Cisco-Catalyst WS-C3750X-48T-S
The Cisco Catalyst WS-C3750X-48T-S is a 48-port Gigabit Ethernet Layer 3 managed switch designed for enterprise campus, access-layer, distribution, and branch network deployments. It provides 48 × 10/100/1000BASE-T Ethernet ports, modular uplink support, StackWise Plus technology, advanced security and QoS, and Cisco IOS software with the IP Base feature set.
Description
The Cisco Catalyst WS-C3750X-48T-S is part of the Cisco Catalyst 3750-X Series, an enterprise-class stackable switch family designed for high-performance and resilient network access and distribution deployments.
The switch provides 48 Gigabit Ethernet RJ45 ports, supporting 10/100/1000 Mbps connectivity for workstations, servers, printers, IP phones, wireless infrastructure, and other Ethernet-enabled devices. The 48T model does not provide integrated PoE, making it appropriate for installations where connected devices have independent power sources or where external power solutions are used.
The WS-C3750X-48T-S features a modular uplink architecture, allowing compatible network modules to provide additional Gigabit or higher-speed uplink connectivity. This flexibility makes the switch suitable for connecting the access layer to aggregation and core network infrastructure.
The switch supports StackWise Plus, allowing compatible Catalyst 3750-X switches to operate together as a single logical switching system. StackWise Plus provides up to 64 Gbps of stack interconnect bandwidth, enabling scalable deployments while simplifying network management.
The WS-C3750X-48T-S runs Cisco IOS Software and supports enterprise Layer 2 and Layer 3 functionality. Depending on the installed software feature set, capabilities include VLANs, trunking, STP/RSTP/MST, EtherChannel, static routing, RIP, OSPF, EIGRP, IPv4/IPv6 functionality, QoS, multicast, and enterprise security.
Security capabilities include 802.1X authentication, port security, DHCP snooping, Dynamic ARP Inspection, IP Source Guard, ACLs, and Cisco TrustSec-related capabilities, helping organizations control access and protect network resources.
The -S suffix identifies the IP Base software feature set, providing core enterprise switching and Layer 3 functionality.
