Abstract

A cable management arm assembly for a computer server that includes a break-away link that allows the arm assembly to be pivoted away from the back panel of the computer server while the server is attached to a computer rack. The cable management arm further includes an inner arm section, an inner arm slide racket, an outer arm section and an outer arm slide bracket. The inner arm section is pivotably mounted to the inner arm slide bracket at one end, and is pivotably mounted to the break-away link at an opposite end. Likewise, the outer arm section is pivotably mounted to the outer arm slide bracket at one end, and is pivotably mounted to the break-away link at an opposite end. When the computer server is retracted into the rack, the sections pivot and rotate in such a manner that the inner arm section and the outer arm section are in contact with each other and are parallel, where the break-away link forms an extension of the outer arm section. The break-away link allows the folded arm assembly to pivot away from the back panel of the server when the server is in the retracted position.
