FCC Warning Statement
The Cyclades ACS advanced console server has been tested and found to comply with the limits for Class A
digital devices, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the Installation and Service Manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user is
required to correct the problem at his or her own expense.
Notice about FCC Compliance for All Cyclades ACS Advanced Console Server Models
To comply with FCC standards, the Cyclades ACS advanced console server requires the use of a shielded CAT
5 cable for all interface ports. Notice that this cable is not supplied with either of the products and must be pro-
vided by the customer.
Canadian DOC Notice
The Cyclades ACS advanced console server does not exceed the Class A limits for radio noise emissions from
digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.
L’Cyclades ACS advanced console server n’émete pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le règlement sur le brouillage radioélectrique
edicté par le Ministère des Communications du Canada.

CHAPTER
1Introduction
Overview
Each model in the Cyclades®ACS advanced console server family is a 1U appliance serving as a
single access point for accessing and administering servers and other devices, supporting both IPv4
and IPv6 protocols. The following figure shows the front of the console server.
.

2Cyclades ACS Advanced Console Server Installation/Administration/User Guide
NOTE: The number of serial ports and power supplies depends on the model.
Accessing the ACS Console Server and Connected Devices
You can access a console server and the connected servers or devices either locally or remotely
using any of the following methods.
• Web Manager through LAN/WAN IP networks.
• A modem, ISDN, GSM or CDMA optional PCMCIA card.
• Using the Web Manager, you can log in and launch a console session such as Telnet or SSH to
connect to the devices attached to the console server’s serial ports.
• Connecting a server running a terminal emulation program enables an administrator to log into
the console server and either enter commands in the console server shell or use the Command
Line Interface (CLI) tool.
NOTE: Only one root or admin user can have an active CLI or Web Manager session. A second root or admin
user must abort the session or close the other user’s session.
CAUTION: If there are cron jobs running through automated scripts, a root or admin user login can cause the
automated cron jobs to fail.
Web Manager
ACS console server administrators perform most tasks through the Web Manager either locally or
from a remote location. The Web Manager runs in a browser and provides a real-time view of all
equipment connected to the console server.
The administrator can use the Web Manager to configure users and ports. An authorized user can
access connected devices through the Web Manager to troubleshoot, maintain, cycle power and
reboot connected devices.
Access the Web Manager using one of the following ways:
• The IP Network.
• A dial-in or callback connection with one of the following:
Table 1.1: ACS Console Server Connectors
Number Description
1Power connection. This may be single or dual power. Dual power requires two power cords.
2Serial port connectors.
3Ethernet port connectors.
4Console port connectors.

Chapter 1: Introduction 3
• An optional external modem connected to one of the serial ports.
• A modem on an optional PCMCIA modem card.
• An optional CDMA, GSM or ISDN card.
Prerequisites for Using the Web Manager
The following conditions must be met prior to accessing the Web Manager.
• Basic network parameters must be defined on the console server so the Web Manager can be
launched over the network.
• The dynamically-assigned IP address of the console server must be known. This address is
found in one of the following three ways:
• Make an inquiry to the DHCP server on the subnet that the console server resides, using
the MAC address.
• Connect to the console server remotely using Telnet or SSH and use the
ifconfig command.
• Connect directly to the console server and use the ifconfig command through a terminal
emulator application.
• A Web Manager user account must be defined. The admin has an account by default, and can
add regular user accounts to grant access to the connected servers or devices using the
Web Manager.
Types of Users
The ACS console server supports the following user account types:
• The root user who can manage the console server and its connected devices. The root user
performs the initial network configuration. Access privileges are full read/write and
management.
NOTE: It is strongly recommended that you change the default password tslinux before setting up the console
server for secure access to the connected servers or devices.
• Users who are in an Admin group with administrative privileges. The admin user belongs to
this group.
NOTE: It is strongly recommended that you change the default password cyclades for the admin user.
• Regular users who can access the connected devices through the serial ports they are
authorized for. Regular users have limited access to the Web Manager features.
Security
The Cyclades ACS advanced console server includes a set of security profiles that consists of
predefined parameters to control access to the console server and its serial ports. This feature

4Cyclades ACS Advanced Console Server Installation/Administration/User Guide
provides more control over the services that are active at any one time. As an additional security
measure, all serial ports are disabled by default, allowing the administrator to enable and assign
individual ports to users.
NOTE: The Default security profile parameters are the same as the Moderate profile.
Authentication
The ACS console server supports a number of authentication methods to assist the administrator
with user management. Authentication can be performed locally or with a remote server, such as
RADIUS, TACACS+, LDAP or Kerberos. An authentication security fallback mechanism is also
employed should the negotiation process with the authentication server fail. In such situations, the
console server follows an alternate defined rule when the authentication server cannot authenticate
the user.
The following table lists the supported authentication methods.
Table 1.2: Authentication Methods Supported
Authentication Type Definition
None No authentication.
DSView Authentication is performed with a DSView®3 server.
DSView/Local DSView management software authentication is tried first, then Local.
DSViewDownLocal Local authentication is performed only if the DSView 3 server is down.
Kerberos Authentication is performed using a Kerberos server.
Kerberos/Local Kerberos authentication is tried first, switching to Local if unsuccessful.
KerberosDownLocal Local authentication is performed only when the Kerberos server is down.
LDAP Authentication is performed against an LDAP database using an LDAP server.
LDAP/Local LDAP authentication is tried first, switching to Local if unsuccessful.
LDAPDownLocal Local authentication is performed only when the LDAP server is down.
LDAPDownLocal/Radius Local authentication is performed only when the LDAP server is down, switching
to Radius if unsuccessful.
Local Authentication is performed locally. For example using the /etc/passwd file.
Local/Radius Authentication is performed locally first, switching to Radius if unsuccessful.
Local/TACACS+ Authentication is performed locally first, switching to TACACS+ if unsuccessful.
Local/NIS Authentication is performed locally first, switching to NIS if unsuccessful.
