Front LEDs
This section describes the primary LEDs and controls on the front of the storage
expansion enclosure for all models. The front view shows the following
components:
v
Front Frame - Metal cage frame containing global indicator lights and a link rate
switch.
v
Drives - Up to 16 removable drives, which are numbered 1 through 16 from left
to right. When a drive is installed, the drive and tray slot designation is set
automatically. The hardware addresses are based on the enclosure ID setting on
the ESM and on the drive's physical location in the storage expansion enclosure.
Note:
The drives in your storage expansion enclosure might differ slightly in
appearance from those shown. The variation does not affect the function
of the drives.
