HPE MSA 2050 models support small form factor (SFF) and large form factor (LFF) enclosures. The SFF chassis,
configured with 24 2.5" SFF disks, and the LFF chassis, configured with 12 3.5" LFF disks, are used as either controller
enclosures or drive enclosures.
Supported drive enclosures, used for adding storage, are available in LFF or SFF chassis. The MSA 2050 LFF Disk
Enclosure is the large form factor drive enclosure and the MSA 2050 SFF Disk Enclosure is the small form factor drive
enclosure used for storage expansion.
HPE MSA 2050 models use either an enclosure bezel or traditional ear covers. The 2U bezel assembly is comprised of left
and right ear covers connected to the bezel body subassembly. A sample bezel is shown below.
Figure 1 Bezel used with MSA 2050 enclosures: front panel
The front panel illustrations that follow show the enclosures with the bezel removed, revealing ear flanges and disk drive
modules. Two sleeves protruding from the backside of each ear cover component of the bezel assembly push-fit onto the
two ball studs shown on each ear flange to secure the bezel. Remove the bezel to access the front panel components.
TIP: See “Enclosure bezel” (page 62) for bezel attachment and removal instructions, and pictorial views.
