Introduction

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.

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.

Blinks green while the Switch is actively sending or receiving data over that port.

LINK/ACT (13-24, 37-48)  (Green) Lights up to indicate a functional 10/100 Mbps network link 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 halfand 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.

Product Overview

G1-G4  The Switch is equipped with 4 autosensing 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 halfand 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), 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 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.

Stack ID  Displays the Switch’s unit ID number if the Switch is in stack mode.

Stack Master  (Amber) Lights up if the switch is the stack Master during stack mode.

NOTE:  On the SLM248G4PS, MiniGBIC ports are shared with Gigabit Ethernet ports. If a miniGBIC port is used, then the shared Gigabit Ethernet port on the Switch cannot be used. The following table defines the shared port mapping of the SLM248G4PS Switch.

Installation

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 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.

Chapter 3

Installation

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).

To rack-mount the Switch in any standard 19-inch wide, 1U-high rack, follow the instructions described below.

1.Place the Switch on a hard flat surface with the front panel facing you.

2.Attach a rack–mount bracket to one side of the Switch with the supplied screws and secure the bracket tightly.

Attaching the Brackets

3.Follow the same steps to attach the other bracket to the opposite side.

4.After the brackets are attached to the Switch, use suitable screws to securely attach the brackets to any standard 19-inch rack.

Mounting in Rack

5.Connect the Switch to network devices according to the Hardware Installation instructions below.

Hardware Installation

To connect network devices to the Switch, follow these instructions:

1.Make sure all the devices you will connect to the Switch are powered off.

2.For a 10/100 Mbps device:

Connect a Category 5 Ethernet network cable to one of the numbered ports on the Switch.

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

Chapter 3

Installation

For a 1000 Mbps device:

Connect a Category 5e Ethernet network cable to port G1, G2, G3, or G4 on the Switch.

For a 10/100 Mbps PoE device:

SLM248G4PS: Connect a Category 5e Ethernet network cable to one of ports 1-12 or ports 25-36 on the Switch.

SLM224G4PS: Connect a Category 5e Ethernet network cable to one of ports 1-6 or ports 13-18 on the Switch.

3.Connect the other end of the network cable to a PC or other network device.

4.Repeat steps 2 and 3 to connect additional devices.

If a 802.3af-compliant PoE device is connected to one of the Switch’s PoE ports, the Switch will automatically supply the required power to the device.

5.If you are using a miniGBIC port, then connect a miniGBIC module to a miniGBIC port. For more detailed instructions, refer to “Uplinking the Switch“.

6.Connect the supplied power cord to the Switch’s power port, and plug the other end into an electrical outlet. When connecting power, always use a surge protector.

IMPORTANT: Make sure you use the power cord that is supplied with the Switch. Use of a different power cord could damage the Switch.

7.Power on the devices connected to the Switch. Each active port’s corresponding LED will light up on the Switch.

Uplinking the Switch

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.

To establish a Gigabit Ethernet connection using a miniGBIC port, you will need to install a MGBT1, MGBSX1, 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.

The hardware installation is complete. Proceed to “Chapter 5: Configuration Using the Web-based Utility”, for directions on how to set up the Switch.

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)

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:

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

Chapter 3

Installation

1.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 1.

2.Connect the cable’s other end to port G2 on Unit 2.

3.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 2.

4.Connect the cable’s other end to port G2 on Unit 3.

5.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 3.

6.Connect the cable’s other end to port G2 on Unit 4.

7.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 4.

8.Connect the cable’s other end to port G2 on Unit 5.

9.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 5.

10.Connect the cable’s other end to port G2 on Unit 6.

11.Connect one end of a Category 5e Ethernet network cable to port G1 on Unit 6.

12.Connect the cable’s other end to port G2 on Unit 1.

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.

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

Connect Unit 1 to Unit 2

2. Connect port G1 on Unit 2 to port G2 on Unit 3.

Connect Unit 2 to Unit 3

3. Connect port G1 on Unit 3 to port G2 on Unit 1.

Connect Unit 3 to Unit 1

For detailed information on switch stacking, refer to “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.

1.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.)

2.Power off the new unit 5 (the former master unit).
