About the SATA Storage Enclosure
Disk Drive Spin-up Sequence
The two APC modules in the Storage Enclosure provide enough
power for 12 disk drives to spin up simultaneously. If one APC
fails, drives 1–6 will spin up first, followed by drives 7 and 8,
drives 9 and 10, and then drives 11 and 12. Spin-up is staggered
only on enclosures with one APC.

I/O Modules
The SATA I/O modules have multiple FC Small Form Factor
Pluggable (SFP) receptacles, used to connect hosts or to daisy-chain
the Storage Enclosure to additional enclosures. The FS4100 (JBOD)
has two Host ports and two Expansion ports. The FS4500 (RAID)
module has two Host ports and one Expansion port. The Adaptec
FS4100 I/O module is shown in
