4xN 10/100/1000 Span Port iMatrix Switch
Chapter 1
Introduction
Overview
Net Optics 4xN 10/100/1000 Span Port iMatrix Switches enhance LAN vis-
ibility by providing access across multiple 10/100/1000 Span ports for up to
four analyzers or security devices. 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 4xN 10/100/1000 Span iMatrix Switch supports simultaneous passive
monitoring of any four 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 monitoring device or host PC to manage
up to three iMatrix Switches and 48 Span ports.
Remote Control
The iMatrix Switch Web Manager and System Manager allows you to remote-
ly 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. System Manager
is an SNMP-based management interface.
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.

LED Indicators
Monitor Port LEDs: Each Monitor Port has a 2-character LED that shows
the number of the Span port currently connected to the monitor port.
Link/Activity Indicator: If a good link is established, the LED illuminates a
steady green. If there is current activity on this link, the LED flashes.
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.
PWR 1/ PWR 2: Main and Redundant Power. If the Tap is deployed with
both power supplies, 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.

Chapter 2
Installing the iMatrix Switch
Overview
The procedure for installing the iMatrix Switch follows these basic steps:
Plan the installation
Configure IP parameters
Mount the iMatrix Switch
Connect the Management Port
Connect to the network
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:
Single iMatrix Switch Mode
• A single monitoring device to controls the Monitor Ports of a single
iMatrix Switch from one COM Port.
Daisy Chaining Mode
Allows up to three iMatrix Switches to be controlled from one monitoring
device or host PC.
Remote Access
The remote access features require 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 control the iMatrix Switch over WAN, you can also set
a gateway and IP address where you plan to use the SNMP management tool.

4xN 10/100/1000 Span iMatrix Switch
Configuring the iMatrix Switch
The iMatrix Switch is configured 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 Ports 1-4: Gigabit
CLI username: netoptics
CLI password: netoptics
You can set all parameters, check status, and control Monitor Port connections
from the Command Line Interface. You can change most settings later from
one of the remote interfaces.
Using the Command Line Interface (CLI)
All configuration 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 DB-9 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 CAT5e straight-through cables.
2. Repeat Step 1 for each additional network switch Span port you wish to
monitor.
Figure 4: Connecting Span Ports
Connecting to the Monitoring Device
You need to connect the iMatrix Switch to the input ports (NICs) of the moni-
tor device and connect Control Port 2 to a COM port on the monitoring device
or computer where you access the CLI.
1. Verify that the DIP switch located on the rear of the unit is set as shown in
Figure 5 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 the monitoring ports to one device or separate devices.
In a daisy chain configuration, 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 traffic 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
sections.
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. Configure and install the Controller iMatrix Switch as described in the
preceding 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 9. If you are install-
ing a third switch, set the DIP switch as shown in Figure 9 for Client 2.
3. Connect CAT5e cables between the Daisy Chain Ports of iMatrix Switch 1
and the Monitor Ports of iMatrix Switch 2. If you are connecting a third
iMatrix Switch, connect CAT5e cables between the Daisy Chain Ports of
iMatrix Switch 2 and the Monitor Ports of iMatrix Switch 3 (see Figure 9).

Figure 9: Connecting Daisy Chained Monitor Ports
4. Connect the supplied Mini-DIN cable between Daisy Chain Port OUT of
the Controller iMatrix Switch and Daisy Chain Port IN of iMatrix Switch
Client 1.
If you are installing a third iMatrix, connect the supplied Mini-DIN cable
between Daisy Chain Port OUT of iMatrix Switch 2 and Daisy Chain Port
IN of iMatrix Switch 3 (see Figure 10).

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
Viewing iMatrix Switch Status
Controlling iMatrix Switch Connections
Configuring the iMatrix Switch
Web Manager is the browser-based interface that allows you to change configu-
ration settings, view status, and control which Span ports are connected to the
monitoring devices.
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 4.
__________________________________________________________________________
Accessing Web Manager
Web Manager is a browser-based interface that provides access to any iMatrix
Switch with 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 11.
