• Heavy-duty design for Industrial Ethernet and extended temperature
operation: Fiber ports take more power than copper ports, but the ML3000 design
with Thermal Fins provides for this with heavy-duty components. The ambient
temperature dual-rating is 60°C per UL methods, and 85°C per IEC 60068-2-1 and
IEC 60608-2-2 for 16 hours.
• RSTP-2004 for rings and meshes, fastest fault recovery, interoperability: RSTP-
2004 provides reliable fast recovery from a fault in a redundant LAN, which may
include Multilink switches and routers as well as other vendors industry-standard-
RSTP products. Redundant topologies may include rings, dual-rings, and complex
meshes.
• S-Ring and Link Loss Learn for economical high availability using ring topology:
S-Ring, combined with the Link-Loss-Learn feature, provides reliable fast recovery
of a fault in an economical ring topology, combining unmanaged and managed
switches.
