Management Methods
The 24 Port SNMP Managed Switch supports following management methods:
• Console and Telnet Management
• Web-based Management
• SNMP Network Management
Console and Telnet Management
Console Management is done through the RS-232 Console Port. Managing the 24 Port
SNMP Managed Switch in this method requires a direct connection between PC and the 24
Port SNMP Managed Switch. While Telnet management is done over the network. Once the
24 Port SNMP Managed Switch is on the network, you can use Telnet to log in and change
the configuration. The automatic log-out times can be programmed and are detailed on pages
36 and 56. See page 12 for details.
Web Based Management
The switch can be managed using a standard web browser that supports Java applets. This
interface has the same functionality as the console/Telnet interfaces but is more user-friendly.
See page 38 for details.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means to monitor and control a
network device, and to manage configurations, statistic collection, performance and security.
Data is passed from SNMP agents, which are hardware & software processes reporting
activity in each network device to the workstation console used to oversee the network. The
agent returns information contained in a MIB (Management Information Base), which is a data
structure that defines what is obtainable from the device and what can be controlled.

Diagnostic Test
After the installation is completed and AC power is applied to the Switch, the system will
automatically perform a diagnostic test. If a console session is active at this time then it is
possible to see each stage of this start-up and test procedure as it is carried out.
This procedure will take up to 5 minutes to complete. Upon completion the switch will start in
a default condition and begin to pass traffic.

Installation
.
Pre-Installation Requirements
Before you start hardware installation, make sure your installation environment has below
items:
PC with 10/100Mbps Ethernet NICs / 100Mbps Fiber NICs:
Your PC must have a standard Ethernet RJ-45 interface to connect to the Switches copper
port.
UTP cable with RJ45 connectors: Ensure that you use a tested cable.
AC Power: 100 to 240V AC at 50/60 Hz: Make sure that the power is accessible and the
AC power cable can be and disconnected and connected easily.
Dedicated power supply: Use dedicated AC or power conditioners to supply reliable
electrical power to the network devices.
A dry cool place: Keep the Switch away from moisture. Avoid direct sunlight, sources of
heat, and a high amount of electromagnetic interference.
Mounting tools: If you intend to mount the Switch in a rack, make sure you have all the
tools, mounting brackets, screws etc.
Caution:
Cabling must be away from sources of electrical noise such as radio, computers, transmitters,
broadband amplifiers, power lines etc.
Airflow around the Switch and through its vents on the rear must not be restricted.
Mounting the Switch
The 24 Port SNMP Managed Switch is suitable for use in an office environment where it can
be rack-mounted in standard EIA 19-inch racks or standalone.
Desktop Mounting
Set the Switch on a sufficiently large flat space with a power outlet nearby, and near the
center of all networked devices.
Make sure mounting surface on the bottom of the Switch is grease dust free.
Remove adhesive backing from your Rubber Feet.
Figure 3-1. Attaching Rubber Feet to each corner on the bottom of the
Switch
Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads can
prevent the Switch from shock/vibrations.
Caution: Do not place objects on top of the Switch.

Rack-mounted Installation
The 24 Port SNMP Managed Switch is supplied with a rack-mounted kit and can be mounted
in an EIA standard size, 19-inch rack. The Switch can be placed in a wiring closet with other
equipment.
Perform the following steps to rack mount the Switch:
Position one bracket to align with the holes on one side of the Switch and secure it with the
smaller bracket screws. Then attach the remaining bracket to the other side of the Switch.
Figure 3-2. Attach mounting brackets with screws
After attaching both mounting brackets, position the switch in the rack by lining up the holes in
the brackets with the appropriate holes on the rack. Secure the switch to the rack with the
rack-mounting screws.
Figure 3-3. Mount the 24TP+1Fiber Module Switch in an EIA standard 19inch Rack
Note: For proper ventilation, allow about at least 4 inches (10 cm) of clearance on the front
and 3.4 inches (8 cm) on the back of the Switch. This is especially important for enclosed rack
installation.

Connecting to the Switch
The Console port is a male DB-9 connector located on the front panel of the switch that
enables a connection to a PC or terminal for monitoring and configuration. Use the supplied
RS-232 cable with a female DB-9 connector to connect a terminal or PC to the Console port.
The Console configuration allows you to program the Switch to enable a user at a remote
location to communicate with the unit as if the console terminal were directly connected.

Quick Start Guide
If you do not need to apply VLANs, Quality of Service, adjust any settings or manage the
switch via the network, then the switch can be used “straight-from-the-box” to carry network
traffic. In that case, no further action is needed. If you want to use the management settings
or controls, then a little work is needed to configure the switch.
1. After the installation is completed and AC power is applied to the switch, the unit will
automatically perform a diagnostic test. The switch loads its operating code from memory
and performs a full power-on self test. The screen will display the self-test progress, but
do not press any keys at this stage. This power-up sequence takes approx. 90 seconds to
complete. The web interface will take a further 30 seconds to become operational.
2. Configure you PC terminal emulation program such as HyperTerminal to allow it to
communicate with the switch via the supplied serial cable connected to the front panel
Console port. Set the emulation program for 9600, 8, No Parity, No Flow Control. See
page 12 for details
3. When the password and user name prompt is displayed, use the default username of
root in lower case letters. Use the password root. The main menu screen will be
displayed. Use either cursor keys or the tab key to navigate up and down the menu.
Select the item using the <CR> key. The <ESC> key will return you to the previous menu
level.
4. If the switch is to be managed over the LAN using the Telnet, SNMP or the web browser
functions, then an IP address is to be assigned to the switch. See page 14 for details. If
the switch is not being managed over the LAN, then go to page 12 below.
5. Once an IP address has been assigned to the switch, it should be possible to PING the
switch over the network. This will prove that the switch is present and responding
correctly to network requests. See page …. For details.
6. Now that the switch can be accessed over the network, use a browser application to open
up the configuration screens. Enter the switch IP address into the browser Address
window and use the same user name and password set as in 3 above.
7. Using the preferred method (console, Telnet or web browser), configure the switch to
meet your network requirements. Always save the configuration at the end of each action.
8. If you need to revert the switch back to the factory default configuration, then see page 36
or page 55.

Management Using The Console
Configuring the Console Interface
When the connection between Switch and PC is complete, turn on the PC and run a terminal
emulation program such as Hyper Terminal and configure its communication parameters to
match the following default characteristics of the console port:
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Control flow: None

8. The changes that have been made will only appear in the “New” column but not in the
current column, to activate the new settings and make them current the switch will
need restarting. See section 5.1 for how to restart switch.
After restarting the switch it is advisable to check that changes have been made current by
checking the network configuration menu again.
The following menu options enable detailed changes to the serial port and SNMP
configuration. These menus are not used in most instances.
