Abstract

Disclosed herein is a modular enclosure apparatus for personal computers and/or work stations having a plurality of removable and replaceable modules. These modules include a cooling module for cooling the enclosure; a memory storage device module having a plurality of mating slides and carriers for routine installation and removal of each memory storage device; and a power supply module for providing power to the enclosure. In a RAID embodiment, the modular enclosure apparatus includes a RAID controller module which is similarly removable and replaceable. Each of the modules may include a circuit interrupt assembly for disabling individual modules (by cutting off power to the desired module) and allowing that module or parts contained therein to be removed while the power is disabled only to the module desired and the remaining modules continue to be enabled.

Claims

means for mounting a plurality of electrical devices within the frame, the means for mounting electrical devices includes a tab;

a memory storage device module removably connected to the frame, the memory storage device module including means for removably connecting at least one memory storage device, the means for removeably connecting at least one memory storage device includes a locking recess, the locking recess connects with the tab;

a power supply module removably connected to the frame, the power supply module including power supply means for supplying power to the enclosure;

first interconnect means for connecting the enclosure to the computer bus;

second interconnect means for connecting the memory storage device module to the first interconnect means; and

third interconnect means for connecting the power supply module to the cooling module and the memory storage device module,

whereby, each of the modules is removably connected, allowing any of the modules to be removed and replaced.

2. A modular enclosure as set forth in claim 1, wherein the frame is slidably connected to the housing.

3. A modular enclosure as set forth in claim 1, wherein the cooling module includes cooling means for cooling the enclosure and cooling circuit means connected to the third interconnect means for supplying power to the cooling module, the cooling circuit means including temperature sensing means for sensing the temperature of the enclosure and circuit interrupt means for interrupting the circuit, whereby the cooling means may be shut off before it is removed from the enclosure.

4. A modular enclosure as set forth in claim 3, wherein the cooling module is removably connected to the back of housing and wherein the back of the housing comprises a removable back assembly enabling the cooling module to be accessed without having to remove any other element of the modular enclosure.

5. A modular enclosure as set forth in claim 4, wherein the cooling means includes at least two fans and wherein each of the fans is capable of cooling the entire enclosure by itself and wherein each of the fans can be removed while one or more of the other fans are operating.

6. A modular enclosure as set forth in claim 5, wherein each of the fans are variable speed fans and wherein, as appropriate, the temperature sensing means directs the speed of the fans in response to the temperature of the enclosure, whereby if one of the fans fails and the temperature in the enclosure rises, the other of the fans are directed to speed up to properly cool the enclosure.

7. A modular enclosure as set forth in claim 5, wherein each of the fans has a diameter of no more than 120 mm.

8. A modular enclosure as set forth in claim 5, wherein each of the fans has a diameter of approximately 92 mm.

9. A modular enclosure as set forth in claim 1, wherein the frame comprises part of the cooling module, the frame being vented to allow air to flow therethrough.

10. A modular enclosure as set forth in claim 1, wherein the memory storage device module includes at least one memory storage device slide semi-permanently mounted in the frame mounting means and at least one carrier adapted for removable connection with the slide, the carrier adapted for connection with a memory storage device.

11. Modular enclosure as set forth in claim 10, wherein the slide includes electrical interrupt means for allowing each of the carriers to be removed from the housing while other memory storage devices present in the enclosure continue operation, defining a hot swappable memory storage device means.

12. A modular enclosure as set forth in claim 1, wherein the memory storage device module includes at least two memory storage device slides semi-permanently mounted in the frame mounting means and at least two carriers adapted for removable connection with the respective slides, the carrier adapted for connection with a memory storage device.

13. A modular enclosure as set forth in claim 10, wherein the carrier including configuration identification means for establishing a compatible connection between the memory storage device and the computer bus.

14. A enclosure as set forth in claim 1, wherein the power supply means includes two or more power supplies.

15. A enclosure as set forth in claim 14, wherein the power supply means load sharing circuit means for sharing the power load among the power supplies.

16. A modular enclosure as set forth in claim 15, wherein each of the power supplies includes circuit interrupt means for allowing each of the power supplies to be removed from the housing while other power supplies present in the enclosure continue operation, defining a hot swappable power supply means.
