System 9000TS
67
When more than one rack is supplied within a 9000TS System a ribbon cable is used
to connect all system bus lines between racks using the ribbon OUT of Rack 1 to
connect to the ribbon IN of Rack 2. Switches are also provided on the inside face of
each of the rack motherboard to allow local communication to be passed between the
last card of Rack 1 and the first card of Rack 2 depending on the card type. Example:-
If the last slot in the upper rack is a P925TS-I Input Card and the first card in the
adjacent rack is a P925TS-O Output Card then the local communication switches must
be set to ON in both chassis as shown in the following diagrams
.
