eCOST | Dell, PowerConnect 3548P - switch - 48 ports - managed

The PowerConnect 3548P Power over Ethernet (PoE) switches provide robust security, resilient stacking and enterprise-class management features that are ideal for edge of network applications requiring speed, availability and management.

High-performance, 48-port Fast Ethernet wire-speed solution which is ideal for resilient stacking, cost-effective wiring closet solutions, desktop connectivity and high-speed network backbone traffic aggregation.
Secure switching using edge authentication via 802.1x, private VLANs, Voice VLANs, Protocol VLANs and SNMPv3. Robust security capabilities provided through flow-based IP and MAC ACLs, port-based MAC security, RADIUS and TACACS+ remote authentication, SSL/SSH encryption, and IP-based management access filtering.
Supports open-industry standards, including advanced Quality of Service (L2, L3 aware), Multiple Spanning Trees, SNTP and IP multicast support, Dynamic Link Aggregation (LACP), dynamic VLAN configurations, port mirroring and Rapid Spanning Tree Protocol.

Versatile remote management uses an industry-standard CLI, an embedded Web interface or an SNMP based management application.

Virtual Cable Tester by Marvell for diagnosing copper connectivity and detecting problems and fibre transceiver diagnostics for troubleshooting transceiver problems.
