The Cisco Catalyst 4948E features 48 ports of wire-speed 10/100/1000BASE-T Ethernet connectivity, plus 4 additional ports that support optional 1000BASE-X Small Form-Factor Pluggable (SFP) optics for flexible uplink configurations. This combination delivers comprehensive connectivity for high-performance server environments while maintaining wire-speed performance across all ports. We offer the WS-C4948E-E model with enhanced multilayer software capabilities.
Yes, the Catalyst 4948E is specifically designed as a rack-optimized, Layer 2-4 multilayer switch for low-density server aggregation in data centers and high-performance computing environments. Its 1 RU form factor, wire-speed low-latency architecture, and proven Catalyst 4500 Series hardware foundation make it ideal for connecting multiple servers and workstations in rack environments. Contact us today to discuss your data center switching requirements.
The Catalyst 4948E delivers exceptional reliability through optional internal AC or DC 1+1 hot-swappable redundant power supplies and a hot-swappable fan tray with redundant fans, ensuring continuous uptime in mission-critical environments. These features allow you to perform maintenance without service interruption. We offer multiple power supply configurations available from us, including 300W AC and DC options.
The Catalyst 4948E provides comprehensive network management through dedicated 10/100 console and management ports, remote in-band SNMP management, and advanced security features including SNMPv3, SSH v1/v2, access control lists (ACLs), and 802.1x port authentication. It also supports industry-standard protocols like Spanning Tree, VLAN support, and IGMP snooping for robust network control. Visit barcodesinc.com for detailed management documentation.
The Catalyst 4948E is built on the proven Catalyst 4500 Series architecture, offering enhanced multilayer software capabilities and improved performance for modern data center environments. Unlike earlier fixed-configuration models, it provides flexible SFP port options for future-proofing your network infrastructure while maintaining the reliability and low-latency performance that Catalyst switches are known for. Contact us today for migration guidance from legacy switches.
The Catalyst 4948E supports comprehensive industry standards including IEEE 802.1q VLAN, 802.1w Rapid Spanning Tree, 802.3ad Link Aggregation, 802.1x authentication, and full duplex on all Ethernet speeds (10/100/1000BASE-T and 1000BASE-X). It also supports advanced features like IGMP snooping, RADIUS authentication, and Cisco Discovery Protocol v2 for seamless integration into enterprise networks.
