up
To configure the console server with a browser, the connected PC/workstation should have an IP
address in the same range as the console server (e.g. 192.168.0.100):
To configure the IP Address of your Linux or Unix PC/workstation simply run ifconfig
For Windows PCs (Win9x/Me/2000/XP/ Vista/ NT):
Click Start -> (Settings ->) Control Panel and double click Network Connections (for
95/98/Me, double click Network).
Right click on Local Area Connection and select Properties.
Select Internet Protocol (TCP/IP) and click Properties.
Select Use the following IP address and enter the following details:
oIP address: 192.168.0.100
