Abstract: A server information handling system is secured by a bezel that couples to an access location, such as an air vent at a front or rear face of a housing. The bezel includes a security structure having a lock and configured to couple directly at the front face or with a bezel extension at the rear face so that the server information handling system can use the same bezel with both a front face or rear face rack mount. The bezel has a lock integrated with the security structure, an air filter that fits over the security structure to filter air flowing into the housing, and a filter brace that captures the air filter by coupling to the security structure over the air filter. The filter brace attaches and detaches at the security structure when the security structure locks a server information handling system housing so that the air filter can be changed while the housing remains secure.

Abstract: Disclosed herein are related to a system and a method of extending a lifetime of a memory cell. In one aspect, a memory controller applies a first pulse having a first amplitude to the memory cell to write input data to the memory cell. In one aspect, the memory controller applies a second pulse having a second amplitude larger than the first amplitude to the memory cell to extend a lifetime of the memory cell. The memory cell may include a resistive memory device or a phase change random access memory device. In one aspect, the memory controller applies the second pulse to the memory cell to repair the memory cell in response to determining that the memory cell has failed. In one aspect, the memory controller periodically applies the second pulse to the memory cell to extend the lifetime of the memory cell before the memory cell fails.
