D-Link 48 x 10/100 L2 PoE Managed Switch + 2x1GRJ + 2x1GRJ/100FX OPTION

48-port Layer2 Managed PoE Switch, with 2 Combo 1000Base-T/SFP Ports and 2 1000Base-T PortsThe DES-3052P is part of D-LinkTs family of premium devices in the entry-level network management category. With Power over Ethernet PoE support, 4 Gigabit uplinks, comprehensive network security, granular bandwidth control and extensive network management, this switch is rich in functions allowing organisations set up secure and effective departmental networks at an affordable cost.High port density & Power over Ethernet PoE supportThe DES-3052P provides 48 Ethernet ports and is equipped with 4 Gigabit uplinks, with the SFP supporting both fibre Gigabit and 100Base-FX fibre connection for specific applications.802.3af PoE is integrated into every switch port. Hence any 802.3af compliant device can be powered by the switch via the standard Ethernet cables, to a maximum of 15.4W per device and 370 W for the switch.Security, resilience & availabilityThe DES-3052P includes many security features including Access Control Lists ACLs, 802.1X Port-Based/MAC-Based Access Control and 802.1X Guest VLAN so that network access is available only to authorised users.To enhance network resilience, the switch supports Spanning Tree protocols, including 802.1D, 802.1w and 802.1s for redundant bridge paths. In addition, a unique feature, D-Link Safeguard Engine, allows administrators to configure thresholds that limit the impact of packet flooding to the switchTs CPU typically caused by virus/worm outbreaks. This increases the switchs reliability and availability.Traffic monitoring/Bandwidth control with high speed linksNetwork administrators can define throughput levels for each port to manage bandwidth. Fine granularity down to 64 Kbps can be achieved. For Quality of Service QoS, the switch supports 802.1p Priority Queues and packet classification based on ToS, DSCP, MAC, IP, VLAN ID and protocol type, to ensure that critical network services like VoIP, ERP, Intranet and video conference
