Abstract: A computer determines a characteristic corresponding to each of a first power source and a second power source. The first and second power sources are connected to one or more power distribution units and are configured to provide power in a datacenter. The characteristic includes at least one of a current, a resistance, a voltage, a frequency, a phase, and a magnetic field. The computer generates a comparison of the characteristic corresponding to the first power source and the second power source, to a threshold value of the characteristic. The computer determines if the comparison violates the threshold value of the characteristic. In response to determining the comparison does not violate the threshold value of the characteristic, the computer determines that the first power source and the second power source are connected to a given power distribution unit included in the one or more power distribution units.

Abstract: A method, system, and/or computer program product allocates network addresses to network devices. A network address providing server designates a particular network address as a designated network address for use with a specific non-network device, where the specific non-network device has a Unique Device Capability Identifier (UDCI), and where the non-network device is not connected to a network. The designated network address is stored in a lookup table containing the UDCI, such that the lookup table associates the designated network address with the UDCI. In response to a request from a network device for a network address including the UDCI, the network address providing server retrieves the designated network address from the lookup table based on the UDCI found in the request for a network address. The designated network address is then sent to the network device for use as a network address of the network device.

Abstract: A heat sink includes a heat sink base having a central area for contacting a heat-generating component and a perimeter area extending beyond the central area, wherein the perimeter area of the heat sink base includes air pathways through the heat sink base and the central area does not. The heat sink further includes heat sink fins extending from the heat sink base across the central area and the perimeter area. Airflow across the heat sink removes heat from the heat-generating component, such as a processor. The central area may be secured in contact with a surface of a processor operably secured to a circuit board. The heat sink is particularly beneficial in circuit board configurations having a component immediately upstream or downstream of the processor.

Abstract: A method includes sensing ambient conditions in a datacenter containing a server, and determining whether the ambient conditions exceed predetermined threshold conditions representing risk of electrostatic discharge. A lid to the server is locked in a closed position in response to the ambient conditions exceeding the predetermined threshold conditions. However, the lid to the server is unlocked in response to a grounding strap being connected to the server. Optionally, the grounding strap may be identified and the server lid will only unlock if the identified grounding strap is associated with authorization to unlock the server lid.

Abstract: A method, computer system, and/or computer program product controls access to a wireless local area network (WLAN) access point in a retail establishment. A predetermined retail activity threshold is established for a retail establishment, where the retail establishment has a patron service area with a WLAN access point, and where a determination has been made that exceeding the predetermined retail activity threshold without increasing patron traffic out of the retail establishment will cause an excessive wait time for occupying the patron service area. In response to determining that the predetermined retail activity threshold is being exceeded, a secondary criterion is examined in order to determine if the mobile device should be disconnected from the WLAN access point, in order to motivate a user of the mobile device to leave the patron service area. If so, then the mobile device is disconnected from the WLAN access point.

Abstract: A method and apparatus for securing electronic components in an electronics system enclosure are disclosed. An apparatus can include an electronics system enclosure having a compartment adapted to receive a removable electronic component. The apparatus also includes a cam having a portion extending into the compartment sufficient to hinder insertion of the removable electronic component in a default orientation. The portion of the cam includes first and second surfaces. The portion of the cam is configured to deflect sufficient to permit insertion of the removable electronic component into the compartment in response to a normal force. The deflection causes the cam to deflect to a modified orientation. The cam portion returns to the default orientation in the absence of the normal force. The second surface of the portion is configured and arranged to engage a cam lever that is rotatably mounted to the removable electronic component.
