Abstract
The present invention provides a device for controlling the time period required to remove a server from a slot. The time period is sufficient for data to be saved from the server prior to power being shut off to the server and its removal from the slot. The device has an arm with a proximal end and a distal end. The arm is mounted for rotation about a first axis from a closed position to an open position. A mechanism applies a motive force to the arm to bias the arm to the open position.
Claims20
A device for controlling the time period required to remove a server from a slot comprising:
- an arm having a proximal end and a distal end and mounted for rotation about a first axis from a closed position to an open position;
- a tensioning mechanism for applying a motive force to the arm to bias the arm to the open position;
- and
- a latch moveable from a latched position to an unlatched position, when in the latched position a portion of the latch engages a portion of the arm and resists rotation of the arm, and when the latch is in the unlatched position the latch is not engaged to the arm to allow rotation of the arm about the first axis.

- and
- a mechanism for initiating movement of the arm from the closed position to the open position.

- and
- a power circuit for providing electrical power to the server, when the arm is in the closed position the power circuit is closed and electrical power is provided to the server,
- and when the arm is an open position the power circuit is open and no electrical power is provided to the server.
