Alloy 24 Port POE VoIP Switch with 2 uplink ports


POEFEM24T2SFP 26-Port Managed PoE Fast Ethernet Switch

Categories: , .

Product Description

The POEFEM24T2SFP features 24 PoE compliant ports running at 10/100Mbps and 2 uplink ports in a paired mini-GBIC (SFP) and Copper /10/100/1000Mbps configuration. This switch is designed for high port density PoE applications such as VoIP phone deployment or IP security camera environments.

The Intelligent Layer 2 SNMP management features enable reliable transport of critical VoIP and Security data, even in congested network environments. VoIP requires prioritisation of Voice Calls over general Network Data and Security system requires not only prioritisation, but also port based link security and reporting of link failures to intelligent SNMP applications. These and other intelligent network features are all supported from the POEFEM24T2SFP switch.

The POEFEM24T2SFP supports the IEEE 802.3af PoE standard for Power Injection (PSE). This injects PoE power onto the Cat5 Cable when it detects the presence of a PoE complaint device. When operating with non PoE devices the switch will shut down the power injecting circuitry and as such not cause any damage to your network devices but still allow them to run on the switch as in the case of a normal Ethernet device. The POEFEM24T2SFP uses a injection voltage of about 48VDC on pins 1, 2, 3, 6.

Other Intelligent Network features offer a complete management solution that can enable you to scale your network from a single departmental switch right up to any Enterprise environment. STP and RSTP offers network redundancy features, IGMP snooping offers support for Streaming Video and Multicasing images, Tagged Vlan offers logical security and management of nodes within defined groups. QOS based on port priority queues and TOS bytes ensure effient forwarding of critical network data.

ONETEC also offers a complete range of Fibre SFP / Mini GBIC modules for distances from 220 meters to 100Kms.
