CHAPTER 7. ENTITIES
A separate board for system management
The main system board A memory module (a DIMM, for instance) A device that holds processors, if they are not mounted on the system board. This would generally be a socket. The main power supplies for the system use this. A plug-in card in a system, a PCI card for instance. A front panel display and/or control panel. A rear panel display and/or control panel. A board that power supplies plug in to A board that disk drives plug in to A board that contains expansion slots. A PCI riser board, for instance. Some other board in the system. A separate board that holds one or more processors. A logical grouping for a set of power supplies Used for internal DC-to-DC converters, like one that is on a board. Note that you would not use this for the main power supply in a system, even it it was a DC-to-DC converter. A board for managing and distributing power in the system A rear board in a chassis.
The main chassis in the system. A sub-unit of the main chassis. Some other board that doesn’t fit the given categories. A sub-chassis that holds a set of disk drives. A sub-chassis that holds a set of peripherals. A sub-chassis that holds a set of devices. The differ- ence between a peripheral and a device is not known. A fan or other cooling device. A group of fans or other cooling devices. A cable routing device. A replaceable memory device, like a DIMM. This should not be used for individual memory chips, but for the board that holds the memory chips. The meaning of this is unknown.
The BIOS running on the system. The operating system running on the system. The main interconnect bus in a system.
