1.0 System Description
The ConsoleServer 800 provides a compact solution for remote and local
management of up to eight devices with RS-232C compatible serial consoles.
As many as ten users may simultaneously access different consoles through the
ConsoleServer.
The ConsoleServer 800 is factory-configured with eight device ports, one local
terminal port, one network connection, and can have an optional modem card.
The unit can be configured at time of manufacture for either universal AC
operation or –48 VDC operation. Both power supply configurations feature
redundant power supplies.
All system parameters are stored in non-volatile data flash memory. User
profiles, port configurations, and other system parameters are saved even when
the unit is not powered. A maximum of 50 user profiles may be stored per
system.
The system software held in flash memory can be updated while the unit is
installed. The ConsoleServer will not send breaks to the attached servers during
the flash update process. Updates are sent to the unit using either a serial
connection to the terminal port (using the Xmodem or Kermit file transfer
protocols), or by a tftp download through the network port. See Appendix B for
further details and the flash update procedure.
1.1 Features
•Connect up to eight RS-232C serial consoles
•No unintentional break will ever be sent to attached servers
•64KB of buffered data storage per device port
•Local access through terminal port
•Remote access through network and optional modem
•1 RU (1.75 inches) high
•Redundant power supplies

2.0 System Overview
2.1 Typical Use
The ConsoleServer 800 is typically used to manage up to eight rack-mounted
servers or switches where rack space is at a premium. Each attached device
must have an RS-232C compatible serial console port.
2.2 System Components
All system components are enclosed in a rack-mountable metal chassis. Each
chassis is factory-configured with eight device ports, one terminal port, and one
network port. An optional modem card is available. Power supplies are factory-
installed, and may be either for universal AC operation, or for –48 VDC
operation. The ConsoleServer 800 front panel features an LCD display and two
push buttons for access to system information.
2.3 Access Control
Access to attached servers is controlled by assigning access rights to system
user profiles. Each user profile is assigned an ID, a password, I/O rights. Users
must have a user profile to access any of the attached devices.
2.4 Connection Formats
2.4.1 Serial
All devices attached to both the device ports and the terminal port must support
the RS-232C standard. The serial communications parameters may be set by
the system administrator to match the attached equipment.
Be sure to use Lightwave RJ45 to DB25 or DB9 adapters to assure the proper
transmission of serial signals. Appendix A contains the pinouts for the RJ45
serial connectors and adapters.
2.4.2 Network
The ConsoleServer 800 network interface connects to a TCP/IP network using
standard RJ45-terminated Cat 5 cables. The network must use IPv4. The point
of connection to the network must operate at 10 Mbits half duplex, with no auto-
negotiation.

3
The network parameters must be configured by the system administrator through
the terminal port before the ConsoleServer may be accessed over the network.
2.4.3 Modem
The optional modem card connects to a POTS line using standard RJ11 modular
telephone cable. The analog modem on the card connects at speeds up to
38,400 baud.
2.5 Device Port Buffer
Each device port stores 64 KB (approximately 100 screens) of I/O data in a FIFO
buffer. This data is viewed while the user is not directly interacting with the
attached device.

Repeat the above steps if a redundant power input is to be attached.
3.4 Connecting a Terminal
The terminal port is used for local access to the ConsoleServer 800 and the
attached devices. The system administrator must also use the terminal port to
set up the configuration for the network port before the ConsoleServer 800 can
be accessed from the network. A dumb terminal or computer may be attached to
the serial port if the serial port uses RS-232-C protocol and vt100 emulation is
supported.
Inserting a cable in the terminal port
The default communication parameters for the terminal port are: 9600 baud, 8
data bits, 1 stop bit, no parity, Xon/Xoff flow control, and a port type of
DCE.
Adapters from Lightwave Communications must be used to connect the terminal
port to the serial port on a terminal. Otherwise, the serial pin signals may not
match and there will be no communication between the two units. See Appendix
A for adapter and port pinouts.

8
Installation:
Materials:
•ConsoleServer 800 terminal port
•terminal or computer with RS-232 serial port
•RJ45-terminated Cat 5 cable (standard LAN cable)
•Lightwave adapter for terminal serial port
1. Attach the Lightwave adapter to the terminal or computer serial port.
2. Connect the Cat 5 cable to the adapter. Connect the other end to the
ConsoleServer 800 terminal port.
3. Turn on the terminal or start the computer’s communication program.

match those of the terminal port (see above).
3.5 Connecting to the Device Port
Any device that has a serial console port (such as a server or a switch) may be
connected to the ConsoleServer for consolidated remote administration. The
console port must support the RS-232-C serial protocol. Additionally, many
servers must either have the serial port enabled as a console, or must have the
keyboard and mouse detached. Consult the server hardware and/or software
documentation for more information.

9
The default communication parameters for the device port are: 9600 baud, 8
data bits, 1 stop bit, no parity, Xon/Xoff flow control, and a port type of
DCE. Most equipment that uses serial console ports uses values complimentary
to the above settings, so it is not usually necessary to change the device port
parameters.
Adapters from Lightwave Communications must be used to connect the device
port to a serial console port. Otherwise, the serial pin signals may not match and
there will be no communication between the two units. See Appendix A for
adapter and port pinouts.
Installation:
Materials:
•ConsoleServer 800 device port
•device with RS-232-C serial console port
•RJ45-terminated Cat 5 cable (standard LAN cable)

2. Connect the Cat 5 cable to the adapter. Connect the other end to the
ConsoleServer 800 device port.
3. Check that the device port and serial console port communications
parameters match, and synchronize them if they do not match. See
sections 4.3 and 4.6.3 for more information regarding the device port
parameters.
3.6 Connecting the Network Port
The ConsoleServer 800’s network port allows remote access to the attached
devices and the system administrative functions. Up to eight remote users may
telnet to the ConsoleServer, along with one remote administrator.
NOTE:
The point of connection for the ConsoleServer (e.g., a network switch)
must run at 10 Mbits, half-duplex with no auto-negotiation. It is imperative
that there is no auto-negotiation of the connection speed, as this will
prevent the establishment of a functioning network connection.
It is also recommended that the network run pure TCP/IP, and not a combination
of protocols.

10
The network parameters for the network port must first be set up through the
serial terminal port before the ConsoleServer 800 may be reached remotely.
See section 4.4 for more information.
Installation:
Materials:
•ConsoleServer 800 network port
•network point-of-connection
•RJ45-terminated Cat 5 cable (standard LAN cable)
1. Configure the ConsoleServer network parameters to the desired values as
outlined in section 4.4.
2. Configure the network point-of-connection. It must be manually set to 10
Mbits, half-duplex, with no auto-negotiation.
3. Connect the ConsoleServer network port to the network using a standard
LAN cable.
4. Check the status lights at each end of the connection. Both should
indicate a good link. Try reaching the IP address assigned to the
ConsoleServer by using PING or TELNET. If there is a problem, check the
network configuration.
3.7 Connecting the Modem Port
An optional modem port is available for the ConsoleServer 800. The modem
may be installed at the factory or can be ordered separately for later installation.
See section 3.8 for the procedure to install a modem card in a previously
purchased system.

4.0 ConsoleServer 800 Administration
The following section outlines the administration functions and commands. The
administration functions and commands are designed to enable the administrator
to configure the ConsoleServer 800 to fit the needs of the system application.
User IDs, devices, terminals and access rights may be configured using the
administration commands. As new features are added to the product, the
administration user will also be used to install new flash memory software
updates (see section 4.10, Updating the ConsoleServer 800 Software, and
Appendix B).
The administrator may not access device ports; only users may access
device ports (see section 5.0, User Access and Interface).
Screen shots of interactive terminal sessions are shown in outlined boxes, while
in-text command words and system responses are in a different font to
differentiate them from normal text. All system commands require the <ENTER>
key to respond, but are not case-sensitive unless otherwise specified.
Many commands may be abbreviated to one extent or another, but some may
not be abbreviated at all. For example, the command VERSION may be
abbreviated to VER, but LCIUPDATE may not be abbreviated. See Appendix E
for more information regarding abbreviations.
NOTE:
<ESC> <ESC> or <CTRL>+C will cancel an operation and return to the
administrator prompt. Pressing <CTRL>+R at the LCI800> or sys admin>
prompt will discard the characters on the current command line, and retype the
last command used; <ENTER> must still be pressed to execute the command.
Pressing <CTRL>+U at either prompt erases the current command line back to
the prompt.
4.1 Power-up Sequence and Basic Use of the Administrator Functions
When the ConsoleServer 800 is first installed and powered up, it must be
configured through the serial terminal port. Connect the terminal port to a
terminal device or computer using a terminal emulation program (refer to section
3.4 for instructions on connecting to the terminal port). After the network
interface has been configured (see section 4.4), the administration login may also
be reached via telnet. All the functions available from a local serial connection
(with the exception of BACKUP and RESTORE) are also available through telnet by
connecting to port 5000 of a ConsoleServer’s network IP address.
Administration access via modem is not supported at this time.
