FLEX24-Port Managed Switch


The FLEX managed switch delivers fast Ethernet and PoE++ (50 watts per port) over multiple pairs of UTP cable with six times the reach of traditional switches.

FLEX was designed to make the migration to IP quick, easy and cost effective by leveraging an existing 2 or 4 pair UTP infrastructure. Benefits include:

  • Accelerating your return on investment by reducing infrastructure costs.
  • Collapsing planning and deployment time.
  • Eliminating infrastructure barriers, risks, disruption and costs.
  • Creating a robust IP platform that is easy to configure, deploy and manage.

Unlike other Network Switches, FLEX Delivers:

Speed, Reach and Power

The Flex switch can operate in standard mode (without an adapter) and long reach PoE mode for extended reach. One switch, many options.

Cable Type Data Rate Reach
4 pair CAT5e 100 Mbps 2000ft / 610m
2 pair CAT5e 100 Mbps 1000ft/ 300m
1 pair CAT5e 100 Mbps 950ft / 290m (adapter must be locally powered)

Industry Leading PowerWISE® Technology

Power sharing for redundancy, load balancing, AC/DC options, hot swappable power supply and auto sensing 100-240VAC delivering 500 to 1,000 watts of power.

FLEX is one of the most energy efficient switches on the market consuming less than 20 watts of power to operate.

Managed Switch with Plug-and-Play Option

FLEX can operate in transparent mode functioning as a bridge allowing for plug-and-play deployment or as a fully managed switch with high value features including:

  • Power management by port for easy reset of ports.
  • Port MAC locking for higher security and peace of mind.
  • Simple Network Manager, an intuitive web GUI that makes managing the switch a breeze.
