CAUSE/

CORRECTIVE

ACTION

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.
