Flexible lever of external module at server

A computer module for insertion within a chassis, the computer module comprising:

• a module frame insertable into the chassis;
• and
• a lever assembly coupled to the module frame, the lever assembly comprising:
• a base lever rotatably coupled to the module frame, the base lever rotatable between an installed position and an opened position;
• a locking tab seated in a depression of the base lever and rotatably coupled to the module frame for engaging a locking surface on the chassis when in a locked position, the locking tab rotatable between the locked position and an unlocked position;
• and
• a flexible element seated in the depression of the base lever and positioned adjacent to an arm of the locking tab to bias the locking tab into the locked position when the base lever is in the installed position, wherein the arm of the locking tab is configured to compress an elastic portion of the flexible element such that the flexible element is configured to bias the locking tab via the arm of the locking tab, and wherein rotation of the base lever to the opened position induces rotation of the locking tab to the unlocked position.

A method, comprising:

• inserting a computer module into a chassis, wherein the computer module comprises a lever assembly for securing the computer module into the chassis;
• securing the computer module in the chassis in an installed position by engaging a locking tab of the lever assembly against a locking surface of the chassis, the locking tab seated in a depression of a base lever of the lever assembly and rotatable coupled to the computer module for engaging the locking surface;
• accommodating deformation of a midplane by compressing a flexible element coupled to the base lever, the flexible element seated in the depression of the base lever and positioned adjacent to the locking tab;
• and
• releasing the computer module, wherein the releasing the computer module comprises rotating the base lever to an opened position to induce rotation of the locking tab to an unlocked position.
