A processor-based device having a plurality of memory cartridges secured within a chassis by a lever system. The processor-based device comprises an indication system to indicate memory system operating conditions. Each memory cartridge has a protective assembly to protect memory elements within the memory cartridge when the memory cartridge is removed from the processor-based device. The processor-based device is operable such that at least one memory cartridge may be removed from the processor-based device without affecting operation of the processor-based device.

Removable memory cartridge system for use with a server or other processor-based device

The control logic for a hot-pluggable memory cartridge for use in a redundant memory system. To implement a hot-pluggable memory cartridge in a redundant memory system, control logic to control the sequence of events for powering-up and powering-down a memory cartridge is provided.

Hot replace power control sequence logic

A method of adding memory capacity to a computer system. The computer system comprises a redundant memory system including a plurality of memory cartridges. By powering-down a memory cartridge, adding an additional memory module to the memory cartridge, and powering-up the memory cartridge for each memory cartridge in the system, the system can transition from a redundant mode of operation to a non-redundant mode of operation for each power-down, thus allowing the computer system to remain functional during the addition of the memory module. Alternatively, memory cartridges with higher memory capacity than those currently present in the computer system can be used to replace existing memory cartridges in the computer system, using the same techniques.

Hot-upgrade/hot-add memory

A method of replacing a memory module in a computer system. Specifically, a method for replacing a memory module in a segment of a redundant memory system, without powering-down the memory system.
