The director provides a modular design that enables quick removal and
replacement of FRUs. The power module assembly at the rear of the director also
provides a 9-pin, D-type subminiature (DSUB) maintenance port for connection
to a local terminal or remote terminal. Although the port is typically used by
authorized maintenance personnel, operations personnel can use the port to
configure director network addresses.
