EtherWAN's EX27000 series provides an industrial-grade fully managed 28-port switching platform combining high performance switching backbone with robust and secure management features required for mission critical and industrial environments where sustained connectivity is crucial.

The EX27000 series is equipped with 24 fast Ethernet ports and 4 gigabit uplink ports with fixed fiber or SFP options. Industrial-grade allows for fan-less operation in high EMI and vibration environments with a temperature range from -10 to 60°C (14 to 140°F).

Users are able to access EX27000 management features such as port security, IGMP snooping, VLANs, GARP protocols, and LACP via web browser, Telnet, SNMP, RMON, TFTP, and RS-232 console interfaces.

EX27000 is also comply with IEC 61850-3 and IEEE 1613 certified for power substations and EN 50121-4 certified for railway applications, it can be mountable on a 1U rack, and is equipped with EtherWAN's Alpha-Ring self-healing technology, providing less than 15ms fault recovery time making it ideal for applications intolerant to interruption.
