Cisco 24-port 10/100 Stackable Smart Switch with 4 Gigabit Ports & PoE Datasheet

Cost-effective, secure switching with simplified management, security, and PoE for your growing business

Growing businesses require cost-effective, networking solutions that can scale with everchanging business needs. The Linksys SLM224G4PS Smart Switch with Resilient Clustering technology brings a whole new level of intelligence and security to the network infrastructure at a cost-effective price. It offers 24 10/100 Ethernet (copper) ports with four 10/100/1000 Gigabit

Ethernet copper or optional optical (SFP) interfaces for uplinking the switch to the core network.

SLM224G4PS

Network security is a top priority in any size business; unauthorized access to the network and mission critical data is a constant concern. The SLM224G4PS is able to secure the network through

802.1X port authentication and MAC Filtering. 802.1X requires clients to authenticate themselves before they are given access to the network.

The SLM224G4PS switches provide Resilient Clustering technology which enables several switches to be clustered together and managed as a single switch with one Web Management interface and one IP address. This technology allows up to 6 units of the SLM224G4PS (or up to 192 ports when combined with SLM248G4S) to be set up in a switch cluster. SLM224G4PS units can coexist in a switch cluster with other Linksys Smart Switches that support Resilient Clustering technology—SLM248G4PS,

SLM224G4S, and SLM248G4S.

For Wireless or VoIP deployments, the SLM224G4PS supports the IEEE802.3af standard for Power over

Ethernet (PoE). This eliminates the need for additional power cables or for a power outlet to be nearby. It enables PoE-enabled devices such as IP cameras, IP phones, and Wireless Access Points to be positioned in optimal locations like in ceilings and walls—even outdoors—and in locations where there is an accessible power outlet, thereby reducing installation costs and making installations easier.

Businesses are recognizing the benefits of Voice over IP (VoIP) technology and are quickly migrating their voice services to IP-based platforms, requiring their local area networks to support both voice and data applications. The SLM224G4PS’s extensive QoS features make the solution ideal for real-time applications like Voice and Video. The four priority queues together with Weighted Round Robin and Strict Priority scheduling techniques let network administrators quickly prioritize real-time voice and video traffic over data traffic. Individual users or applications can also 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, Multicast, and Unknown Unicast storm control minimizes and contains the effects that these types of storms have 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 network administrators to control network access and traffic flow.

The SLM224G4PS also includes features for network expansion and faster throughput performance. Link aggregation enables network administrators to create multiple high-bandwidth trunks between switches. This provides a level of reliability because the system will continue to operate if one of the links breaks. Spanning Tree

(STP) allows administrators to avoid network loops and to build a mesh of switches to increase the availability of their network.

The simplified user interface provides an intuitive, secure management platform enabling administrators to better utilize the extensive feature set of the switch, resulting in a better optimized, more secure network.
