Component Description
Front bezel
(not shown) The front bezel mounts on the front of the array, and may contain the Visual
Status Beacon light bar, which provides status information for the array. See
Front Bezel Visual Status Beacon on page 78 for more information.
Visual Status
Beacon control sled

If the expansion node uses an active bezel, the drive sled in the upper left
corner of the front of the expansion node provides control for the Visual
Status Beacon. A disk drive cannot be installed in this position.

If the expansion node uses a passive bezel, a disk drive is installed in this
position.
Power button The power button controls the AC power for the enterprise expansion node.
System status LEDs The status LEDs indicate power status, disk and network activity, as well as
hardware faults. See System Status LEDs on page 80 for more information.
Data drives The Verde enterprise expansion node supports up to 23 enterprise disk drives,
or 24 drives if the expansion node uses a passive bezel, mounted on individual
drive sleds in the front of the array. The drive sleds slide into bays in the front of
the enclosure and lock in place. The front of each drive sled has a handle for
removing the sled from the array and a latch for locking the drive sled in place.
Data drive status
LEDs Two LEDs on each drive sled indicate the status of the drive. One LED is for
drive status while the other shows drive activity.
Empty drive sleds When fewer than the maximum number of drives are installed, empty drive
sleds are installed in the unused drive bays to prevent contaminants from
entering the enclosure and to maintain proper air flow.
