Chapter 1
Introduction
Overview
Net Optics 2xN 10/100/1000 Span Port iMatrix Switches enhance LAN vis-
ibility by providing access across multiple 10/100/1000 Span ports for one or
two distributed analyzers. The physical layer connections through the iMatrix
Switch eliminate the need to reconnect and recongure analyzers for each new
monitoring task. This exibility instantly improves ease of use and return on
investment.
The 2xN 10/100/1000 Span iMatrix Switch supports simultaneous passive
monitoring of any two Span ports connected to the iMatrix Switch, each with
a separate distributed analyzer.
Scalable Deployment
Double or triple Span port coverage by daisy chaining iMatrix Switches. The
Daisy Chain option allows a single distributed device to manage up to three
iMatrix Switches and 96 Span ports. Models with 2x8, 2x16, and 2x32 Span
port densities are available.
Remote Control
The iMatrix Switch Web Manager and iMatrix Switch System Manager allow
you to remotely set IP parameters and change which link is monitored with a
click of your mouse. The Web Manager is browser-based interface accessible
from any PC with a browser and access to the iMatrix Switch’s IP address.
The iMatrix Switch System Manager is SNMP-based.
Reliability
For extra uptime protection, Net Optics iMatrix Switches offer redundant
power connections. Should the primary power source fail, the iMatrix Switch
automatically switches to the backup power source. Power LEDs on the front
of the iMatrix Switch indicate the current power source.

steady green. If there is current activity on this link, the LED ashes.
10/100/1000 Indicator: If the Port is set to 10 Mbps, the LED will illuminate
orange. If the Port is set to 100 Mbps, the LED will illuminate yellow. If the
Port is set to 1000 Mbps, the LED will illuminate green.
Main and Redundant Power: If the Tap is deployed with both power sup-
plies, both LEDs illuminate when the Tap is connected to power. An off power
LED indicates that the corresponding power supply is not functioning or not
connected.

Installing the iMatrix Switch
Overview
The procedure for installing the iMatrix Switch follows these basic steps:
Plan the installation
Congure IP parameters
Mount the iMatrix Switch
Connect the Management Port
Connect to the Span ports
Connect to the monitoring devices
Apply power to the iMatrix Switch
Check the installation
Installation Planning
There are two methods for connecting your iMatrix Switch to monitoring
devices. To determine which method best suits your application, please take a
moment to review the features listed below.
Single iMatrix Switch Mode
• A single iMatrix Switch controlled from the CLI or remote interfaces.
Daisy Chaining Mode
Allows up to three iMatrix Switches to be controlled through a iMatrix
Switch designated as the Controller.
Remote Access
The remote access feature requires that you assign an IP address to the
iMatrix Switch. If you are daisy chaining iMatrix Switches, you only need an
IP address for the Controller iMatrix Switch. You may also wish to assign a
netmask.
If you plan to remotely access and control the iMatrix Switch over WAN, you
can also set a gateway and IP address where you plan to use System Manager
or other SNMP management tool.

2xN 10/100/1000 Span Port iMatrix Switch
Conguring the iMatrix Switch
The iMatrix Switch is congured with default values that allow you to install
the iMatrix Switch and then modify parameters from Web Manager or SNMP
Manager.
The defaults values are:
IP Address: 10.60.0.123
Netmask: 255.255.0.0
Monitor Port 1: Gigabit
Monitor Port 2: Gigabit
CLI username: netoptics
CLI password: netoptics
You can set all parameters, check status, and view statistics from the Com-
mand Line Interface. You can change most settings later from one of the
remote interfaces.
Using the Command Line Interface (CLI)
All conguration and control options are accessible from the iMatrix Switch's
Command Line Interface. You must set a new username and password, IP
address for the iMatrix Switch, and the port speeds. Other parameters are
optional and dependent on your installation.
For security reasons, some parameters can only be set with the CLI.
Use these commands to:
Set CLI username and password
Enable or disable the remote interfaces
Turn character echo to the terminal emulation software on or off
If you wish to disable the Management Port and remote interfaces, you can do
so from the CLI using the Display command.
To access the iMatrix Switch CLI:
1. Make sure power to the iMatrix Switch is off.
2. Connect a PC with terminal emulation software, such as HyperTerminal, to
the iMatrix Switch Control Port 2 using the RS232 cable supplied with the
iMatrix Switch.

Connecting to Switch Span Ports
1. Connect Span Port 1 of the iMatrix Switch to the appropriate Span port on
your switch using a CAT5e straight-through cable.
2. Repeat Step 1 for each additional network switch Span port you wish to
monitor.
Figure 9: Connecting Span Ports
Connecting to the Monitoring Device
You need to connect the iMatrix Switch to input ports (NICs) of the monitor
device and connect the Control Port to a COM port on the monitoring device
or the computer from which you are accessing the CLI.
1. Verify that the DIP switch positions (located on the rear of the unit) are set
as shown in Figure 10 below.

Daisy Chaining iMatrix Switches
You have the option of connecting as many as three switches together for
control by a single monitoring device or computer. It does not matter if you
are connecting both monitoring ports to one device or two separate devices.
In a daisy-chain conguration, one iMatrix Switch serves as the Controller
to one or two Client iMatrix Switches. The Controller/Client relationship is
set with the DIP switches on the rear of the iMatrix Switch. iMatrix Switches
are set to function as a Controller by default. Network trafc is passed from
the Clients to the Controller and control is sent through the Controller to the
Clients.
The basic steps to daisy chaining iMatrix Switches are:
1. Connect the Controller iMatrix Switch as described in the previous sec-
tions.
2. Connect the Controller and Client Control Ports.
3. Connect the Controller and Client Monitor Ports.
4. Connect the additional Span Ports.
To daisy chain iMatrix Switches:
1. Congure and install the Controller iMatrix Switch as described in the
preceeding sections.
2. Choose the iMatrix Switch you will use as Client 1 and set the DIP switch
positions (located on rear of unit) as shown in Figure 13. If you are install-
ing a third switch, set the DIP switch as shown in Figure 13 for Client 2.
3. Connect a CAT5e cable between the Daisy Chain Ports of iMatrix Switch
1 and the Monitor Ports of iMatrix Switch 2. If connecting a third iMatrix
Switch, connect a CAT5e cable between the Daisy Chain Ports of iMatrix
Switch 2 and the Monitor Ports of iMatrix Switch 3 (see Figure 13).

Figure 13: Connecting Daisy Chained Monitor Ports
4. Connect the supplied Mini-DIN cable between daisy chaining Port OUT
of the Controller iMatrix Switch and daisy chaining Port IN of iMatrix
Switch Client 1.
If you are installing a third iMatrix Switch, connect the supplied Mini-DIN
cable between daisy chaining Port OUT of iMatrix Switch 2 and daisy
chaining Port IN of iMatrix Switch 3 (see Figure 14).

Using iMatrix Switch Web Manager
Overview
This chapter describes how to monitor and control individual iMatrix Switches
using Web Manager. The following topics are covered:
Accessing Web Manager
Status
Control
Conguration
The iMatrix Switch has built-in support for remote control from any computer with
an Internet browser and access to the iMatrix Switch’s IP address. Web Manager
is the browser-based interface that allows you to change settings, view status, and
retrieve data remotely.
Note:____________________________________________________________________
To access Web Manager, the Display option in the CLI must be set to ON. For
more information, see Using the Command Line Interface on page 8.
__________________________________________________________________________
Accessing Web Manager
Web Manager is a browser-based interface that provides access to an iMatrix
Switch that has an IP address accessible from the computer running Web Manager.
Web Manager supports all common browsers.
To access Web Manager:
1. Open an Internet browser on your computer.
2. Enter the iMatrix Switch’s IP address in the URL box and press Enter. The
default IP address is 10.60.0.123. The Web Manager page appears as shown in
Figure 15.
