Ethernet switches have PoE Plus for higher power devices
Belden MACH104-16TX-PoEP Ethernet switches with Power over Ethernet Plus (PoE Plus) capability (the IEEE 802.3at standard) delivers increased power for Ethernet-enabled devices.
Belden (NYSE:BDC) introduced the MACH104-16TX-PoEP Ethernet switches with Power over Ethernet Plus (PoE Plus) capability in accordance with IEEE 802.3at standards. (The PoE+ standard allows higher power to go through the Ethernet cable, up to 25.5 W.)
As new technologies evolve and a new breed of Ethernet enabled devices, such as IP cameras, VoIP phones, and video conferencing come on the market, the need for increased power and speed over Ethernet networks is of paramount significance.
The MACH104-16TX-PoEP series of hardened Ethernet workgroup switches are managed all-Gigabit switches with sixteen Gigabit PoE/PoE+ ports and four additional Gigabit RJ45/SFP combo ports. A version with two additional 10 Gigabit XFP ports is also available to facilitate high bandwidth backbone requirements. Power options include a choice of single/dual 110/220 V ac inputs or external 48 V dc external inputs for fanless operation (0 degrees C to + 50 degrees C). Each chassis, measures 448 mm x 44 mm x 345 mm, and can be mounted in a 19-in. cabinet.
The switch’s management functionality reportedly facilitates media redundancy systems such as Hiper ring, MRP (IEC ring function) and rapid spanning tree to ensure a high level of network availability. The extensive security mechanisms provided include multi-client authentication via Radius server, access control via IEEE 802.1x or MAB (MAC Authentication Bypass), IP and MAC port security plus SNMP V3 and SSH. True SNMP functionality allows use of centralized management software - such as Industrial HiVision – for commissioning, remote management, diagnostics and troubleshooting.
Each switch apparently comes with an integrated V.24 and USB interface. The V.24 interface is an RJ11 socket for optional (local) serial configuration, while the USB socket can be coupled with an ACA 21 adaptor (sold separately) to store the configuration data, recall it as necessary, and apparently upgrade or downgrade the operating software automatically, bringing potential downtime to an absolute minimum.
