ABSTRACT:
A method and apparatus which provide field upgradability of an electrical system's air cooling capacity. In particular, air-moving devices are disposed in an external enclosure which is mated with a base unit in such a way as to convert one of the base unit's exhaust ports to an added inlet port. Accordingly, thermal upgradability in the field is easily provided by removing lower capacity interior blowers, by providing and using an access port into the middle of the old air flow path and by attaching an exterior unit having increased air moving capacity.
