Expansion Shelf Components
An expansion shelf increases the storage available to an array. HPE Alletra 6000 arrays support the HPE Alletra 2140 expansion
shelf. The shelf includes the chassis, two I/O units with cooling fans, four power supplies, and SSDs.
The all flash HPE Alletra 6000 arrays support either one or two HPE Alletra 2140 expansion shelves (depending on the array
model). Each shelf has two I/O units called expanders. Like the controllers in an all flash array, expanders are replaceable in
the field.
HPE Alletra 2140 Front Panel
The front bezel snaps on and off, hiding or exposing the drives within the expansion shelf chassis. During normal operations,
the bezel should remain in place.
The following figure shows the slot designations for the HPE Alletra 2140 expansion shelf.

HPE Alletra 2140 Rear Panel
The rear of the HPE Alletra 2140 expansion shelf includes the expanders and power supplies. Data and power cabling are
done at the rear of the HPE Alletra 2140. The array manages the HPE Alletra 2140 through the expansion cables. There are
no network connectors on an AFS4. The rear components are the same regardless of the model.
