Expanding Wired Connectivity for SOHO Networks
NETGEAR 300 Series Gigabit Ethernet Unmanaged Switches provide easy, reliable, and affordable network connectivity for home and small offices. With these unmanaged plug-and-play switches, you can expand your network connections to multiple devices instantly. The GS305P and GS308P with Power-over-Ethernet (PoE) provides power and data from a single Ethernet (CAT-5) cable to devices such as IP cameras, VoIP/Internet-based phones, wireless access points, etc.
Auto-MDI/MDIX eliminates the need for crossover cables
LED indicators for ease of use
Energy-efficient technology for power savings
Fanless design for silent operation
Auto-negotiation for automatic connection at the highest common speed between switch and an end device
Non-blocking switching architecture for maximum throughput at wire speed
802.1p QoS for traffic/frame prioritization
Plug-and-play; no setup required
Durable and rugged metal case
Ideal for small office and home networks
Standards-based technology ensures interoperability with any standards-based devices in the existing network
Power up to 4 PoE-capable devices (GS305P and GS308P)
802.3af Power Over Ethernet (PoE) for IP cameras, VoIP/ Internet-based phones, wireless access points (GS305P and GS308P)
