Weight considerations: 5U expansion enclosure
Before you install, move, or perform service on a 5U SAS expansion enclosure, you must be prepared to handle the weight of the enclosure and its parts.
Safety notices and considerations
Important: Always read and follow the safety notices and instructions before you
install, move, or service the expansion enclosure and its parts. See Safety notices and considerations for information.

Weight of expansion enclosure SAS drives
The SAS drives are shipped in a separate package from the 5U expansion enclosure. The enclosure can support up to 92 SAS drives; however, the quantity varies depending on the number of drives ordered.
Weight increases as FRUs are installed
The 5U expansion enclosure supports up to 92 SAS drives. As Table 2 shows, substantial weight is added to the
enclosure when all drives are installed.
FRU description | Approximate weigh per unit | Maximum supported | Approximate extra weight | ||
---|---|---|---|---|---|
kg | lb | kg | lb | ||
2.5-inch tier 0 flash drive 2.5-inch tier 1 flash drive |
0.224 | 0.494 | 92 | 20.608 | 45.433 |
2.5-inch hard disk drive | 0.304 | 0.670 | 92 | 27.968 | 61.659 |
3.5-inch Near-Line SAS hard disk drive | 0.876 | 1.931 | 92 | 80.592 | 177.675 |
As you install or replace FRUs, the overall weight of the expansion enclosure increases. For
example, Table 3 shows the weight progression
as different combinations of FRUs are installed.
Enclosure assembly | Approximate weight | ||
---|---|---|---|
FRUs installed | FRUs not installed | kg | lb |
|
|
42.5 | 93.7 |
|
|
44.3 | 97.7 |
|
|
58 | 127.9 |
Note: The following FRUs are installed when the enclosure is initially shipped.
|
|
61.5 | 135.4 |
|
|
78.6 | 173.3 |
|
|
86 | 189.6 |
|
|
138.6 | 305.6 |
Conversely, the overall weight of the expansion enclosure is reduced as you remove parts. However, even with parts removed, the 5U expansion enclosure is heavy. Depending on the number of parts that remain, you might need four persons or a mechanical lift to support the weight of the expansion enclosure.
