FLEX8
DATASHEET
Fast Ethernet and PoE
over Multi-Pair UTP
with up to 2,000ft
(610m) Reach
FLEX8 Unmanaged Switch
The plug and play FLEX8 unmanaged switch makes the modernization to IP
devices (IoT) simple, secure and cost-effective. When paired with the FLEX
Adapters, this powerful enterprise-grade switch delivers fast Ethernet and
PoE over Multi-Pair UTP with up to 2,000ft (610m) reach - that’s 6Xs the
reach of standard Ethernet switches.
With the FLEX8, customers are taking full advantage of Modern LAN
principles, protecting existing infrastructure assets, and eliminating any
need to rip and replace the established UTP cabling. The FLEX8 unmanaged
switch optimizes network design with advanced interoperability and easy
integration into the overall LAN creating a secure, robust path for IP
endpoints.
• Accelerate your return on investment by reducing infrastructure costs.
• Simplify your IP modernization, collapsing planning and deployment time.
• Eliminate infrastructure barriers, risks, disruption and costs.
• Create a robust plug-and-play IP platform that is easy to deploy and manage.
• Be environmentally responsible during your IP upgrades.
