SWITCH
ARCHITECTURE
The switch performs a wire-speed, non-blocking switching fabric.
This allows wire-speed transport of multiple packets at low
latency on all ports simultaneously. The switch also features
full-duplex capability on all ports, which effectively doubles the
bandwidth of each connection.
This switch uses store-and-forward technology to ensure
maximum data integrity. With this technology, the entire packet
must be received into a buffer and checked for validity before
being forwarded. This prevents errors from being propagated
throughout the network.
NETWORK
MANAGEMENT
OPTIONS
The switch can also be managed over the network with a web
browser or Telnet application. The switch includes a built-in
network management agent that allows it to be managed in-
band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also
has an RJ45 console port connector on the front panel for out-
of-band management. A PC may be connected to this port for
configuration and monitoring out-of-band via a serial cable.
NOTE: For a detailed description of the management
features, refer to the software manual.

DESCRIPTION OF HARDWARE
1000BASE-T PORTS The switch contains ten 1000BASE-T RJ-45 ports. All RJ-45
ports support automatic MDI/MDI-X operation, auto-negotiation
and IEEE 802.3x auto-negotiation of flow control, so the
optimum data rate and transmission is selected automatically.
SFP TRANSCEIVER
SLOTS
MS453526M supports the Small Form Factor Pluggable (SFP)
transceiver slots are port 9 and 10. In the default configuration,
if an SFP transceiver (purchased separately) is installed in a slot
and has a valid link on the port, the associated RJ-45 port is
disabled.
PORT AND SYSTEM
STATUS LEDS
The MS453526M switch includes a display panel for system and
port indications that simplify installation and network
troubleshooting. The LEDs, which are located on left hand side
of the front panel for easy viewing. Details are shown below and
described in the following tables.

NETWORK PLANNING
INTRODUCTION TO
SWITCHING
A network switch allows simultaneous transmission of multiple
packets; it can partition a network more efficiently than bridges
or routers. Therefore the switch has been recognized as one of
the most important devices for today’s networking technology.
When performance bottlenecks are caused by congestion at the
network access point such as file server, the device can be
connected directly to a switched port. In addition, by using full-
duplex mode, the bandwidth of the dedicated segment can be
doubled to maximize throughput.
When networks are based on repeater (hub) technology, the
distance between end stations is limited by a maximum hop
count. However, a switch can subdividing the network into
smaller and more manageable segments, and linking them to
the larger network than it turns the hop count back to zero and
removes the limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet,
or Gigabit Ethernet network to significantly increase bandwidth
while using conventional cabling and network cards.
APPLICATION
EXAMPLES
The MS453526M Switch implements 8 Gigabit Ethernet TP ports
with auto MDIX and 2 slots for the removable SFP module which
supports comprehensive types of fiber connection, such as LC
and BiDi-LC modules. It is not only designed to segment your
network, but also to provide a wide range of options in setting
up network connections. Some typical applications are
described below.
The switch is suitable for the following applications.
 Remote site application is used in Enterprise or SMB
 Peer-to-peer application is used in two remote offices
 Office network
 High Performance Requirement environment
 Advance Security for network safety application
 Suitable for data/ voice and video conference application

INSTALLING THE SWITCH
SELECTING A SITE The switch can be mounted in a standard 19-inch equipment
rack (Via Optional Rack mount Kit) or on a flat surface. Be
sure to follow the guidelines below when choosing a location.
◆ The site should:
 Be at the center of all the devices you want to link and
near a power outlet.
 Be able to maintain its temperature within 0 to 45°C
and its humidity within 10% to 90%, non-condensing.
 Be accessible for installing, cabling and maintaining
the devices.
 Allow the status LEDs to be clearly visible.
◆ Make sure the twisted-pair Ethernet cable is always routed
away from power lines, radios, transmitters or any other
electrical interference.
◆ Make sure that the switch MS453526M is connected to a
separate grounded power outlet that provides 100 to 240
VAC, 50 to 60 Hz.
ETHERNET CABLING To ensure proper operation when installing the switch into a
network, make sure that the current cables are suitable for
100BASE-TX or 1000BASE-T operation. Check the following
criteria against the current installation of your network:
◆ Cable type: Unshielded twisted pair (UTP) or shielded
twisted pair (STP) cable with RJ-45 connectors; Category 5
or Category 5e with maximum length of 100 meters is
recommend 100BASE-TX, and Category 5e or 6 with
maximum length of 100 meters is recommend for
1000BASE-T.
◆ Protection from radio frequency interference emissions.
◆ Electrical surge suppression.
◆ Separation of electrical wires and data based network wiring.
◆ Safe connections with no damaged cables, connectors or
shields.

NOTE: SFP transceivers are not provided in the switch
package.
CONNECTING TO A
POWER SOURCE You can plug or remove power cord from AC power socket, to
switch the power on and off.
Inserting the Power Cord to AC Power Socket
Step1. Insert the power cable plug directly into the AC Socket located at the back of
the switch.
Step2. Plug the other end of the cable into a grounded, 3-Pin, AC power source.
Step3. Check the front-panel LEDs as the device is powered on to be sure the POWER
LED is lit. If not, check that the power cable is correctly plugged in.
WARNING: For International use, you may need to change the
AC line cord. You must use a line cord set that has been
approved for the socket type in your country.

MAKING NETWORK
CONNECTIONS
CONNECTING
NETWORK
DEVICES
The switch is designed to be connected to 10, 100 or
1000Mbps network cards in PCs and servers, as well as
to other switches and hubs. It may also be connected to
remote devices using optional SFP transceivers.
TWISTED-PAIR
DEVICES
Each device requires an unshielded twisted-pair (UTP)
cable with RJ-45 connectors at both ends. Use category
5, 5e or 6 cables for 1000BASE-T connections, category
5 or better for 100BASE-TX connections.
CABLING GUIDELINES
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration,
so you can use standard straight-through twisted-pair cables to connect to any
other network device (PCs, servers, switches, routers, or hubs).
CAUTION:
Do not plug a phone jack connector into an
RJ-45 port. This will damage the switch.
CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES
Step1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.
