v If the Drive fault LED stays on or the Drive activity LED stays off, the newE-DDM might be faulty or might be an uncertified drive. See the DS4000Storage Manager software for problem determination. In the case of anuncertified drive, verify that the drive options or drive FRU part number iscorrect...

Attention: All devices on the loop must have the same data transfer rate, which means that you must set the link rate on the storage expansion enclosure to thesame rate as the storage subsystem to which it is connected. Information aboutsupported DS4000 storage subsystems can be obtained from the ce...

If both Link Rate indicator LEDs are on, the data transfer rate is set for 4Gbps. If one Link Rate indicator light is on, the data transfer rate is set for 2Gbps. 3.
