3–9Hub Manager
Self-Test Procedure
As each Hub Manager self-test is executed, its test ID is written to the LCD. In the
event of a failure, the word ”Failed” appears on the display, and testing stops.
For example, if the Diagnostic Code CRC fails, then the following error message
appears on the LCD display:
DEChub 900 V1.1.6
0102 : Failed
The self-test procedure completes in about 15 seconds.
If a self-test error occurs and is displayed on the Hub Status Display, you should
record the failure code number and the version number. Once the error information
is recorded, either contact your Digital service representative, or refer to the DEChub
900 MultiSwitch Hub Manager Installation for removal and replacement procedures.
