1. Introduction
The 3-slot Modularized Fast Ethernet L2 plus + 2 Gigabit Copper / Mini-GBIC Combo
Managed Switch is a modular Ethernet switch that can be used to build
high-performance switched workgroup networks. This switch is a store-and-forward
device that offers low latency for high-speed networking. The Switch is targeted at
workgroup, department or backbone computing environments.
The 3-slot Modularized Fast Ethernet L2 plus + 2 Gigabit Copper / Mini-GBIC Combo
Managed Switch features a ―store-and-forward‖switching scheme. This allows the
switch to auto-learn and store source address in an 8K-entry MAC address table.
MDI (Medium Dependent Interface) Port is also called an "uplink port". The MDI port
does not cross transmitting and receiving lines, which is done by the regular ports
(MDI-X ports) that connect to end stations. In general, MDI means connecting to
another Hub or Switch while MDIX means connecting to a workstation or PC.
Therefore, Auto MDI/MDIX means you can connect to another Switch or workstation
without changing non-crossover or crossover cabling.
The 3-slot Modularized Fast Ethernet L2 plus + 2 Gigabit Copper / Mini-GBIC Combo
Managed Switch has 3 module slots. Users can purchase the modules on demand,
increasing elasticity of network application.

Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a network,
eliminated congestion problems inherent with CSMA/CD (Carrier Sense multiple
access with Collision Detection) protocol, and greatly reduced unnecessary
transmissions.
This revolutionized networking. First, by allowing two-way simultaneous transmissions
over the same port (Full-duplex) essentially doubled the bandwidth. Second, by
reducing the collision domain to a single switch-port eliminated the need for carrier
sensing. Third, by using the store-and-forward technology‘s approach of inspecting
each packet to intercept corrupt or redundant data eliminated unnecessary
transmission that slow the network. By employing address learning replaced the
inefficient receiving port.
Auto-negotiation regulates the speed and duplex of each port, based on the capability
of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps
node without loss of data. Auto-negotiation and flow-control may require disablement
for some networking operations involves legacy equipment. Disabling the
auto-negotiation is accomplished by fixing the speed or duplex of a port.
Ethernet Switching Technology supplied higher performance at costs lower than other
solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching
is replacing expensive routers and inefficient hubs as the ultimate networking solution.
Switching brought a whole new way of thinking to networking.

Rear Panel
Equipped with a 3-pronged power plug for AC power input and a 14-pin dual-row
connector for DC power input, the Ethernet switch allows users to supply AC power in
the range of 100 to 240V/50-60Hz or DC power in the range of 12 to 48V for redundant
supplying purposes.
The Rear Panel of the 3-slot intelligent chassis switch
Note: As the photo shown below, the DC power terminal (male) should be connected
with a 2x7-pin, pitch 4.2 mm Mini Fit connector.
Pinouts of the DC Power Connector

10
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
allow air circulation.
Attaching Rubber Feet
A. Make sure 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.

Rack-mounted Installation
The 3-slot intelligent chassis switch 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

11
with the smaller bracket screws. Then attach the remaining bracket to the other
side of the Switch.
Attach mounting brackets with screws
B. 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 a screwdriver and the rack-mounting screws.
Mount the Switch in 19‖ 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.

12
Power On
Connect the 3-prong AC power cord or the 14-pin 2-row DC power cable to the power
socket at the rear panel of the Ethernet switch. The Ethernet switch can work with AC
power in the voltage range of 100-240V/50~60Hz or 12-48VDC. The AC and DC inputs
can be used for redundant power supply. If one of the power inputs fails, the other one
is able to keep providing power to the Ethernet switch. Check the power LED indicator
on the front panel to see if power is properly supplied.
Redundant power
Connect the optional redundant power cord to the redundant power socket on the rear
panel of the Switch. The other side of redundant power cord connects to the power
supply. The Switch works with power supply of 12-48 VDC.
Please make sure the connection on power supply is correct when using the optional
redundant power cord. Red cord should be connected to ―+‖ and black cord should be
connect to ―-‖.

3. Network Application
This section provides you a few samples of network topology in which the Switch is
used. In general, the 3-slot intelligent chassis switch is designed as a segment switch.
That is, with its large MAC address table (8K-entry) and high performance, it is ideal for
interconnecting networking segments.
PCs, workstations, and servers can communicate each other via the 3-slot intelligent
chassis switch. The switch automatically learns node addresses, which are
subsequently used to filter and forward all traffic based on the destination address.
By using the Gigabit mini-GBIC port for long distance up-link, the switch can connect
with another switch or hub to interconnect other small-switched workgroups to form a
larger switched network. The figure below is an example application topology.
The example of application topology

14
Connecting to the Switch
The Console port is a female DB-9 connector that enables a connection to a PC or
terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with
a male DB-9 connector to connect a terminal or PC to the Console port.
The Console configuration (out of band) allows you to set Switch for remote terminal as
if the console terminal were directly connected to it.

15
4. Console Management
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
Control flow: None
The settings of communication parameters
After finishing the parameter settings, click ―OK―. When the blank screen shows up,
press Enter key to bring out the login prompt. Key in the ―root―(default value) for the
both User name and Password (use Enter key to switch), then press Enter key and the
Main Menu of console management appears. Please see below figure for login screen.

Module Hot-Swapping
The 3-slot Modularized Fast Ethernet L2 plus + 2 Gigabit Copper / Mini-GBIC Combo
Managed Switch supports module hot-swapping. User can insert or pull the module out
of the slot without powering down the switch. Once the module is not fully inserted, the
LEDs on the module panel will all light on at the same time. Meanwhile, the switch also
sends warning message to the connected PC, work station or terminal via console port.
Please see the picture as below for reference.
