Cisco 48-port 10/100 Stackable Smart Switch with 4 Gigabit Ports & PoE SLM248G4PS Manuale Utente

Growing businesses require cost-effective, networking solutions that can scale with ever-

changing business needs. The Linksys SLM248G4PS 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 48 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.
Network security is a top priority in any size business; unauthorized access to the network and 

mission critical data is a constant concern. The SLM248G4PS 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 SLM248G4PS 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 4 units of the SLM248G4PS (or up to 192 ports when 

combined with SLM224G4S) to be set up in a switch cluster. SLM248G4PS units can coexist in a switch 

cluster with other Linksys Smart Switches that support Resilient Clustering technology—SLM224G4PS, 

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 SLM248G4PS’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 SLM248G4PS 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.
