Introduction
Chapter 1: Introduction
Thank you for choosing the Linksys Business Series Smart
Gigabit Ethernet Switch.
The new Linksys Business Series Smart Gigabit Ethernet
Switches are cost-effective switching solutions ideal
for small businesses, the network edge, or workgroups
within larger organizations. These easy-to-install, highspeed switches offer many of the same Quality of Service
and Security features found in more expensive full Layer
2 managed switches but without their complexity. The
Smart Switches offer the following interfaces:
The SLM2024 and SLM2048 offer twenty four (24) or
•
forty eight (48) 10/100/1000 Gigabit copper ports, with
two (2) shared copper or optical (SFP) uplink interfaces
for connecting the switch to the core network.
The SLM224G, SLM224P, SLM248G, and SLM248P
•
offer twenty four (24) or forty eight (48) 10/100 copper
ports, with two (2) shared Gigabit copper or optical
(SFP) uplink interfaces for connecting the switch to the
core network.
The Smart Switch’s simplified user interface is an intuitive
management tool enabling you to quickly utilize the
comprehensive feature-set of the switch, resulting in a
better optimized network.
For Wireless or VoIP deployments, the SLM224P and
SLM248P support the IEEE802.3af standard for Power over
Ethernet (PoE). This eliminates the need for additional
power cables and the need for a nearby power outlet,
thereby making installation simple and inexpensive,
allowing networking devices like cameras and Wireless
Access Points to be positioned in optimal locations like in
ceilings and walls -- even outdoors.
security by keeping sensitive data separated from other
workgroups on the network..
Network Security is an absolute requirement for any
business and preventing unauthorized access to the
company network is business-critical. The Smart Switch
secures the network through 802.1X port authentication
which prompts end-users to provide their username
and password before they are permitted to pass data.
User access can also be controlled through the Smart
Switch’s MAC-Based Filtering capability which allows
network access only to those devices or workstations that
have been authorized as identified by their MAC (Media
Access Control) address. The Many-to-One or One-to-One
Port Mirroring feature of the Smart Switch enables you
to monitor the type of traffic being transmitted on the
network.
The Smart Switch includes features for quickly expanding
and growing your network. To substantially increase
network throughput speeds, especially useful for
companies whose employees are routinely backing up
their hard drives to a company server or storage platform,
the Smart Switch supports Link Aggregation which allows
multiple high-bandwidth trunks between switches to be
set up. Link Aggregation also provides a level of availability
and redundancy as traffic will continue to flow even if one
of the network links breaks. The Smart Switch’s Spanning
Tree Protocol support (STP) and Storm Control features
help to control planned or inadvertent cable loops when
switches are connected to one another. These loops can
cause broadcast or multicast storms in the network and
severely limit its performance. With these features, you can
confidently build a mesh of switches and quickly expand
your network to support your growing workforce.
The Smart Switch includes numerous QoS features to
ensure that traffic is prioritized properly to deliver the
best possible user experience for real time applications
like voice and video or bandwidth intensive graphic/
video file uploads or downloads. With its IGMP Snooping
feature, the Smart Switch limits IP multicast traffic (real
time presentations, videoconferences, on-line gaming)
to only the ports that have requested it enabling the rest
of the network to operate at peak efficiency. Additional
QoS capabilities like IEEE 802.1p Priority Tagging, DSCP
(Differentiated Services Code Point), and 4 hardware
queues also maintain quality for real-time applications like
voice and video. Network traffic can be optimized with the
switch’s 802.1Q VLAN (Virtual LAN) support which enables
you to quickly segregate network traffic by department
or workgroup. VLANs also provide an additional layer of

Ethernet 1-48 The Switch is equipped with 48
auto-sensing, Ethernet network ports, which
use RJ-45 connectors. The Fast Ethernet ports
support network speeds of 10 Mbps, 100 Mbps,
or 1000 Mbps. They can operate in half- and fullduplex modes. Auto-sensing technology enables
each port to automatically detect the speed of
the device connected to it (10 Mbps, 100 Mbps,
or 1000 Mbps), and adjust its speed and duplex
accordingly.
miniGBIC (1-2) The miniGBIC (gigabit interface
converter) port is a connection point for a
miniGBIC expansion module, so the Switch can
be uplinked via fiber to another switch. The
MiniGBIC port provides a link to a high-speed
network segment or individual workstation at
speeds of up to 1000 Mbps.
To establish a Gigabit Ethernet connection using
a miniGBIC port, you will need to install a MGBT1,
MGBSX1, or MGBLH1 Gigabit expansion module

Pre-Installation Considerations
Fast Ethernet Considerations
If you are using the Switch for Fast Ethernet (100 Mbps)
applications, you must observe the following guidelines:
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.
Positioning the Switch
Before you choose a location for the Switch, observe the
following guidelines:
Hub† Hub 5 meters (16.4 feet)
Switch or Hub† Computer 100 meters (328 feet)
A hub refers to any type of 100 Mbps hub. A 10 Mbps hub connected
†
to another 10 Mbps hub can span up to 100 meters (328 feet).
Business Series Smart Gigabit Ethernet Switch
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
(50 mm).
Do not stack free-standing Switches more than four
•
units high.
Placement Options
There are two ways to physically install the Switch, either
set the Switch on its four rubber feet for desktop placement
or mount the switch in a standard-sized, 19-inch wide, 1Uhigh rack for rack-mount placement.

source.
Keep enough ventilation space for the switch and
•
check the environmental restrictions mentioned in the
Specifications Appendix as you are placing the Switch.
Connect the Switch to network devices according to
•
the Hardware Installation instructions below.
Attaching the Switch’s Rubber Feet
Rack-Mount Placement
To rack-mount the Switch in any standard 19-inch wide,
1U high rack, follow the instructions described below.
Place the Switch on a hard flat surface with the front
1.
panel facing you.
Attach a rack–mount bracket to one side of the Switch
2.
with the supplied screws and secure the bracket
tightly.
Attaching the Brackets
Follow the same steps to attach the other bracket to
3.
the opposite side.
After the brackets are attached to the Switch, use
4.
suitable screws to securely attach the brackets to any
standard 19-inch rack.
When rack-mounting the Switch, please observe the
following guidelines
Elevated Operating Ambient If installed in a closed
•
or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater
than room ambient. Therefore, consideration should
be given to installing the equipment in an environment
compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
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).
