Patent number: 10998763Abstract: A device may include a power supply module (PSM). The PSM may receive information regarding one or more programmable restrictions associated with a power supply. The PSM may receive a measurement of voltage associated with the power supply. The PSM may determine a current associated with the power supply based on the one or more programmable restrictions, the measurement of voltage, and a first amount of power associated with the power supply. The PSM may cause a load associated with the power supply to be adjusted based on determining the current without removing power for a connection between the power supply and a power source associated with the power supply. The PSM may cause the power supply to provide a second amount of power based on causing the load associated with the power supply to be adjusted.Type: GrantFiled: May 16, 2019Date of Patent: May 4, 2021Assignee: Juniper Networks, Inc.Inventors: Katsuhiro Okamura, Jaspal S.

Patent number: 10277534Abstract: A system may receive, by a switching component of the system, network traffic to be provided to an I/O component of the network device. The system may route, by the switching component, the network traffic to the I/O component based on whether the I/O component is connected to the switching component via the first connections and/or via second connections. The first connections may be connections via a chassis of the system. The second connections may be connections via a connector component that is removable from the switching component. The network traffic may be routed via the first connections and the second connections when the I/O component is connected via the first connections and the second connections. The network traffic may be routed via the first connections and not via the second connections when the I/O component is connected via the first connections and not via the second connections.Type: GrantFiled: June 1, 2016Date of Patent: April 30, 2019Assignee: Juniper Networks, Inc.Inventors: John Kenney, Christopher Otte, Bhavesh Patel, Valery Kugel, Muhammad Sagarwala

Patent number: 9735571Abstract: A system may include a power module that includes a group of power supplies, particular ones of the group of power supplies being operable at a group of voltages ranging from a first voltage to a second voltage. The system may further include a controller coupled to the particular ones of the group of power supplies, the controller being to ramp up an output voltage, associated with the group of power supplies, from the first voltage to the second voltage in a group of discrete steps; where ramping up the output voltage by a particular one of the group of discrete steps is performed while a load is receiving power from the group of power supplies; and where ramping up the output voltage by a particular one of the group of discrete steps prevents over-current protection on the group of power supplies from being activated.Type: GrantFiled: April 30, 2014Date of Patent: August 15, 2017Assignee: Juniper Networks, Inc.Inventors: Muhammad Sagarwala, Thomas Alexander, Jaspal S.

Patent number: 9673567Abstract: The disclosed apparatus may include a lock that has a locking mechanism that secures an electronic module to a telecommunication system. The lock may also have an ejection handle coupled to the locking mechanism such that application of physical force to the ejection handle ejects the electronic module from the telecommunication system by undoing the locking mechanism. The disclosed apparatus may also include a cross-bar coupled to the lock and movable in conjunction with the ejection handle. The cross-bar may facilitate access to a row of power connectors arranged along a surface of the electronic module when the ejection handle is positioned in a first position. Additionally or alternatively, the cross-bar may block access to the row of power connectors arranged along the surface of the electronic module when the ejection handle is positioned in a second position. Various other apparatuses, systems, and methods are also disclosed.Type: GrantFiled: March 12, 2015Date of Patent: June 6, 2017Assignee: Juniper Networks, Inc.Inventors: Michael Braylovskiy, Jaspal S.

Patent number: 9484771Abstract: Techniques are described for determining whether power from a first power source is unavailable to a power supply module. In response to determining that power from the first power source is unavailable, the techniques de-couple the first power source from one or more components of an electronic device connected to an output of the power supply module with one or more de-coupling components of the power supply module that connect an automatic transfer switch (ATS) of the power supply module to an output of the power supply module. Subsequent to de-coupling the first power source from the one or more components of the electronic device, the techniques de-couple a power supply module from the first power source. The techniques couple the power supply module to a second power source for delivering power to the one or more components of the electronic device.Type: GrantFiled: January 10, 2014Date of Patent: November 1, 2016Assignee: Juniper Networks, Inc.Inventors: Michael Braylovskiy, Jaspal Gill, Muhammad Sagarwala
