  • Publication number: 20200267869
    Abstract: An enclosure for installation in a server rack has front panel access to multiple release mechanisms. The front panel access allows separate and safe dual tasking of both hot and cold swaps. A hot swap mechanism allows a sled to be ejected while retaining a connection to electrical power. A separate cold swap mechanism releases the sled and also disconnects the electrical connection. When the hot swap mechanism is engaged or enabled, one or more mechanical linkages operate to lock out access to the cold swap mechanism. When the cold swap mechanism is engaged or enabled, the mechanical linkages interferes or blocks manual operation of the hot swap mechanism. Both the hot swap mechanism and the cold swap mechanism thus cannot be inadvertently and/or simultaneously performed.
