ABSTRACT:
According to one embodiment of the invention a rugged Ethernet switch includes a housing and a passive cooling system associated with the housing and being devoid of fans as operable to cool the Ethernet switch. Ethernet switch also includes software operable to perform at least one of the functions selected from the group consisting of multiple spanning, rapid spanning, cluster management and IGMP snooping and querying. According to another embodiment, a rugged Ethernet switch includes a housing having a plurality of perforations formed therein for cooling the Ethernet switch. The switch also includes a passive cooling system be devoid of fans and that is operable to cool the Ethernet switch. A temperature sensor is operable to measure a temperature of the Ethernet switch is included as is an alarm software responsive to the temperature sensor and operable to initiate an alarm when a measured temperature of the Ethernet switch exceeds a particular limit.
