Introduction
Thank you for choosing the 24-Port 10/100 + 2-Port
10/100/1000 Gigabit Advanced Smart Switch with 2
Combo SFPs.
The 24-Port 10/100 + 2-Port 10/100/1000 Gigabit Advanced
Smart Switch brings a whole new level of intelligence and
security to the network infrastructure at a cost effective
price. It offers 24 10/100 Ethernet (copper) ports with two
10/100/1000 Gigabit Ethernet copper or optional optical
(SFP) interfaces for uplinking connected users to the core
network.
The 24-Port 10/100 + 2-Port 10/100/1000 Gigabit
Advanced Smart Switch is able to secure the network
through 802.1X port authentication and MAC filtering.
802.1X requires clients to authenticate themselves before
the port will pass data.
Introduction
The Switch’s extensive QoS features makes the solution
ideal for real-time applications like voice and video. The
four priority queues together with Weighted Round Robin
and Strict Priority scheduling techniques let network
administrators quickly prioritize real-time voice and video
traffic over data traffic. Individual users or applications
can also be prioritized above others using various Class of
Service options - by port, Layer 2 priority (802.1p), and Layer
3 priority (IP Precedence or DSCP). Intelligent broadcast,
multicast, and unknown unicast storm control minimizes
and contains the effects that these types storms have on
regular traffic. IGMP Snooping limits bandwidth-intensive
video traffic to only the requestors without flooding to all
users. Incoming traffic can be policed and outgoing traffic
can be shaped allowing network administrators to control
network access and traffic flow.
The Switch also includes features for network expansion
and faster throughput performance. Link aggregation
enables network administrators to create multiple highbandwidth trunks between switches. This provides a level
of reliability because the system will continue to operate if
one of the links breaks. Spanning Tree (STP), Fast Spanning
Tree, and Rapid Spanning Tree (RSTP) allow admins to
build a mesh of switches increasing the availability of the
system.
The simplified user interface provides an intuitive, secure
management platform enabling admins to better utilize
the comprehensive feature-set of the switch, resulting in
a better optimized, more secure network.

Ethernet 1-24 These RJ-45 ports support
network speeds of either 10 Mbps or 100 Mbps,
and can operate in half and full-duplex modes.
Auto-sensing technology enables each port to
automatically detect the speed of the device
connected to it (10 Mbps or 100 Mbps), and
adjust its speed and duplex accordingly.
To connect a device to a port, you will need to
use Category 5 (or better) network cable.
Ethernet G1-G2 The Switch is equipped with
two Gigabit RJ-45 ports that are shared with
two miniGBIC ports. If a Gigabit miniGBIC port is
being used, the associated RJ-45 port (Gigabit 1
or Gigabit 2) cannot be used.
Both ports support auto-negotiation, so the
optimum transmission mode (half or full duplex)
and data rate (10, 100, or 1000 Mbps) can be
selected automatically, if this feature is also
supported by the attached device. If a device
connected to one of these ports does not support
auto-negotiation, the communication mode of
that port can be configured manually.
Each port also supports IEEE 802.3.x
auto-negotiation of flow control, so the Switch
can automatically prevent port buffers from
becoming saturated.
These ports support automatic MDI/MDI-X
operation, so you can use straight-through cables
for all network connections to PCs, servers, or
additional switches.
MiniGBIC (1-2) The Switch is equipped with
two miniGBIC ports that have shared Gigabit
Ethernet ports (Gigabit 1 and Gigabit 2) which
provide for the installation of one expansion
module. These ports provide links to high-speed
network segments or individual workstations at
speeds of up to 1000 Mbps (Gigabit Ethernet).
To establish a Gigabit Ethernet connection using
a miniGBIC port, you will need to install a MGBT1,
MGBSX2, or MGBLH1 Gigabit expansion module
and use Category 5e cabling or fiber optic
cabling.
To establish a Fast Ethernet connection using a
miniGBIC port, you will need to install a MFEFX1
(100BASE-FX) or MFELX1 (100BASE-LX) 100SFP
Transceiver and use fiber optic cabling.
Reset The reset button can be accessed with
a straightened paper clip or similar object. The
reset button has two functions:

Pre-Installation Considerations
Full-Duplex Considerations
The Switch provides full-duplex support for its RJ-45
ports. Full-duplex operation allows data to be sent and
received simultaneously, doubling a port’s potential data
throughput. If you will be using the Switch in full-duplex
mode, the maximum cable length using Category 5 cable
is 328 feet (100 meters).
1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX
connections should also work for 1000Base-T, providing
that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any
new cable installations, Category 5e (enhanced Category
5) or Category 6 cable should be used. The Category
5e specification includes test parameters that are only
recommendations for Category 5. Therefore, the first
step in preparing existing Category 5 cabling for running
1000BASE-T is a simple test of the cable installation to be
sure that it complies with the IEEE 802.3ab standards.
Desktop Notebook Server
Typical Network Configuration
When you connect your network devices, make sure you
don’t exceed the maximum cabling distance of 100 meters
(328 feet).
Positioning the Switch
Before you choose a location for the Switch, observe the
following guidelines:
Make sure that the Switch is accessible and that the
•
cables can be connected easily.
Keep cabling away from sources of electrical noise,
•
power lines, and fluorescent lighting fixtures.
Position the Switch away from water and moisture
•
sources.
To ensure adequate air flow around the Switch, be
•
sure to provide a minimum clearance of two inches
(50mm).
Do not stack free-standing Switches more than four
•

Reduced Air Flow Installation of the equipment
•
in a rack should be such that the amount of air flow
required for safe operation of the equipment is not
compromised.
Mechanical Loading Mounting of the equipment in
•
the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
Circuit Overloading Consideration should be given
•
to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing
this concern.
Reliable Earthing Reliable earthing of rack-mounted
•
equipment should be maintained. Particular attention
should be given to supply connections other than
direct connections to the branch circuit (e.g. use of
power strips).

can be attached to a port belonging to any VLAN, as long
as that VLAN has been assigned an IP address.
IP Address Address of the VLAN interface that is allowed
management access. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods. (Default:
192.168.1.254)
Subnet Mask This mask identifies the host address
bits used for routing to specific subnets. (Default:
255.255.255.0)
Default Gateway IP address of the gateway router
between this device and management stations that exist
on other network segments. (Default: 0.0.0.0)
Setup > Time
Simple Network Time Protocol (SNTP) allows the Switch
to set its internal clock based on periodic updates from a
time server (SNTP or NTP). Maintaining accurate time on
the Switch enables the system log to record meaningful
dates and times for event entries. If the clock is not set, the
Switch will only record the time from the factory default
set at the last boot up. When the SNTP client is enabled,
the Switch periodically sends a request for a time update
to a configured time server.
MAC Address Physical address of a device mapped to
this interface.
IP Configuration
IP Address Mode Specifies whether IP functionality is
enabled via manual configuration (Static) or dynamically
using Dynamic Host Configuration Protocol (DHCP).
NOTE: If DHCP is enabled, IP will not function
until a reply has been received from the server.
Requests will be broadcast periodically by the
Switch for an IP address. If the mode is set to
DHCP and a server is not available, you can
reconfigure the settings by connecting the
console interface directly to a computer.
Select the IP Address Mode using the drop-down
menu. Selecting Static will allow you to enter a static
IP address, subnet mask and default gateway using the
text field provided. Selecting DHCP disables these text
fields and the Switch attempts to obtain an IP address
automatically from a DHCP server. The default setting is
Static.
Management VLAN ID of the configured VLAN (1-4094,
no leading zeroes). By default, all ports on the Switch are
members of VLAN 1. However, the management station

Port Management
Port functionality can be controlled using the Port
Management settings. Speeds, duplex, and grouping can
be defined.
Port Management > Port Settings
You can manually configure the speed, duplex mode, and
flow control used on specific ports, or use autonegotiation
to detect the connection settings used by the attached
device. Use the full-duplex mode on ports whenever
possible to double the throughput of switch connections.
Flow control should also be enabled to control network
traffic during periods of congestion and prevent the loss
of packets when port buffer thresholds are exceeded. The
Switch supports flow control based on the IEEE 802.3x
standard.
