Introduction
The IP•Tube E2 User's Guide provides the information users require to install, congure and operate
the IP•Tube E2product developed and manufactured by Engage Communication Inc. This product
will enable the user to install the function, across an IP network, to move data in a securely packaged
form, to a unit in a remote location. Protocols supported include legacy protocols such as NetBEUI,
IPX, AppleTalk and Decnet. Legacy applications that utilize non-routable protocols are able to access
services across an IP point to point connection.
Security
The IP•Tube E2provides a high level secure communication by only exchanging packets with the
remote network. The Ethernet frames within the IP envelope must be addressed to specic Ethernet
MAC addresses.
Network security is established with Full On Source, Destination Address, UDP Port and IP Packet
ltering. Interconnectivity is selectively controlled at the interface, network device and application lay-
ers.
Management
Management of the IP•Tube E2is accomplished with a Command Line Interface, (CLI), that is ac-
cessed through the console port or a telnet connection. Templates of the most common congurations
provide for an Edit and Paste approach.
Unit Ports and Indicators
Console Port
A console port for "Out of Band" management access to the unit.
LAN Interface
The IP•Tube E2provides two 10/100 BaseT Full/Half Ethernet LAN interfaces with autonegotiation or
congurable speed, and duplex. Management via the LAN ports is enabled when access to the unit
is more convenient remotely. LAN1 typically receives data from a local network and the LAN2 port
moves the encapsulated data to a remote network. LAN protocols IP, TCP and ICMP are supported.
The LNK indicators show connectivity with a green light.

Chapter 2
Installation QuickStart
This QuickStart Chapter is intended for users who understand how they want their IP•Tube E2in-
stalled and congured and only require the mechanics of performing that installation.
Communication with the IP•Tube E2
Console Port
Initial communication with the IP•Tube E2unit is made through the Console port, utilizing the Com-
mand Line interface, (CLI) detailed in Chapter 4: Command Line Interface.
The Console port on the E2 uses an RJ45 jack. It is congured as a DCE port. An RJ45/DB9 adapter
is provided in the shipment which, in addition to providing a physical interface, permits direct connec-
tion to DTE equipment, such as COM connections of a PC.
Once a serial connection between a workstation and the E2console port is established and a carriage
return <CR> is entered, a Login prompt will appear.
The default login is: root.
No password is needed for rst time login.
Telnet
Once an IP address has been assigned and a serial line connected, the user can log into the unit via
the network and continue conguration using telnet. Most telnet programs are compatible with the
IP•Tube E2.
Editing & Pasting Congurations
Users of either CLI have the option of editing a standard IP•Tube E2 conguration in a text editor and
pasting that conguration to the IP•Tube E2. The examples in this chapter are included in a congu-
ration le found on the shipping disk.
Edit the desired conguration listing using a simple text editor. Connect to the E2unit through Telnet
or the Console port, then enter the conguration mode with the command: cong.
Paste the edited text, comments and all, to the IP•Tube E2, then issue the command: save. The unit
will reset and come up with the new conguration.
To save an IP•Tube E2 conguration to a le, issue the command: show conguration all, and copy
the output of the command to a le with your text editor.

IP•Tube E2Cabling
The IP•Tube E2uses standard 10/100BaseT Ethernet cabling to connect to an Ethernet switch, router
or hub. A crossover 10/100BaseT cable can be used for direct connection to a single router, wireless
radio or other Ethernet device.
The cabling used to connect the IP•Tube E2LAN Ports to a switch, router or hub is straight through
Ethernet cabling. Refer to the Appendices for the details of the wiring and pinouts of this cable.
IP•Tube E2 Conguration Parameters
The setup of the IP•Tube E2 involves conguration of the:
IP•Tube E2Security Parameters
Interface Specic Parameters
IP•Tube E2System Parameters
IP•Tube E2Security Parameters
To establish a Full On Source, Destination Address envelopes must be addressed to specic Ethernet
MAC addresses. Interconnectivity is selectively controlled at the interface, network device and ap-
plication layers.
No device on the public network can access, or pass data to LAN1 for delivery to the private network
other then another IP•Tube E2. Thus connectivity via UDP from the public network is limited to the
IP•Tube itself.
Interface Specic Parameters
Console Conguration Parameters
The console port is an RJ45 port and uses an RJ45/DB9 adapter, included with the unit, and can be
connected directly to a desktop or laptop computer for access to the IP•Tube E2. It's conguration is
standard:
9600 baud, 1 stop bit, no parity, 8 bit data, ow control none
LAN Conguration Parameters
The IP•Tube E2 serial interface number 1, "LAN1", is congured for network connectivity. The follow-
ing parameters must match the conguration of the LAN interface to which it is connected.
IP•Tube E2System Parameters
System parameters include the IP•Tube E2Host name, the Ethernet IP address and the default
router.
Host Name
Provide a unique name for the IP•Tube E2.

HOST NAME AptosTubeE2
Ethernet IP address
The IP address is applied on a per-unit basis. For the Ethernet interface, use LAN1 to access the
unit via telnet or both LAN's for connectivity to send data, by UDP, from one location to another. The
IP•Tube E2ETHERNET ADDRESS allows the user to specify the Ethernet MAC address for the
IP•Tube E2IP packet. The IP•Tube E2Ethernet MAC Address needs to match the MAC address of the
destination IP•Tube E2or the Default Router.
Example:
IP ADDRESS aaa.bbb.ccc.ddd/ee
Note: BroadcastRCV should remain ON
Default Router
If the remote IP•Tube E2, whose IP address is congured with IP ADDRESS, resides on a different IP
network from the Local IP•Tube E2, a default router must be specied. The Default Router is typically
the local IP WAN Router.
Example:
IP DEFAULT-ROUTER aaa.bbb.ccc.ddd
With the SHOW CONFIG command you can list the conguration parameters of the system and both
LAN ports. Below is an example of a conguration of the IP•Tube E2 with SNMP Traps turned off and
AUTONEGOTIATION turned on so that "Speed" and "Duplex" will be set automatically.
Example 1:

Chapter 3
Installation of the IP•Tube E2
This chapter provides details on the physical location and connections required for the installation of
Engage IP•Tube E2equipment. Also covered is the initial communication with the IP•Tube E2.
References are made to the IP•Tube E2 Command Line Interface as well as Conguration and Opera-
tion. These topics are covered in detail in later chapters.
The use of Engage IP•Tube E2systems to create a bridge between two Ethernet LANs over an IP
network requires one IP•Tube E2unit at each end.
A standard IP•Tube E2package includes:
IP•Tube E2unit - with installed LAN interface
Console port adapter and cable
Power Converter (110 or 220 VAC input/24 VAC or 24 VDC output)
Documentation Compact Disk with IP•Tube E2 User’s Guide and conguration
examples
Note: power supply not supplied with negative 48 volt models.
Installing the Hardware
Locating the IP•Tube E2
Site consideration is important for proper operation of the IP•Tube E2. The user should install the unit
in an environment providing:
A well-ventilated indoor location
Access within six feet of a power outlet
Two feet additional clearance around the unit to permit easy cable connection
As an option, the IP•Tube E2can be mounted in a standard 19 inch equipment rack, (rack mounts are
available from Engage).
Powering the IP•Tube E2
Engage IP•Tube E2units utilize an external power adapter, available in 110 VAC and 220 VAC ver-
sions, providing DC output.
The appropriate power adapter is provided with each unit. Ensure the power adapter is not connected
to power then plug the DC adapter into the circular rear panel POWER connector.
Connect the power adapter to an appropriate AC power outlet and check the POWER LED on the
front panel of the Engage IP•Tube E2. The POWER LED will be GREEN when the internal diagnostics
have completed.

Console Port
The IP•Tube E2 includes a Console port for initial conguration. It may be used for serial communi-
cation from a local workstation or for remote connection via a modem. The Console port utilizes an
RJ45/DB9 jack.
IP•Tube E2 console port is congured as a DTE (Data Terminal Equipment) port. This allows direct
connection to a DCE (Data Communication Equipment) device such as a modem.
An RJ45 to DB9 adapter is provided with the IP•Tube E2 which performs the null modem operation
permitting direct connection to other DTE equipment, such as the COM1 interface of a PC.
Pinouts for the Console port, as well as Engage supplied adapters, are provided in the Appendices.
Communication to the console port should be set for:
9600 baud, 1 stop bit, no parity, 8 bit xed, ow control none
Once a serial connection between a workstation and the IP•Tube E2console port is established and a
carriage return <CR> is entered, a Login prompt will appear.
The default login is: root.
A password is not needed until it is user set.
Conguring the Engage IP•Tube E2for the LAN
The IP•Tube E2 needs to be congured with a number of parameters for proper operation on the
network, including:
Ethernet IP address and subnet mask
IP data target unit IP address and subnet mask
Default gateway if the IP data target is on another IP network
The conguration procedure depends on the network environment in which the IP•Tube E2is to be
installed.
Note: It is strongly suggested that you congure the IP•Tube E2with its unique network identity be-
fore making any Ethernet or Wide Area connections.
Ethernet Interfaces
Engage IP•Tube E2systems utilize 10/100BaseT Ethernet cable to connect to the Local Area Net-
work. Each system provides a 10/100BaseT interface on the front panel for connection to an Ether-
net switch or hub using a straight-thru Ethernet cable. For direct connection to a PC or other LAN
device, the user should obtain a 10/100BaseT crossover cable.
10/100BaseT Ethernet cabling and crossover pinouts are provided in the Appendices.

Status LEDs
Front panel LEDs provide Power, Console and LAN Interface status.
Power
The Power LED will be green if power has been properly attahed and turned on.
Ethernet
The IP•Tube E2 provides specic information, with RD and TD indicators providing status on packet
transmission and receipt, respectively, on the Ethernet interface.
When receiving, the RD will show a steady or ashing GREEN.
When transmitting, the TD will show a steady or ashing GREEN.
If, after power-on, the IP•Tube E2is unable to acquire a unique network address
on the LAN both TD and RD will be solid green.
Internal DIP Switches
IP•Tube E2systems contain an internal four position DIP Switch which is accessible by removing the
unit rear panel and sliding out the motherboard.
The default setting for all DIP switches is OFF.
Switch 1 - Power cycling the unit with DIP Switch 1 ON forces the IP•Tube E2to return to factory
default settings, (parameters shown in "SHOW CONFIG" are not cleared). Factory settings include
operation from Base Flash and deleting any download upgrades. Ensure Switch 1 is returned to the
OFF position after clearing an upgrade so future upgrades can be performed successfully.
ON also allows a login without a password. This is useful when a password is forgotten. Switch 1 OFF
retains the previously congured password.
Switch 2 - Must be in the OFF position for normal operation.
Switch 3 - This switch must also be set to OFF for normal operation.
Switch 4 - DIP Switch 4 has two functions. When turned ON, it forces the IP•Tube E2into a loop
back mode. This is useful for troubleshooting the Serial connections.

Chapter 4: Command Line Interface11
Engage Communication IP•Tube E2 User's Guide
Chapter 4
Command Line Interface
Command Line access to the IP•Tube E2may be via a serial connection to the Console port or a
Telnet connection to the Ethernet interface.
Telnet, part of the TCP/IP Protocol Suite, provides a general communications facility dening a stan-
dard method of interfacing terminal devices to each other. Any standard Telnet application can be
used to communicate to an Engage IP•Tube E2provided there is IP connectivity between the User
Host and the IP•Tube E2.
For communication through the Console port, standard terminal communication software is used.
Console Communication
Serial communication to the console port should be congured for:
9600 baud, 1 stop bit, no parity, 8 bit xed, ow control none
The console port is an RJ45/DB9 adapter and an appropriate cable and adapter are provided with the
IP•Tube E2for use with standard 9 pin COM ports
The RJ45 console port is congured as a DTE (data terminal equipment) port. This allows direct con-
nection to a DCE (data communication equipment) device such as a modem or connection to other
DTE, such as a terminal.
The RJ45 to DB9 adapter which is provided with the IP•Tube E2serves the null modem function, per-
mitting direct connection to a COM interface on most PCs.
Logging in to the IP•Tube E2
A Telnet session is opened by providing the IP address of the IP•Tube E2. On
opening a Command Line Interface, (CLI) session, via the Console port or Telnet,
the login prompt requires entry of a login ID.
The default login ID: root.
The IP•Tube E2 is shipped with no password set. Passwords are set or modied
with the passwd command, detailed below.
Overview of Commands
The Engage CLI supports shorthand character entry. At most 3 characters are required for the pars-
ing of commands. For example: show conguration can be entered as: sh con. The CLI is not
case sensitive. Description of the commands uses both upper and lower case for syntax denitions
and examples. A full description of the command line interface follows.

The command set can be divided into four categories:
General
Show
Cong
Cong Interface
Online Help
Included in the General commands is the HELP command, providing information on the entire com-
mand set.
Conguration Modes
For the Cong and cong Interface commands, Engage employs a modal approach. The user en-
ters the Cong mode, makes changes, then Saves those changes. On Saving the changes the user
leaves the Cong mode.
The Cong interface mode, within the Cong mode, is used to set parameters for a specied inter-
face. Once in the Conguration mode, the user enters the INTERFACE command. All subsequent
commands apply to the specied interface.
The command prompt indicates the mode of operation:
name# the single “#” indicates standard Telnet mode
name## indicates the IP•Tube E2 is in the Cong mode
name(LAN1)## IP•Tube E2 is in Cong Interface mode for LAN Port 1
To move up one level, from Interface Cong mode to Cong mode, enter the INTERFACE command
with no argument. To change between interfaces when in Interface Cong mode, specify the new
interface. For example:
name(s1)## interface lan1
Note: The LAN1 port is the public interface, commonly receives data and LAN2 is the private port and
generally sends data.
Syntax for Command Parameters
{} == one of the parameters in set is required
[ ] == one of the parameters in set is allowed (optional)
System Level or General Commands
PASSWD
Allows setting or modifying the login password. The IP•Tube E2ships with no password set. On
entering the passwd command, the user is prompted to enter, and conrm, the new password.
