SITE CONTROLLER HARDWARE
Verify that the Site Controller computer is a VAX
model, or a PDP model that has been upgraded to a VAX
model (see the VAX Site Controller heading in the
Applications Notes section). If you find that the Site
Controller computer is a PDP model, upgrade kits are
available through Ericsson Service Parts. Alternatively, the
PDP model may be replaced with the current 19A149302P9
VAX model.
SITE CONTROLLER SOFTWARE
The Site Controller computer contains a set of 14
Application Software PROMs and a set of two Personality
PROMs. Both sets are located on the PROM card. Access to
the PROM card in the latest VAX version of the Site
Controller computer is through the back using the following
procedure:
1. Turn off the Site Controller computer.
2. Loosen the two fastener screws holding the back
panel to the chassis (see Figure 3).
