The NETGEAR ProSafe "Intelligent Edge" Gigabit L2+ Managed Switch GSM5212P consist of 12 ports Gigabit with PoE+ connectivity, and 4 ports dual-speed SFP with fiber connectivity. Intelligent Edge series deliver a secure and flexible access in campus, commercial and enterprise converged environments: Wireless access points, IP telephony and video-surveillance.

PoE Pass-Through
In addition to very low acoustics for deployment in open areas, GSM5212P provides innovative PoE pass-through functionality for challenging environments without outlet such as conference rooms or retail sales floors: GSM5212P can be powered by PoE upstream switches and simultaneously power PoE devices downstream. Up to 22W power can be redistributed locally in Pass-Through mode.

Intelligent Edge
Combining superior resiliency and advanced security, GSM5212P provides comprehensive Layer 2, Lite Layer 3 and Layer 4 switching, including 16K MAC table size, 64 routing interfaces and 16 static routes.

Unified Communications – Voice over IP
The NETGEAR ProSafe "Intelligent Edge" simplifies converged data deployments with state-of-the-art capabilities. CoS Layer 2 prioritization and DiffServ Layer 3 & 4 policies allow for 1Kbps ingress and egress TCP/UDP granularity. LLDP-MED (Media Endpoint Discovery) automatically configures IP phones QoS and VLAN settings.

Unified Communications – Video Streams
IGMP filtering and querier ensure multicast streams are only delivered to interested receivers, preventing flooding even without a dedicated multicast router. When receivers are in different VLANs, Multicast VLAN registration (MVR) uses a dedicated multicast VLAN to forward multicast streams and avoid duplication for clients in different VLANs.
