24/48-Port 10/100 + 4-Port Gigabit Resilient Clustering Smart Switch with 2 Combo SFPs
Chapter 1:
Introduction
Thank you for choosing the Linksys 24/48-Port 10/100
+ 4-Port Gigabit Smart Switch with Resilient Clustering
Technology and 2 Combo SFPs.
These switches allow you to expand your network securely.
Configuration of the switch is secured using SSL for Web
access. User control is secured using 802.1x security using
a RADIUS authentication mechanism and can also be
controlled using MAC filtering.
Extensive QoS features makes the solution ideal for real-
time applications like Voice and Video. The four priority
queues together with the Weighted Round Robin and
Strict Priority scheduling techniques facilitate efficient
co-existence of real-time traffic with data traffic allowing
them each to meet their QoS needs. Individual users or
applications can be prioritized above others using various
Class of Service options—by port, Layer 2 priority (802.1p),
and Layer 3 priority (TOS or DSCP). Intelligent Broadcast
and Multicast storm control minimize and contain the
effects of these types of traffic 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 you to control network access and traffic flow.
There are features that allow you to expand and grow your
network of switches. Link aggregation allows multiple
high-bandwidth trunks between switches to be set up.
This also provides a level of reliability in that the system
continues to operate if one of the links breaks. Spanning
Tree (STP) and Fast Link allow you to build a mesh of
switches increasing the availibility of the system.
The rich management functionality of the Smart Switches
with Resilient Clustering Technology includes SNMP,
RMON, Telnet, and HTTP Management options, allowing
you to flexibly integrate and manage these devices in your
network.
NOTE: Throughout this User Guide, the term
reset refers to cycling the power to the Switch;
that is, powering the Switch off, then on again.

System (Green/Amber) Lights up green to
indicate that the Switch is powered on.
Lights up amber while the Switch is performing a
system self-test. Blinks amber if the self-test fails.
LINK/ACT (1-24) (Green) Lights up to indicate
a functional 10/100 Mbps network link through
the corresponding port (1 through 24) with
an attached device. Blinks while the Switch is
actively sending or receiving data over that port.
Stack (G1-G4) (Amber) Lights up to indicate
that the corresponding port (G1 through G4) is
linked to another switch. (Two of these LEDs will
be lit if switch stacking is properly configured.)
LINK/ACT (G1-G4) (Green) Blinks when the
Switch is actively sending or receiving data over
the corresponding port (G1 through G4).
1000M (G1-G4) (Yellow) Lights up to indicate a
functional1 Gbpsconnectiononthecorresponding
port (G1 through G4) with an attached device.
Ethernet 1-24 The Switch is equipped with 24
auto-sensing, Ethernet network ports, which
use RJ-45 connectors. The Fast Ethernet ports
support network speeds of 10 Mbps or 100 Mbps.
They 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.
G1-G4 The Switch is equipped with 4 auto-
sensing Gigabit Ethernet network ports, which
use RJ-45 connectors. The Gigabit Ethernet ports
support network speeds of 10 Mbps, 100 Mbps, or
1000 Mbps.They 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, 100 Mbps, or 1000 Mbps),

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 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:
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
settheSwitch onitsfour rubberfeetfordesktopplacement
or mount the switch in a standard-sized, 486,2-mm wide,
1U-high rack for rack-mount placement.

Desktop Placement
Attach the rubber feet to the recessed areas on the
bottom of the Switch.
Place the Switch on a desktop near an AC power 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
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).

Configuring Stacking Mode
The SLM224G4S and SLM248G4S Switches can operate in
either standalone mode or stacking mode. In standalone
mode, the switch operates independently of other
switches. In stacking mode, multiple Resilient Clustering
Smart Switches are connected together to effectively form
a single switch. The default operating mode is stacking
mode.
A Switch stack can contain any combination of SLM224G4S
and SLM248G4S units, with the following limits:
SLM224G4S only: Maximum of 6 units
SLM248G4S only: Maximum of 4 units
SLM224G4S and SLM248G4S: Maximum of 192 10/100
ports (total among all switches)
Each switch in a stack is assigned a unique unit number.
These numbers indicate the switch’s status in the stack:
Unit 1:The switch is the Master unit.The master handles
the management functions for the entire stack.
Unit 2:The switch is the Backup Master unit.The backup
master automatically becomes the new master if the
master fails.
Unit 3, 4, 5, 6: The switch is a Slave unit. (Depending on
the switch models used, 5 and 6 may not be valid.)
TheSwitchesareconnectedtogetherusingapairofGigabit
ports on each Switch: G1 and G2, G3 and G4, or miniGBIC1
and miniGBIC2. Linksys recommends using Gigabit ports
G1 and G2 (the default stacking ports). Connections are
made using Category 5e Ethernet network cables.
To set up a stack with six switches, follow these steps:
Connect one end of a Category 5e Ethernet network
cable to port G1 on Unit 1.
Connect the cable’s other end to port G2 on Unit 2.
Connect one end of a Category 5e Ethernet network
cable to port G1 on Unit 2.
Connect the cable’s other end to port G2 on Unit 3.
Connect one end of a Category 5e Ethernet network
cable to port G1 on Unit 3.
Connect the cable’s other end to port G2 on Unit 4.
Connect one end of a Category 5e Ethernet network
cable to port G1 on Unit 4.
Connect the cable’s other end to port G2 on Unit 5.
Connect one end of a Category 5e Ethernet network
cable to port G1 on Unit 5.

Console Interface”.
For more information on stack configuration using the
Web-based Utility, refer to “Setup > Stack Management”
in“Chapter 5: Configuration Using the Web-based Utility”.
Reassigning a Slave Unit as the Master Unit
You can reassign a slave unit so that it becomes the master
unit. To do this, you swap their unit numbers. For example,
to make slave unit 5 be the master, you change the master’s
unit number from 1 to 5 and the slave’s unit number from
5 to 1. To change the unit numbers, you can use either the
Web-based utility or the console interface.
The following describes the procedure for changing a
slave unit into the master unit. In this example, unit 5 is
made the master unit.
Swap the unit numbers. That is, change the unit
number of the current master from 1 to 5, and change
the unit number of slave unit 5 from 5 to 1. (The order
in which these are performed is not significant.)
Power off the new unit 5 (the former master unit).
Power off the new master unit 1 (the former slave unit
5) briefly, then power it on again.
Power up the new unit 5.
NOTE: If unit 2 (the backup master) is made the
master unit, steps 2 through 4 can be skipped.
Replacing a Stacked Switch
To replace one switch in a stack with another switch
without having to reboot or power down the stack:
Run the Web-based utility.
Go to the Setup > Stack Configuration screen.
Make sure that the Stacking Ports After Reset setting
matches the type of stacking ports (Copper Ports or
Combo Ports) that are used to connect the switches.
Verify that the Unit No. After Reset settings specify the
correct unit number for the switch being replaced.
Click Save Settings to save the stack settings.
Disconnect the switch being replaced, then connect
the new switch using the same stacking ports (copper
or combo) as before.
The stack should continue to operate as before.
