Front panel

After you unlock and remove the snap-on bezel on the front panel, the 15 disks are visible. Disk numbers, as reported by system commands, range from 1 to 15. When facing the front panel, Disk 1 is located in the leftmost slot in the enclosure and Disk 15 in the rightmost slot.

NOTE:The flanges or sheet metal on the ES30 show 0 to 14 but the software will refer to the logical numbering of 1 to 15.

Each disk in the enclosure has two LEDs. The disk’s active LED glows green when the disk is functional. The disk fault LED glows amber when the disk has failed.

If there is a problem with the enclosure, the enclosure fault light is amber. The disk enclosure power light should be on (blue) when the shelf is powered on.
