without shutdown until maintenance personnel arrive, unless the system is
already in a downgraded operation or failure mode.
A redundant fan module can be installed so that, if one unit fails, the system can
remain in operation.
NOTE: Even if one of the power supplies or cooling fans of a redundant
configuration fails, the system will remain running without shutting down
(downgraded operation). Toshiba recommends immediate repair.
Note that continued downgraded operation could shorten the service life of
various parts of the server depending on the temperature and installation
conditions.
Hard disk drive cage
The HDD (hard disk drive) chassis can hold up to six hot-swappable disk
drives. If you need more disk drives, you can install an expansion HDD cage.
Hard disk drive
Each hard disk drive has its own DC POWER and STATUS indicator LEDs.
The STATUS indicator flashes green while the disk drive is reading or writing
data, but glows amber if something goes wrong with the disk drive when using
the RAID controller (fault status).
HDD status indicators
A set of status lamps, located next to each drive, indicates its condition.
