E02-022:
BUS FAIL - GSC BUS Lower byte contains
the bus number that
failed, either 0 or 1
(in hex). The upper
byte of the data word
is reserved. No poll response is being received,
via the GSC bus, from a Controller
Board set up to be an end node.
Both the MOM and one other
Controller Board must be set, by
the DIP switches, to be end nodes
in the system. This other
Controller Board should be placed
at the opposite end of the GSC bus
relative to the MOM, preferably in
the slot nearest to the Terminator
Board. No other Controller Boards
should have the end node dip
switch bit set. When this error
occurs, all devices in the CEC/IMC
are commanded to switch to the
alternate GSC bus. If an end node
responds on the new GSC bus, the
error will be cleared. If not, a
switch is made back to the previous
GSC bus. No further switching
will occur until communications
can be established with an end
node. Corrective Action: Ensure
the Controller Board furthest from
the MOM Controller Board on the
primary backplane structure has the
end node DIP switch bit set. If the
error remains, the probable cause is
a physical break in the GSC bus.

MANAGER Control data link failure between
