Expansion module
The 5U84 expansion enclosure uses the same IOMs that are used by 2U12 and 2U24 enclosures.
The following figure shows the IOM used in supported expansion enclosures for adding storage. Ports A/B/C ship configured
with 12 Gb/s mini-SAS HD (SFF-8644) external connectors. See
for information about indicators on the
enclosure.
