DD9500/DD9800 front panel
The four solid state drives (SSDs), the storage processor (SP), and the fans are
accessed from the front of the system. The SP must be pulled out to provide access
to the DIMMs. The fans are accessed without pulling or removing the SP and they are
hot-swappable. The photo shows the interfaces on the front of the system.

On the front panel to the right of SSD #4 (in Slot 3) are 3 LEDs that show high level
system status. The System Power LED glows blue to show the system is powered on.
Note
The system can have power (be plugged in) but the blue LEDs are off if the system is
powered off.
The SP Service LED is normally off, but glows amber whenever the storage processor
(SP) requires service. The Enclosure Service LED is normally off, but glows amber
whenever the SP or other replaceable parts require service. The System Power and
Enclosure Service LEDs are visible through the front bezel.
