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.

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

Introduction

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.

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 halfand 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.

Product Overview

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 SLM2048, 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 SLM2048 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.

Business Series Smart Gigabit Ethernet Switch

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:

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

Business Series Smart Gigabit Ethernet Switch

Chapter 3

Installation

For a 1000 Mbps device:

SLM2048 and SLM2024: Connect a Category 5e Ethernet network cable to one of the numbered ports on the Switch.

SLM248G, SLM248P, SLM224G, SLM224P: Connect a Category 5e Ethernet network cable to port G1 or port G2 on the Switch.

For a 10/100 Mbps PoE device:

SLM248P: Connect a Category 5 Ethernet cable to one of ports 1-12 or ports 25-36 on the Switch.

SLM224P: Connect a Category 5 Ethernet 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.

SLM248P and SLM224P: If a 802.3af-compliant PoE device is connected to one of the Switch’s PoE ports, the Switch automatically supplies the required power.

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 one of the Gigabit ports, and 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.
