Allied Telesis GS950/28PS V2 24-Port Gigabit PoE+ WebSmart Switch with 4 x SFP
PRODUCT DESCRIPTION
Allied Telesis GS950/28PS V2 24-Port Gigabit PoE+ WebSmart Switch - Local Warranty
Gigabit Speed and PoE+ on Every Port
All 24 x 10/100/1000T ports can deliver PoE+ power (IEEE 802.3at, up to 30 W per port) from a 185 W budget, so cameras, phones and access points run from a single cable. Four 100/1000X SFP ports add fibre uplinks.
Simple Web-Based Management
WebSmart management gives you VLANs, QoS, link aggregation, port mirroring and 802.1X security through an intuitive browser interface, without the learning curve of a fully managed switch.
Wire-Speed Non-Blocking Performance
A 56 Gbps switching fabric and 41.66 Mpps forwarding rate keep all 28 ports running at full speed, with 16K MAC addresses and 10K jumbo frame support.
Low Power, Flexible Mounting
A high-efficiency power supply, low-power chipset and IEEE 802.3az Energy Efficient Ethernet help reduce running costs, and the supplied brackets allow rack or wall mounting.
