Filed:

Mar 27, 2008

Appl. No.:

12/056420

Inventors:

Michael Boraas - Elgin MN, US
Aaron Hegrenes - Rochester MN, US
Nathan Karl - Rochester MN, US
David Lund - Byron MN, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

B62B 3/02

US Classification:

280 7911, 16 30

Abstract:

A novel caster assembly with a horizontally orientated arm is attached to a base plate of a rack during a travel state and a stored state. A leveling foot with a flat portion and a non-flat portion is inserted through a slot on the arm and a hole on the base plate such that during the travel state, the horizontal orientated arm is in a fully extended position, and during the stored state, the horizontal orientated arm is in a non- extended position.

US Classification:

36167955, 439701, 206366, 248918, 400685

Abstract:

A cover latch is provided for coupling a blade server cover to a blade server when the cover latch is in a locked state. Embodiments include a locking surface at one end of the cover latch; a user interface at an end of the cover latch opposite from the end with the locking surface; wherein when the cover latch is in the locked state, the locking surface engages a locking surface enclosure of the blade server cover; wherein when the cover latch is in an unlocked state, the user interface is rotated into the blade server and the locking surface is rotated outward from the blade server, wherein when the locking surface is rotated outward from the blade server, the locking surface is disengaged from the locking surface enclosure of the blade server cover; and a rotational limiter hole in the cover latch that surrounds a peg of the blade server, wherein the rotation of the locking surface and the user interface is limited by the rotational limiter.

International Classification:

G06F 1/16

US Classification:

36167933, 361724, 361725

Abstract:

An enclosure assembly and system are provided for implementing cover-mounted, auto-docking for multiple DASD configurations in information technology equipment. A user selected direct access storage device (DASD) configuration is mechanically attached to an enclosure cover. A cover interposer card is mechanically attached to the enclosure cover and electrically connected to each DASD in the user selected DASD configuration. An electrical connector mates with the cover interposer card as the cover is installed through a sliding motion with a chassis and base planar of the enclosure assembly. A flexible cable interconnect attached to the mating electrical connector is connected to the base planar. The enclosure assembly enables high density, high performance modular server architectures without compromising processor performance or planar electrical architecture.

US Classification:

Abstract:

An assembly and associated installation method for a server or other electronic equipment enclosure installable into a rack solves both the issues of a single person installation method, as well as tolerance stack-up problems. A mounting bracket is attached to each end of a sliding rail coupled to the server or other equipment enclosure. The mounting bracket includes pins which are inserted into mounting apertures in the posts of the rack to temporarily retain and hold the sliding rail in the rack. Subsequently, a single user can then insert screws or other mechanical fasteners to securely attach the mounting bracket and sliding rail coupled thereto to the rack. Advantageously, the mounting bracket is fixedly secured to the rack and the sliding rail is permitted to move, translate or pivot relative to the mounting bracket to account for tolerance stack-up issues or other abnormalities in the dimensional fit between the server and rack system. The design of the mounting bracket inhibits appreciable vertical translation of the sliding rail thereby providing for proper clearance for the rack space below.
