Patent number: 7903541Abstract: According to one embodiment, an Ethernet switch includes a plurality of ports operable to receive and transmit Ethernet traffic. The Ethernet switch also includes system monitoring software operable to receive an indication from a user of a plurality of fault conditions for which generation of an alarm is desired. The system monitoring software is also operable to monitor the Ethernet switch for the plurality of fault conditions and generate a signal indicating a particular one of the plurality of fault conditions has occurred. The Ethernet switch further includes at least one relay responsive to the generated signal that is operable to turn on a respective alarm indicating a particular fault condition has occurred.Type: GrantFiled: October 30, 2008Date of Patent: March 8, 2011Assignee: Cisco Technology, Inc.Inventors: Yen Teresa Nguyen, Manrique J. Brenes, Rachel C. Neal, Craig A. Zimmerman

Patent number: 7880622Abstract: 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.Type: GrantFiled: September 10, 2007Date of Patent: February 1, 2011Assignee: Cisco Technology, Inc.Inventors: Yen Teresa Nguyen, Manrique J. Brenes, James E. Collinge

Patent number: 7475299Abstract: A method and system for real-time bit error ratio determination is disclosed. According to one embodiment, a method is provided in which an operational link error rate of a link is determined and then used to estimate a real-time physical link error rate of the link. In another embodiment, the operational link error rate is determined in response to the detection of an operational link error using a cyclic redundancy check.Type: GrantFiled: February 6, 2004Date of Patent: January 6, 2009Assignee: Cisco Technology Inc.Inventors: Manrique J. Brenes, Yen T. Nguyen
