2. Record the information from the seven-segment display on the base system.
The display flashes a sequence of codes. To find information about the displayed diagnostic codes, refer to
StorNext Q-Series Storage Install Guide.

ATTENTION Potential degraded performance – To prevent degraded performance, do not twist, fold,
pinch, or step on the cables. Many cables have a minimum bending radius. For example, do not bend
fiber-optic cables tighter than a 5-cm (2-in.) radius. Check the specifications for your cables, and do not
bend any cable tighter than the minimum specified radius.
