Chapter 1

Chapter 1: Introduction

Thank you for choosing the Linksys 24/48-Port 10/100
+ 4-Port Gigabit Smart Switch with Resilient Clustering
Technology and PoE.

These switches allow you to expand your network
securely. User control is secured using 802.1x security
using a RADIUS authentication mechanism and can also
be controlled using MAC filtering.

For Wireless or VoIP deployments, the SLM224G4PS and
SLM248G4PS Switches support the IEEE802.3af standard
for Power over Ethernet (PoE), allowing you to attach PoE­enabled devices to your network. These devices need no
additional power cables or nearby power outlets, resulting
in simpler and less expensive installation. PoE support
also allows devices like cameras and Wireless Access Points
to be positioned in optimal locations, such as in ceilings
and walls—even outdoors.

Introduction

Extensive QoS features makes the solution ideal for real­time 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.

through the corresponding port with an attached
device. Blinks while the Switch is actively sending
or receiving data over that port.

G1-G4 (Green/Amber) Blinks green when the

Switch is actively sending or receiving data at
10/100 Mbps over the corresponding port (G1
through G4). Blinks yellow when the Switch is
actively sending or receiving data at 1000 Gbps
over the corresponding port (G1 through G4).

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.)

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 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.

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:

Make sure that the Switch is accessible and that the

Hub† Hub 5 meters (16.4 feet)

to another 10 Mbps hub can span up to 100 meters (328 feet).

•

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.

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 Stack Mode

The SLM224G4PS and SLM248G4PS Switches can operate
in either standalone mode or stack mode. In standalone
mode, the switch operates independently of other
switches. In stack mode, multiple Stackable Switches are
connected together to effectively form a single switch.
The default operating mode is stack mode.

A Switch stack can contain any combination of
SLM224G4PS and SLM248G4PS units, with the following
limits:

SLM224G4PS only: Maximum of 6 units

•

SLM248G4PS only: Maximum of 4 units

•

SLM224G4PS and SLM248G4PS: Maximum of 192

•

10/100 ports (total among all switches)

To uplink the Switch using a 1000 Mbps Ethernet port,
connect one end of a Cat 5e (or better) Ethernet network
cable to a Gigabit port, then connect the other end of the
cable into the peripheral device’s uplink port. MDI/MDIX
will automatically detect the speed and cable type.

To uplink the Switch using the miniGBIC port, connect
a miniGBIC module to a miniGBIC port whose shared
Ethernet port is not being used (a miniGBIC port and its
shared Ethernet port cannot be used at the same time).
The following table shows which Ethernet ports are shared
with the miniGBIC ports.

24/48-Port 10/100 + 4-Port Gigabit Smart Switch with Resilient Clustering Technology and PoE

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.)

The Switches are connected together using a pair of Gigabit
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:

For a stack with less than 6 switches, the steps are similar
except that port G1 of the last switch in the stack must be
connected back to port G2 of the first switch in the stack.

The following is an example of setting up a stacked
configuration using three SLM248G4PS switches.

Connect port G1 on Unit 1 to port G2 on Unit 2.

“Appendix B: About Switch Stacking.”

For more information on stack configuration using the
Console Interface, refer to “Stack Configuration” and
“System Mode” in “Chapter 4: Configuration Using the
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

1.
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).
