Updating system software
The CDC seven’s operating system undergoes a programme of continuous
development. The console may be updated by loading new versions of software
as they become available. This can be done automatically by connecting the
console to the Internet (via a hard-wired connection as opposed to a wi-fi link) at
boot-up; if a new software version is available, an alert will be presented on the
main screen.
See the Software Manual for full details.
System expansion
Adding a second Stagebox
This is a simple and transparent procedure. Observe the appropriate MegaCOMMS
network wiring method to be followed – see page 28 for details.
Each stagebox must have a unique address; this is set by the hex switch on the
rear panel. On a second stagebox, this switch should be set to ‘3’. Note that the
first stagebox’s hex switch should be set to ‘2’.
Adding Redundant Power Supplies
A second surface PSU may be added to provide redundancy. The surface is fitted
with two rear panel PSU connectors; the second PSU is simply connected to the
second socket.
A CDC I/O 6448 remote stagebox may also have second PSU added for
redundancy purposes. The stagebox has an internal PSU; a second PSU is
connected to the rear panel multi-way connector. Note that the PSU used in this
case is the same PSU as used to power the control surface.
