## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to and is a divisional of co-owned co-pending U.S. patent application Ser. No. 11/454,210, filed Jun. 16, 2006, which is incorporated herein by reference in its entirety.


BACKGROUND
The present disclosure relates generally to information handling systems, and more particularly to supporting a plurality of cards in an information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Some IHSs include a plurality of cards coupled to an IHS chassis and extending from the IHS chassis adjacent each other and into an IHS housing. Because of the desire to reduce the size of the IHS chassis, the supporting of these cards raises a number of issues.
Reducing the size of the IHS chassis reduces the size of the IHS housing in which the cards are located. As the size of the IHS housing is reduced, the cards must be located closer to each other and to the walls of the IHS chassis that define the IHS housing. During shock and vibration of the IHS chassis, the cards can deflect and come into contact with each other and/or the chassis walls on the IHS chassis that defined the IHS housing, which can result in damage to and/or failure of the cards.
Accordingly, it would be desirable to provide for supporting a plurality of cards in an IHS absent the disadvantages found in the prior methods discussed above.
SUMMARY
According to one embodiment, a method for supporting a card in an information handling system (IHS) chassis, comprising providing a base member, moveably coupling a first securing member to the base member, wherein the first securing member comprises a first card engagement feature located a first height above the base member, wherein the first securing member comprises a first locking member, whereby the first locking member engages the base member such that the first securing member is movable in a first direction but is restricted by the engagement of the first locking member and the base member from moving in a second direction that is opposite the first direction; and a second securing member moveably coupled to the base member, wherein the second securing member comprises a second card engagement feature located a second height above the base member, whereby the second height is different from the first height.

Referring now to FIGS. 2, 3a, 3b, 4a, 4b, 5, 6a, 6b, 6c, 6d, 6e, 6f, and 6g, a method 600 for supporting a card in an IHS is illustrated. The method 600 begins at step 602 where a chassis with a first securing member and a second securing member is provided and proceeds to step 604 where a first card and second card are coupled to the chassis. The IHS chassis 500, described above with reference to FIG. 5, is provided. The first card 516 and the second card 518, shown already coupled to the connectors 506 and 508, respectively, on the base 502 may be coupled to the IHS chassis 500 using methods known in the art to engage the first card 516 with the connector 506 and the plurality of first card supports 504a and to engage the second card 518 with the connector 508 and the plurality of second card supports 504b. 
In an embodiment, the first securing member 300 and the second securing member 400 are provided on the IHS chassis 500 as follows. The first securing member 300 is coupled to the base member 200 by positioning the first track 206 on the base member 200 in the coupling channel 302g defined by the first securing member 300 and the second securing member 400 is coupled to the base member 200 by positioning the second track 208 on the base member 200 in the coupling channel 402g defined by the second securing member 400, providing a card supporting apparatus 602a, as illustrated in FIG. 6b. In an embodiment, the stop surface 214a is operable to prevent the first securing member 300 from decoupling from the first track 206. In an embodiment, the stop surface 214b is operable to prevent the second securing member 400 from decoupling from the second track 208. With the first securing member 300 coupled to the first track 206 on the base member 200, the plurality of teeth 306b on the locking member 306 of the first securing member 300 engage the teeth 206b and 206c on the first track 206 of the base member 200, and the engagement channel 304ca of the first card engagement feature 304c is located a height H1 above the bottom surface 202b of the base member 200, as illustrated in FIG. 6c. With the second securing member 400 coupled to the second track 208 on the base member 200, the plurality of teeth 406b on the locking member 406 of the second securing member 400 engage the teeth 208b and 208c on the second track 208 of the base member 200, and the engagement channel 404ba of the first card engagement feature 404b is located a height H2 above the bottom surface 202b of the base member 200, as illustrated in FIG. 6d. In an embodiment, the height H1 is greater than the height H2. In an embodiment, the heights H1 and H2 may vary depending on the location of the first card 516 and the second card 518 in the IHS chassis 500.
The card supporting apparatus 602a is then coupled to the IHS chassis 500 by first positioning the card supporting apparatus 602a adjacent the IHS chassis 500 such that the bottom surface 202b of the base member 200 is adjacent the securing member support surface 502e, the locating members 210a and 210b are located adjacent the securing member locator 510, and the chassis securing member 212 is located adjacent the securing member coupler 512, as illustrated in FIG. 6e. The card supporting apparatus 602a is then moved in a direction A towards the securing member support surface 502e such that the bottom surface 202b of the base member 200 engages the securing member support surface 502e, the locating members 210a and 210b are located between the guide members 510a, and the securing beam 512b and guide 512a are located in the channel 204 defined by the base member 200, with the securing beam and adjacent the chassis securing member 212, as illustrated in FIG. 6f. The card supporting apparatus 602a is then moved in a direction B such that the locating members 210a and 210b enter the locating apertures 510ba and 510bb, respectively, defined by the locating member 510b, the sides 202e and 202f of the base member 200 engage the guide members 510a, and the beveled securing end 212a on the chassis securing member 212 enters the coupling aperture 512ba defined by the securing beam 512b such that the chassis securing member 212 deflects and allows the securing surface 212b on the chassis securing member 212 to engage the securing surface 512bb on the securing beam 512b, as illustrated in FIG. 6g. While the card coupling apparatus 602a has been illustrated as a separate component that may be removeably coupled to the IHS chassis 500, in an embodiment, the first securing member 300, the second securing member 400, and/or the base member 200 may also be fabricated as an integral part of the IHS chassis 500.
Referring now to FIGS. 6h, 6i, and 6j, the method 600 then proceeds to step 606, where the first card 516 and the second card 518 are supported with the first securing member 300 and the second securing member 400. The second securing member 400 is moved in a direction C such that the distal end 518a of the second card 518 is located in the engagement channel 404ba of the second securing member 400, as illustrated in FIG. 6h. Due to the structure and engagement of the teeth 406b on the locking member 406 of second securing member 400 and the teeth 208b and 208c on the second track 208 of the base member 200, the second securing member 400 may move in the direction C but is restricted from moving in a direction opposite the direction C. The first securing member 300 is then also moved in the direction C such that the distal end 516a of the first card 516 is located in the engagement channel 304ca of the first securing member 300, as illustrated in FIG. 6i. Due to the structure and engagement of the teeth 306b on the locking member 306 of first securing member 300 and the teeth 206b and 206c on the first track 206 of the base member 200, the first securing member 300 may move in the direction C but is restricted from moving in a direction opposite the direction C. In an embodiment, the first securing member 300 and the second securing member 400 can support a variety of different sized cards due to the adjustability of the first securing member 300 and the second securing member 400 provided by the engagement of the teeth 306a, 206b and 206c and the teeth 406c, 208b, and 208c. Thus, a method and apparatus are provided which allow a plurality of cards to be supported in an IHS such that the movement of the cards is restrained during shock and/or vibration of the IHS chassis. In order to release the first card 516 from the first securing member 300, a force D is applied to the handle 306c on the locking member 306 of the first securing member 300, deflecting the beam 306a such that the teeth 306b on the locking member 306 disengage the teeth 206b on the first track 206 and the first securing member 300 may be moved in a direction opposite the direction C. The second card 518 may be released from the second securing member 400 in substantially the same manner.
Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiments may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein.
