The '''BA11-P card cage''' from [[Digital Equipment Corporation|DEC]] was used in [[PDP-11/60]] to hold the [[Central Processing Unit|CPU]], [[main memory]] and [[device controller]]s.

It held [[DEC card form factor|hex]] [[system unit]] [[backplane]]s, and could contain up to roughly seven standard size (4-slot) system units (the documentation formally specifies six), although the backplane used to hold the CPU was a 14-slot (for the -11/60) unit.

It was one of the [[BA11 mounting boxes]]. It was mounted in an [[H9500]] double-width low-boy corporate cabinet produced by DEC. The backplanes were mounted vertically, facing forward (like those in the later [[VAX-11/780]].

The BA11-P used one (optionally two) [[H742 Power Supply|H7420 Power Supplies]], which were separate units, permanently mounted directly in the H9500, below and behind the BA11-P; a [[power harness]] connected to the two. The [[power supply]] contained up to five [[DEC standard modular regulators]]; the harness ended in a power distribution panel containing standard [[DEC power distribution connectors]].
