Adjustable EMI baffling apparatus for data storage systems
The present invention is directed to an apparatus for reducing and constraining EMI (electronic magnetic radiation) emissions without affecting the internals of data storage system components. A baffle is attached to the exterior of the housing of a data storage system component by baffle mounts. The baffle is operable between a closed position, where the baffle blocks EMI emitted by connectors on the data storage system component, and an open position, where the connectors are not blocked allowing for servicing and cable management. The baffle may comprise an EMI absorbing material and be tuned to meet specific EMI requirements. The baffle mounts offsets the baffle from the data storage system component and the baffle includes a number of holes to allow airflow. The adjustable EMI baffling apparatus does not interfere with other mounted components while the data storage system component is mounted in a cabinet.
1. An apparatus comprising:
a data storage system component;
a baffle mount coupled to the data storage system component; and
a baffle moveably coupled to the baffle mount so as to shield Electromagnetic Interference (EMI) emitted by interconnect components of the data storage system component , the baffle and baffle mount being configured to provide an open position of the baffle wherein the interconnect components are not shielded and a closed position wherein the interconnect components are shielded, further wherein the baffle rotates between the open position and the closed position on a pin coupled to the baffle, wherein while rotating to the open position the pin slides along a pin slot in the baffle mount and a notch pin of the baffle engages a notch in the baffle mount.
2. The apparatus of claim 1 configured to fit within a standard Electronics Industries Alliance (EIA) cabinet.
3. The apparatus of claim 1 , wherein the baffle mount engages a latch notch in the closed position.
4. The apparatus of claim 1 , further comprising an additional baffle mount coupled to the data storage system component and accommodating an additional pin allowing rotation of the baffle.
5. The apparatus of claim 1 , wherein the baffle comprises a plurality of holes.
6. The apparatus of claim 1 , wherein the baffle mount offsets the baffle from the data storage system component to create space for airflow.
7. The apparatus of claim 1 , wherein in rotating between the closed position and the open position, the baffle rotates according to at least one of the following orientations:
side-to-side;
up and down.
8. The apparatus of claim 1 , wherein the baffle comprises EMI absorbing material.
9. An Electromagnetic Interference (EMI) shielding apparatus comprising:
a baffle comprising EMI absorbing material; and
a baffle mount coupled to an exterior housing of a data storage component, the data storage component having a side hosting data connectors, the baffle mount being coupled to the housing at the side to position the baffle to block EMI emitted by the data connectors;
wherein the baffle comprises a pin that fits within a slot of the baffle mount, allowing the baffle to rotate at the pin between an open position and closed position, further wherein in the open position the baffle exposes the data connectors, and in the closed position the baffle blocks the EMI emitted by the data connectors, wherein while rotating to the open position the pin slides along the slot in the baffle mount and a notch pin of the baffle engages a notch in the baffle mount.
10. The apparatus of claim 9 , wherein the data storage component is configured to fit within a standard Electronics Industries Alliance (EIA) cabinet.
11. The apparatus of claim 9 , wherein the baffle mount engages a latch notch in the closed position.
12. The apparatus of claim 9 , further comprising an additional baffle mount coupled to the housing and accommodating an additional pin allowing rotation of the baffle.
13. The apparatus of claim 9 , wherein the baffle mount offsets the baffle from the data storage component to create space for airflow.
14. The apparatus of claim 9 , wherein in rotating between the closed position and the open position, the baffle rotates according to at least one of the following orientations:
side-to-side;
up and down.
15. The apparatus of claim 9 , wherein the baffle comprises a plurality of holes.
16. A method to shield Electromagnetic Interference (EMI) in an electronic system, the method comprising:
coupling a baffle mount to an exterior of a housing of an information handling system component; and
coupling a baffle to the baffle mount so that the baffle mount is rotatable between a first position and a second position, the baffle being coupled to the mount by fitting a pin of the baffle into a slot of the baffle mount, further wherein the first position is a closed position in which the baffle blocks EMI emissions from a transceiver connector of the information handling system component, further wherein the second position is an open position exposing the connector, wherein while rotating to the open position the pin slides along the slot of the baffle mount and a notch pin of the baffle engages a notch in the baffle mount.
17. The method of claim 16 , wherein the transceiver connector includes a fiber optic pluggable connector.
