Error Indications for a Disconnected/Damaged Connecting Cable
Right slot
When a duplexed Connecting Cable is disconnected or damaged, the location
of the error can be identified with Auxiliary Area flags (in A270 and A271), the
CS1D I/O Control Unit LED indicators, and the CS1D I/O Interface Unit LED
indicators.
In this example, there is an error in the Connecting Cable between Rack 1,
slot 0 and Rack 2, so the corresponding flag in A270 (A27002) is turned ON.
The flag for the same slot in the following Rack (A27004) is also turned ON.
Since the error occurred in a Connecting Cable after Rack 1, the Duplex Com-
munications Cable Status Flags are OFF for the connections between Rack 1
and Rack 2 (A27101) and between Rack 2 and Rack 3 (A27102).
The CS1D I/O Control Unit and CS1D I/O Interface Unit LED indicators all
indicate errors in the side where the break occurred. The CABLE ERR L Indi-
cator is lit red in the Units above the break and the CABLE ERR R Indicator is
lit red in the Units below the break.
