MSA 1050 Array LFF or supported 12-drive expansion enclosure
Figure 3 MSA 1050 Array LFF or supported 12-drive expansion enclosure: front panel
NOTE: Either the bezel or the ear covers should be attached to the enclosure front panel to protect ear circuitry.
You can attach either the enclosure bezel or traditional ear covers to the enclosure front panel to protect the ears, and
provide label identification for the chassis LEDs. The bezel and the ear covers use the same attachment mechanism,
consisting of mounting sleeves on the cover back face:
• The enclosure bezel is introduced in Figure 1 (page 10).
• The ear covers are introduced in Figure 22 (page 58).
• The ball studs to which the bezel or ear covers attach are labeled in Figure 2 (page 10) and Figure 3 (page 11).
• Enclosure bezel alignment for attachment to the enclosure front panel is shown in Figure 21 (page 58).
• The sleeves that push-fit onto the ball studs to secure the bezel or ear covers are shown in Figure 22 (page 58).
Disk drives used in MSA 1050 enclosures
MSA 1050 enclosures support LFF/SFF Midline SAS and LFF/SFF Enterprise SAS disks, and LFF/SFF SSDs. For information
about creating disk groups and adding spares using these different disk drive types, see the SMU Reference Guide.
NOTE: In addition to the front views of SFF and LFF disk modules shown in the figures above, see Figure 26 (page 61)
for pictorial views.
