System And Method For Multiple Poe Power Supply Management

View page
US Patent:
7908494, Mar 15, 2011
Filed:
Sep 26, 2007
Appl. No.:
11/861861
Inventors:
Asif Hussain - Tustin CA, US
Sesha Thalpasai Panguluri - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G06F 1/00
US Classification:
713300
Abstract:
A system and method for multiple power over Ethernet (PoE) power supply management. Power supply status signals indicative of an operating condition of a plurality of PoE power supplies are provided to a plurality of power sourcing equipment (PSE) controller chips. Pre-configured combination logic within each of the PSE controller chips converts an indicated operational state of the plurality of PoE power supplies into a powering decision for each of the Ethernet ports served by the PSE controller chip within one microsecond.

System And Method For Automatically Discovering Total Transistor Resistance In A Hybrid Power Over Ethernet Architecture

View page
US Patent:
7944221, May 17, 2011
Filed:
Feb 7, 2008
Appl. No.:
12/027605
Inventors:
Wael William Diab - San Francisco CA, US
Hemanth Nekkileru - San Jose CA, US
Sesha Thalpasai Panguluri - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G01R 27/00
G06F 1/26
US Classification:
324713, 324600, 713300
Abstract:
A system and method for automatically discovering total transistor resistance in a hybrid power over Ethernet (PoE) architecture. A critical factor for a PoE system is the total resistance of the power FET. Typical PoE systems consist of a single power FET that may be integrated with the controller or external to the controller. In a hybrid architecture the PoE system consists of both an internal power FET and an external power FET. The external power FET can be used to customize a design to meet a particular application or need. The total resistance in the hybrid architecture can be automatically determined using voltage and current measurements of the internal and external power FETs.

Power Over Ethernet Power Sourcing Equipment Architecture For Variable Maximum Power Delivery

View page
US Patent:
8026635, Sep 27, 2011
Filed:
Apr 5, 2010
Appl. No.:
12/753948
Inventors:
Wael William Diab - San Francisco CA, US
Hemanth Nekkileru - San Jose CA, US
Sesha Thalpasai Panguluri - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H02J 1/10
US Classification:
307 29
Abstract:
A power over Ethernet (PoE) power sourcing equipment (PSE) architecture for variable maximum power delivery. PoE PSE subsystems rely on some control to “turn on” a power field effect transistor (FET), which allows current to be transmitted to a powered device (PD). A hybrid approach is provided where an internal FET can be augmented with an external FET to provide an architecture that can be flexibly applied to applications with various space, cost and cooling limitations. The maximum delivered power can also be boosted with the addition of an external FET to the internal FET.

System And Method For Power Sourcing Equipment Detection Of A Powered Device Power Failure For Power Backup

View page
US Patent:
8028175, Sep 27, 2011
Filed:
Mar 14, 2008
Appl. No.:
12/048281
Inventors:
Wael William Diab - San Francisco CA, US
Sesha Thalpasai Panguluri - Santa Clara CA, US
Hemanth Nekkileru - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G06F 1/00
G06F 11/30
US Classification:
713300, 713310, 713340
Abstract:
A system and method for power sourcing equipment (PSE) detection of a powered device (PD) power failure for power backup. A PSE can power a PD at a low level of power as a backup power source. Upon a failure in the PDs primary power source, the PSE can detect a transient (e. g. , current and/or voltage) on the PD load as a signal that the PD requires additional power. The PSE can then allocate increased power to the port by entering into an active state as compared to a backup state. As the PSE is responsive to the detection of the transient, the PSE need not rely on a real-time communication from the PD.

Powered Device For Power Over Ethernet System With Increased Cable Length

View page
US Patent:
8030795, Oct 4, 2011
Filed:
Jul 6, 2010
Appl. No.:
12/830919
Inventors:
Asif Hussain - Tustin CA, US
Sesha Thalpasai Panguluri - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G06F 1/26
US Classification:
307 2
Abstract:
Increased cable length Power over Ethernet (PoE) systems are provided. Embodiments can be designed for compliance with IEEE 802. 3af, IEEE 802. 3at, or legacy PoE standards. Embodiments include PSE and PD designs enabled for increased length PoE. Embodiments include example modifications of IEEE 802. 3af PSE system rules, including example modifications of PSE port voltage ranges to support IEEE 802. 3af compliant PDs across increased cable lengths. Embodiments include example modifications of IEEE 802. 3af PD system rules, including example modifications of PD port voltage ranges to enable current IEEE compliant PSEs to support increased cable length PoE. Embodiments include PDs having increased voltage process and/or added voltage protection circuitry to support increased length PoE. Modifications of PSE system rules and PD system rules can be performed independently of each others, so that modified PSEs can be made to work with existing PDs, or vice versa.

System And Method For Exchanging Channel, Physical Layer And Data Layer Information And Capabilities

View page
US Patent:
8565111, Oct 22, 2013
Filed:
Mar 7, 2011
Appl. No.:
13/041482
Inventors:
Wael William Diab - San Francisco CA, US
Nicholas Ilyadis - Merrimack NH, US
Sesha Thalpasai Panguluri - Cupertino CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04L 12/26
H04L 12/56
US Classification:
370252
Abstract:
A system and method for exchanging channel, physical layer and data layer information and capabilities. Diagnostic capabilities can vary significantly between physical layer devices, thereby resulting in a disparity of the diagnostic capabilities on the two ends of a network link. An exchange of diagnostic capabilities between physical layer devices enables a comparison of differences in diagnostic capabilities. Such a comparison enables the identification of the appropriate source of diagnostic information.

Appl. No.:
12/348269
Inventors:
Sesha Thalpasai Panguluri - Santa Clara CA, US
Asif Hussain - Tustin CA, US
Martin McNarney - Morgan Hill CA, US
Hemanth Nekkileru - San Jose CA, US
Palathingal Frank - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G06F 1/00
G06F 1/26
G06F 11/30
US Classification:
713300, 713320, 713324, 713340, 718103
Abstract:
A system and method for global power management in a power over Ethernet (PoE) chassis. Power supply status signals indicative of an operating condition of a plurality of power supplies are provided to a plurality of power sourcing equipment (PSE) controller chips in a plurality of blades of a chassis system. Pre-configured combination logic within each of the PSE controller chips converts an indicated operational state of the plurality of power supplies into a powering decision for each of the ports served by the PSE controller chip. Global power management is also effected through the use of scaling factors for the various blades to ensure that the lowest priority powered port (LPPP) in a first blade does not have a lower priority than the highest priority non-powered port (HPNPP) in a second blade.
