24/48-Port 10/100 + 4-Port Gigabit Stackable Smart Switch with 2 Combo SFPs

Chapter 1

Chapter 1: Introduction

Thank you for choosing the Linksys 24/48-Port 10/100 + 4Port Gigabit Stackable Smart Switch with 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 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.

Introduction

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 Stackable Smart Switches includes SNMP, RMON, Telnet, and HTTP Management options, allowing you to flexibly integrate and manage these devices in your network.

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.

NOTE: On the SLM224G4S, MiniGBIC ports are

shared with standard ports. If a miniGBIC port is used, then the shared standard port on the Switch cannot be used. The following table defines the shared port mapping of the SLM224G4S Switch.

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).

24/48-Port 10/100 + 4-Port Gigabit Stackable Smart Switch with 2 Combo SFPs

Make sure that the Switch is accessible and that the

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 Stackable 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)

One switch in the stack is designated the master unit, which handles the management functions for the entire stack. All other switches in the stack function as slave units. One slave unit can be designated as the backup master which automatically becomes the new master unit if the master unit fails.

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:

Connect one end of a Category 5e Ethernet network

1. 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

3. 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

5. 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

7. cable to port G1 on Unit 4.

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

Connect one end of a Category 5e Ethernet network

9. cable to port G1 on Unit 5.

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

10.

Connect one end of a Category 5e Ethernet network

11. cable to port G1 on Unit 6.

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