Figure 7. Attaching or removing the 2U enclosure front bezel
You can attach or remove the optional 2U enclosure bezel. Locate the bezel, and while grasping it with your hands, face the front panel of
the 2U12 or 2U24 enclosure. A partial view of a 2U12 enclosure is shown in Attaching or removing the 2U enclosure front bezel.
1. Hook the right end of the bezel onto the right ear cover of the storage system.
2. Insert the left end of the bezel into the securing slot until the release latch snaps in place.
3. Secure the bezel with the keylock as shown in Attaching or removing the 2U enclosure front bezel.
To remove the bezel from the 2U enclosure, reverse the order of the preceding steps.
NOTE:
See Enclosure variants for details about various enclosure options.
Enclosure variants
The 2U chassis can be configured as a controller enclosure ME4012/ME4024, or an expansion enclosure ME412/ME424 as shown in 2U12
enclosure variants and 2U24 enclosure variants. The 5U chassis can be configured as a controller enclosure ME4084 or an expansion
enclosure ME484 as shown in 5U84 enclosure variants.
NOTE:
The 2U and 5U core products—including key components and CRUs–are described in the following sections. Although
many CRUs differ between the form factors, the controller modules and IOMs are common to 2U12, 2U24, and 5U84
chassis. The controller modules and IOMs are introduced in 2U enclosure core product and cross-referenced from 5U84
enclosure core product.
2U12
2U12 enclosures consist of 12 x LFF (Large Form Factor) disk drives and 12 x HFF (Hybrid Form Factor) disk drives.
