Abstract: A server management switch discovers and identifies its switch ports that are connected to communication ports of baseband management controllers (BMC's) of server computers. The server management switch isolates the identified BMC-connected switch ports such that network traffic on a BMC-connected switch port is restricted to a switch port that has a connection, either directly by a link or over a server management network, to a server management computer. Network traffic on BMC-connected switch ports are monitored and controlled in various ways to further protect the BMC's from security attacks.

Abstract: A target image of a target circuit board and a gold image of a gold circuit board are taken by an image acquisition system. Fiducial points are located on the target image and on the gold image. Perspective transformation is performed on the target image using the fiducial points on the target image for reference and on the gold image using the fiducial points on the gold image for reference. After perspective transformation, an anomalous section of the target image is identified by identifying pixels that have different intensities between the target image and the gold image, the anomalous section being indicative of an unauthorized modification to the target circuit board.

Abstract: Various embodiments set forth a method for automatically configuring a multi-chassis link aggregation group (MLAG), including receiving first system information associated with the MLAG, receiving a first discovery packet via a first uplink port associated with a first switch that is included in the MLAG, where the first discovery packet includes second system information associated with the MLAG, determining whether the first system information matches the second system information, where if the first system information matches the second system information, then concluding that the first uplink port is included in an inter peer link connecting the first switch to a second switch that also is included in the MLAG, and if the first system information does not match the second system information, then concluding that the first uplink port is not included in the inter peer link. Advantageously, the method avoids requiring a user to enter hundreds of commands manually.

The set of bars is configured to restrict movement of a load into a space between the set of bearings and lower than the height of the one of more bars, and the height of the one or more bars is lower than the height of the first set of bearings and higher than the rigid plate. At least one advantage in this approach is that an equipment rack can be transported without the use of casters that are permanently attached to the equipment rack.
