If all status indicators are off, the adapter is not receiving power. Refer to
Chapter
2, Installing the Adapter, for instructions on installing the adapter.
Note:
The UL indicator is not viewable when the drive cover is installed
or closed.
Note:
Interbus compliance requires different LED functions than what is
normally displayed on the front of the drive (Port, Mod, Net A, and Net
B Led’s). LED labels are provided with the adapter for application to the
drive cover.
If any other conditions occur, refer to Chapter 7
, Troubleshooting .
