Selecting a Site for the Ethernet Extender Switch
Ethernet Extender Switch should be installed in a location the meets the
following requirements:
The ambient temperature should be between -40°C to 75℃(-40℉to
167℉).
-The relative humidity should be less than 95 percent, non-condensing.
-Surrounding electrical devices should not exceed the electromagnetic field
(RFC) standards.
-Make sure that the Ethernet Extender Switch receives adequate ventilation.
Do not block the ventilation holes on each side of the Ethernet Extender
Switch.
Din Rail Mounting
•Fix the DIN rail attachment plate to the back panel of the Hardened
Managed Ethernet Extender Switch.
•Installation: Place the Hardened Managed Ethernet Extender Switch on
the DIN rail from above using the slot. Push the front of the Hardened
Managed Ethernet Extender Switch toward the mounting surface until
it audibly snaps into place.
•Removal: Pull out the lower edge and then remove the Hardened

Connecting to Power
Redundant DC Terminal Block Power Inputs or 12VDC DC Jack:
12VDC DC Jack
Step 1: Connect the supplied AC to DC power adapter to the receptacle on
the topside of the Ethernet Extender Switch.
Step 2: Connect the power cord to the AC to DC power adapter and attach
the plug into a standard AC outlet with the appropriate AC
voltage.
Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources.
You only need to have one power input connected to run the Ethernet
Extender Switch.
Step 1: Connect the DC power cord to the plug-able terminal block on the
Ethernet Extender Switch, and then plug it into a standard DC
outlet.
Step 2: Disconnect the power cord if you want to shut down the Ethernet
Extender Switch.

Step 2: Prepare cables with corresponding connectors for each port.
Step 3: Consult Cable Specifications Table on previous page for cabling
requirements based on connectors and speed.
Step 4: Connect one end of the cable to the Ethernet Extender Switch and
the other end to a desired device.
Step 5: Once the connections between two ends devices are made
successfully, turn on the power and confirm LED status.
Ethernet Extender Switch Management
This chapter reviews configuration options used by the Ethernet Extender
Switch. It describes the types of management applications, the
communication, and the management protocols that deliver data between
your management device (workstation or personal computer) and the
system. It also contains information about port connection options.
This chapter covers the following topics:
• Management Access Overview
• Key Concepts
• Key Guidelines for Implementation
• Web Management Access
• Administration Console Access
• SNMP Access
• Standards, Protocols, and Related Reading
Management Access Overview
The Ethernet Extender Switch gives you the flexibility to access and
manage the Ethernet Extender Switch using any or all of the following
methods.
The web browser interface and administration console Command Line
Interface (CLI) support are embedded in the Ethernet Extender Switch
software and are available for immediate use.

B&B Electronics – Westlink Commercial Park – Oranmore, Galway, Ireland – Ph [phone] – Fax [phone] – www.bb-europe.com
Administration Console (CLI)
The administration console is an internal, character-oriented, Command
Line Interface (CLI) for performing system administration such as
displaying statistics or changing option settings.
Using this method, you can view the administration console from a
terminal, personal computer, Apple Macintosh, or workstation connected to
the Ethernet Extender Switch’s console port.
There are two ways to use this management method: direct access or
modem access. The following sections describe these methods.
Direct Access
Direct access to the administration console is achieved by directly
connecting a terminal or a PC equipped with a terminal-emulation program
(such as HyperTerminal) to the Ethernet Extender Switch console port.
Terminal-emulation program parameters:
[Default parameters]
115,200bps
8 data bits
No parity
1 stop bit
This management method is often preferred because you can remain
connected and monitor the system during system reboots. Also, certain
error messages are sent to the serial port, regardless of the interface through
which the associated action was initiated. A Macintosh or PC attachment
can use any terminal-emulation program for connecting to the terminal
serial port. A workstation attachment under UNIX can use an emulator such
as TIP.

B&B Electronics – Westlink Commercial Park – Oranmore, Galway, Ireland – Ph [phone] – Fax [phone] – www.bb-europe.com
Modem Access
You can access the Ethernet Extender Switch’s administration console from
a PC or Macintosh using an external modem attached to the console port.
The Ethernet Extender Switch management program provides Console
Port screen, accessible from the Basic Management screen that lets you
configure parameters for modem access.
When you have configured the external modem from the administration
console, the Ethernet Extender Switch transmits characters that you have
entered as output on the modem port. The Ethernet Extender Switch echoes
characters that it receives as input on the modem port to the current
administration console session. The console appears to be directly
connected to the external modem.
Web Management
The Ethernet Extender Switch provides a browser interface that lets you
configure and manage the Ethernet Extender Switch remotely.
After you set up the IP address for the Ethernet Extender Switch, you can
access the Ethernet Extender Switch’s web interface applications directly in
your web browser by entering the IP address of the Ethernet Extender
Switch. You can then use your web browser to list and manage Ethernet
Extender Switch configuration parameters from one central location, just as
if you were directly connected to the Ethernet Extender Switch’s console
port.
SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage
the Ethernet Extender Switch. This management method requires the
SNMP agent on the Ethernet Extender Switch and the SNMP Network
Management Station to use the same community string. This management
method, in fact, uses two community strings: the get community string and
the set community string. If the SNMP Network management station only
knows the set community string, it can read and write to the MIBs.
However, if it only knows the get community string, it can only read MIBs.
The default get and set community strings for the Ethernet Extender
Switch are public.
