Introduction

The MIL-SM2401M managed switch is an ideal solution for applying
services at the edge of the network infrastructure. It provides wire-speed,
Fast Ethernet switching providing high-performance data transfer. The
switch features a store-and-forward architecture with auto-learning of
source addresses with an 8K-entry MAC address table.

Figure 1-1. The MIL-SM2401M switch

The switch provides 24 switched 10/100Mbps Fast Ethernet UTP ports
and one dual port module. The module offers a broad selection of
10/100/1000 Mbps ports in either UTP or Fiber optics.

With built-in Web-based Management, managing and configuring the
switch is simplified. The Web Browser may be used to configure and
manage the network, from cabinet level management to port level control
and monitoring. Use of a mouse replaces typing of command strings.
The switch can also be managed via Telnet, Console, or SNMP
Management.

Management Methods

The MIL-SM2401M switch series support the 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 switch in this method requires a direct connection between
a PC and the switch. Telnet management requires a network connection.
The default IP address is 192.168.1.77 with a subnet mask of

255.255.255.0. This default address can be used to login and change
the configuration using Telnet.

4

Web-based Management

The switch provides an embedded HTML web server residing in flash
memory. It offers advanced management features and allows users to
manage the switch from anywhere on the network through a standard
browser such as Microsoft Internet Explorer or Netscape.

SNMP Network Management

SNMP (Simple Network Management Protocol) provides a means to
monitor and control network devices, and to manage configurations,
statistic collection, performance, and security.

Hardware Description

Front Panel

The Front Panel of the MIL-SM2401M switch series consists of 24
100Mbps Fast Ethernet ports, one module bay, one console port, one
LED-Indicator for Power, and two LED-Indicators (LNK/ACT, FDX/COL)
for each UTP port.

Console LED Fast Ethernet Ports Module Bay

 100BASE-TX UTP Ports: The MIL-SM2401M comes with 24

100Mbps Fast Ethernet UTP ports.



Modules: The MIL-SM2401M a broad range of modules. Check

with your MiLAN sales representative for details.

 Console Port: Console management can be done through the

Console Port. It requires a direct connection between the switch and
an end station (PC) via a RS-232 cable.

LED Indicators

The LED Indicators give real-time information of systematic operation
status. The following table provides descriptions of LED statuses and
their meaning.

Rear Panel

The 3-pronged power plug and ventilation fan are located at the rear
panel of the MIL-SM2401M as shown in Figure 2-3. The Switch will work
with AC in the range 100-240V AC, 50-60Hz

.

Desktop Installation

Set the switch on a sufficiently large flat space with a power outlet
nearby. The surface where you put your switch should be clean, smooth,
level, and sturdy. Provide enough clearance around the switch to allow
attachment of cables, power cord and air circulation.

Attaching Rubber Feet

A. Make sure the mounting surface on the bottom of the Switch is

grease and dust free.
B. Remove adhesive backing from the rubber feet.
C. Apply the rubber feet to each corner on the bottom of the switch.

These footpads can prevent the Switch from shock/vibration.

Figure 2-4. Attaching Rubber Feet to each corner on the bottom of the Switch

9

Rack-mounted Installation

The MIL-SM2401 comes 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:

A. 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 2-4. Attach mounting brackets with screws

10

B. After attaching both mounting brackets, position the MIL-SM2401M

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 a screwdriver
and the rack-mounting screws.

Figure 2-5. Mount the MIL-SM2401M in an EIA standard 19-inch Rack

Note: For proper ventilation, allow 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.

Power On

Connect the power cord to the power socket on the rear panel of the
Switch. Connect the other end of the cord to an appropriate power outlet.
The internal power supply in the switch works with AC in the voltage
range 100-240VAC, frequency 50~60Hz.

Press the power On/Off switch to the On position and check the power
indicator on the front panel to see if power is properly supplied.

Network Application

Segment Application

For enterprise networks where large data broadcasts are constantly
processed, this switch is suitable for department users to connect to the
corporate backbone.

You can use the MIL-SM2401M switch to connect PCs, workstations,
and servers to each other by connecting these devices directly to the
switch. The modular ports can also connect to an upstream network
device.

You can use the optional Fiber ports in the dual port module bay of the
MIL-SM2401M to connect with another Switch or Hub to interconnect
each of your small, switched workgroups to form a larger and long
distance switched network.

Figure 3-1. Use the MIL-SM2401M switch ports to connect multiple devices in the

segment.

12

Segment Bridge

For larger structured networks, this switch is an ideal solution for
department users to connect to the corporate backbone.

In the illustration below, two Ethernet switches with PCs and print server,
and a local server are connected to the MIL-SM2401M. The devices in
this network can communicate with each other through the MIL­SM2401M. Connecting servers to the Switch allows other users to
access the server’s data.

Network Configuration

Connecting a Terminal or PC to the Console Port

Console management involves the administration of the switch via a
direct connection to the RS-232 console port. This port is a female DB-9
connector. From the main menu of the console program, the user has
access to manage the functions of the switch.

Figure 4-1. Connecting the switch to a terminal via RS-232 cable

Use the supplied RS-232 cable to connect a terminal or PC to the
console port. The terminal or PC to be connected must support the
terminal emulation program.

14

After the connection between Switch and PC is finished, turn on the PC
and run a terminal emulation program or Hyper Terminal to match the
following default characteristics of the console port:

Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bits: 1
Flow Control: None

Figure 4-2. The settings of communication parameters

After you have entered the parameter settings, press the Enter Key and
the Main Menu of console management appears.

15

Console – Menu

1. The switch also provides a serial interface to manage and monitor the
switch. The user can follow the Console Port Information provided by
the web to use the Windows HyperTerminal program to link the
switch.

2. Type the user name and password to login. The default user name is
root; the default password is root.

3. The timeout on the console port is 60 seconds. If no action is taken
on the console screen for one minute, the program reverts back to the
logon screen and a new login is necessary in order to continue.

4. The switch is shipped with a default IP address of 192.168.1.77. The
default subnet mask is 255.255.255.0.
