Hardware Description
This section describes the hardware of the MIL-SEM24T4GPA Switch.
Physical Dimension
The physical dimensions of the MIL-SEM24T4GPA Switch are 440mm(W) x
161mm(D) x 44mm(H)
Front Panel
The Front Panel of the MIL-SEM24T4GPA Switch consist of 24 x auto-sensing
10/100/1000Mbps Ethernet RJ-45 ports (automatic MDI/MDIX), 4 SFP ports, and
the LED indicators are also located on the front panel of the switch.
Front Panel of the 20 10/100/1000T + 4 10/100/1000T/Mini-GBIC Combo SNMP Lite Managed
Switch
RJ-45 Ports (Auto MDI/MDIX): 24 10/100/1000 auto-sensing for 10Base-T
or 100Base-TX or 1000Base-T connections.
In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX means
that you can connect to another Switch or workstation without changing
non-crossover or crossover cabling.
4 SFP ports: 4 automatic detect Giga fiber ports. Giga fiber is the SFP
module.

Rear Panel
The 3-pronged power plug is located at the Rear Panel of the MIL-SEM24T4GPA
Switch as shown in figure. The Switches will work with AC in the range 100-240V
AC, 50-60Hz.
Rear Panel of the MIL-SEM24T4GPA Switch
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.
Make sure there is enough clearance around the Switch to allow attachment of
cables, power cord and air circulation.
Attaching Rubber Feet

13
1. Make sure mounting surface on the bottom of the Switch is grease and dust
free.
2. Remove adhesive backing from your Rubber Feet.
3. Apply the Rubber Feet to each corner on the bottom of the Switch. These
footpads can prevent the Switch from shock/vibration.
Power On
Connect the power cord to the power socket on the rear panel of the Switch. The
other side of power cord connects to the power outlet. The internal power works
with AC in the voltage range 100-240VAC, frequency 50~60Hz. Check the power
indicator on the front panel to see if power is properly supplied.

14
Network Application
This section provides you a few samples of network topology in which the switch
is used. In general, the MIL-SEM24T4GPA Switch is designed to be used as a
desktop or segment switch.
Desktop Application
The MIL-SEM24T4GPA Switch is designed to be a desktop size switch that is an
ideal solution for small workgroup. The Switch can be used as a stand-alone
switch to which personal computers, server, printer server are directly connected
to form small workgroup.
Segment Application
For enterprise networks where large data broadcast are constantly processed,
this switch is suitable for department user to connect to the corporate backbone.
User can connect PCs, workstations, and servers to each other via the
MIL-SEM24T4GPA Switch. All the devices in this network can communicate with
each other. Connecting servers to the backbone switch allow other users to
access the data of server.
The switch automatically learns node address, which are subsequently used to
filter and forward all traffic based on the destination address. User can use any of
the RJ-45 port of the MIL-SEM24T4GPA Switch to connect with another Switch or
Hub to interconnect each of user’s small-switched workgroups to form a larger
switched network.

15
Console Management
Connecting to the Console Port
Use the supplied RS-232 cable to connect a terminal or PC to the console port.
The connected terminal or PC must support the terminal emulation program.
Connecting the switch to a terminal via RS-232 cable
Login in the Console Interface
When the connection between Switch and PC is ready, turn on the PC and run a
terminal emulation program or 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
Flow control: None

16
The settings of communication parameters
After finishing the parameter settings, click “OK“. When the blank screen shows
up, type in “root” then press enter button to get into command line mode. Please
see below figure for login screen.
CLI command interface

17
CLI Management
The system supports console management (CLI command). After you login to the
system, you will see a command prompt.

Web-Based Management
This section introduces the configuration and functions of the Web-Based
management.
About Web-based Management
On CPU board of the switch, there is an embedded HTML web site residing in
flash memory, which offers advanced management features and allow users to
manage the switch from anywhere on the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0 or later version. And,
it is applied for Java Applets for reducing network bandwidth consumption,
enhance access speed and present an easy viewing screen.
[NOTE] By default, IE5.0 or later version does not allow Java Applets to activate
sockets. The user has to explicitly modify the browser setting to enable Java
Applets to operate network ports.
Preparing for Web Management
Before using web management, install the switch on the network and make sure
that any one of the PCs on the network can connect with the switch through the
web browser. The switches default value of IP, subnet mask and password are as
below:
IP Address: 192.168.1.77
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
Password: root

System Login
The default values are as below:
IP Address: 192.168.1.77
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
Password: root
Login Interface
System Configuration
System parameters information list as below, and the other parameters of system
can be configured as well.
MAC Address: the unique hardware address assigned by manufacturer
(default)

20
S/W Version: the Software Version of Kernel
H/W Version: the Hardware Version of Switch
Active IP Address: the current IP Address
Active Subnet Mask: the current IP Subnet Mask
Active Gateway: the current Gateway
DHCP Server: the DHCP Server IP Address
Lease Time Left: the DHCP lease time. After 50% of the lease time has
passed, the client/switch will attempt to renew the lease with the original
DHCP server that it obtained the lease from using a DHCPREQUEST
message. Any time the client/switch boots and the lease is 50% or more
passed, the client/switch will attempt to renew the lease. At 87.5% of the
lease completion, the client/switch will attempt to contact any DHCP server
for a new lease
