Fibre Channel loop IDs:
When you install a drive CRU in the expansion unit,
the drive tray plugs into a printed circuit board called
the midplane. The midplane sets the fibre channel
loop ID automatically, based on the setting of the tray
number switch and the physical location (bay) of the
drive CRU.
Hot-swap hardware:
Your expansion unit contains hardware that enables
you to replace a failed hard disk drive without turning
off the expansion unit. Therefore, you have the
advantage of continuing to operate your system while
a hard disk drive is removed or installed. These
drives are known as hot-swap drives.
Slim-line drives:
You can install slim-line, hot-swap drive CRUs, which
are slightly smaller in size than the standard disk
drive. These drive CRUs do not fill the entire drive
bay. To maintain proper air flow and cooling when
you install a slim-line drive, you must also install one
of the fillers provided in the blank trays.

Installing hot-swap drives:

procedure to install drives in the expansion unit. You can
install additional drives while the expansion unit is powered
up and running.
Note
If you are replacing a drive, see "Replacing hot-swap
drives" on page 88.
