In Computing
In the computer industry, the term crash cart is used, by analogy to its original meaning in medicine, to mean a cart that can be connected to a server that is malfunctioning so badly that remote access to it is impossible, the intention being to "resuscitate" the server to the point where remote administration works again. Crash carts most commonly include a keyboard, mouse, and monitor, because most servers in a modern high-density environment don't have user input/output devices.
The phrase, as applied to computing, was coined independently from its usage in a medical context. The term "crash" has long been used to describe computer systems failures which require or placement of a computer monitor, keyboard and other peripherals on a rolling "cart" leads rather obviously to the resulting phrase.
Crash carts are a method of last resort in data centers which employ various forms of out-of-band management. In those cases it is used for equipment which does not support the requisite out-of-band infrastructure (OOBI) features or in cases where the OOBI devices (concentrators, switches, terminal servers, etc.) or services themselves have failed.
The term "crash cart" can also refer to a bootable removable medium containing an operating system and any relevant software used to recover computer equipment (such as a server or PC) from a state of failure. This is done when such recovery is not possible using the computer's existing operating system and software. Crash carts in this sense are historically tape cartridges ("carts") or more recently, external or removable hard drives.
