SCA Backplane
The SCSI drives plug into a SAF-TE compliant SCA backplane that provides power,
SCSI ID and bus termination. A RAID controller can be used with the SCA backplane
to provide data security. The operating system you use must have RAID support
to enable the hot-swap capability of the SCSI drive. The SCA SCSI backplane is
already preconfi gured; there are no jumpers or switches.

Removing the air shroud
Under most circumstances you will not need to remove the air shroud to perform
any service on the system. However, if you wish to temporarily remove it (the air
shroud sould always be in place when the system is operating), please follow this
procedure.
Begin by depressing the tabs at the front and rear of the shroud to unlock it, then
lift it up and out of the chassis. To reinstall, simply position the air shroud in its
proper place and push it in until you hear it click.
