Adapter element for card cage system
An adapter element is provided for interfacing with a card guide of a card cage system to enable ready definition of various card storage configurations within the card cage system. The adapter element is configured to be removably attached to a card guide so that different card storage configurations may be readily defined within a particular card storage level by removing one or more adapter elements from the corresponding card guides and/or positioning one or more adapter elements in corresponding card guides. Additionally, the adapter element is configured to engage the fasteners of a functional module so as to securely retain the functional module in position in the card cage assembly when the adapter element is attached to the card guide.
1. In an electronic equipment enclosure configured to receive a plurality of functional modules, each of which includes a corresponding card, the electronic equipment enclosure including a card storage system comprising at least a middle card guide and two end card guides that collectively define at least one card storage level, an adapter element comprising:
a card guide interface portion configured to releasably engage a card guide; and
a functional module interface portion attached to the card guide interface portion and configured to receive respective portions of first and second functional modules, wherein selective use of the adapter element defines a plurality of card storage configurations.
2. The adapter element as recited in claim 1 , wherein a first card storage configuration of the card storage level is defined when respective adapter elements according to claim 1 are engaged with each of the card guides.
3. The adapter element as recited in claim 1 , wherein a second card storage configuration of the card storage level is defined when respective adapter elements according to claim 1 are engaged only with the end card guides.
4. The adapter element as recited in claim 1 , wherein selective use of the adapter element facilitates definition of a card storage configuration for use with at least two single-wide cards arranged side-by-side.
5. The adapter element as recited in claim 1 , wherein the adapter element is configured to releasably engage the first and second modules.
6. The adapter element as recited in claim 1 , wherein the adapter element is configured to receive at least a portion of an edge of a card.
7. The adapter element as recited in claim 1 , wherein the adapter element farther comprises means for substantially preventing relative motion between the adapter element and a card guide when the adapter element is attached to a card guide.
8. The adapter element as recited in claim 1 , wherein the adapter element is configured so that insertion of a card edge into the middle card guide is substantially prevented when the adapter element is attached to the middle card guide.
9. The adapter element as recited in claim 1 , wherein the adapter element substantially comprises one of die cast metal; and plastic.
10. The adapter element as recited in claim 1 , wherein none of the plurality of card storage configurations require removal of a card guide.
11. The adapter element as recited in claim 1 , wherein the adapter element includes two channels on opposing sides, the channels being configured to receive respective edges of the first and second functional modules.
12. The adapter element as recited in claim 11 , wherein attachement of the adapter element to the middle card guide prevents storage of a double-wide or wider card at an associated card storage level.
13. The adapter element as recited in claim 1 , wherein the adapter element cooperates with a middle card guide located between two end card guides to define on opposing sides of the middle card guide two respective channels that run substantially the length of the middle card guide.
14. The adapter element as recited in claim 1 , wherein when the adapter element is releasably engaged with an end of the middle card guide the adapter element is configured to block a slot in the middle card guide that receives at least a portion of a double-wide card, and wherein when the adapter element is released from the middle card guide the adapter element is configured to expose a slot in the middle card guide such that the slot is able to receive the at least a portion of the double-wide card.
15. The adapter element according to claim 1 , wherein the function module interface portion comprises first and second channels on respective opposing sides of the adapter element, each channel being configured to substantially align with a respective slot on the card guide, each channel being sized and configured to receive a portion of a functional module.
16. The adapter element as recited in claim 15 , further comprising:
an interconnecting web located between the channels, the interconnecting web including a portion that blocks a slot in the card guide thereby reconfiguring the card guide to support the ends of two cards and prevents insertion of a double-wide or larger card.
17. The adapter element as recited in claim 15 , wherein the adapter element is configured to be releasably engaged with an end of the card guide.
18. The adapter element as recited in claim 15 , wherein the adapter element is configured such that removal of the adapter element corresponds with a change in the size of functional modules that the electronic equipment enclosure is configured to receive.
19. The adapter element as recited in claim 1 , wherein selective use of the adapter element enables definition of at least two configurations, at least one configuration for use with a double-wide and at least one configuration for use with two single-wide cards.
