Component Failure Recovery

DataDirect Networks StorageScaler 8460 User Guide | 42

3.2

Component Failure Recovery 

The SS8460 contains redundant and hot-swappable components:

• Power and cooling module

• Disk module

• I/O module

• 5V regulator

• LCD module (hot-swappable only)

A single component failure, therefore, will not shut down the system. However, in the
unlikely event of component failure, you can replace the failed component while the system
is running. The replaced component will automatically be returned to service once the
component has been installed and booted up.

The LCD module is not a redundant component, but the enclosure will remain operational if
the LCD module is broken or if it is removed.

NOTE :

The SS8460 enclosure is designed to remain operational during a service 

action such as replacing a disk module, I/O module, and PCM. During a disk 
replacement, the enclosure management firmware will detect a cover-open 
condition, sound an alarm, and turn on an amber status LED on the front of 
the enclosure. It is recommended that the disks be replaced as soon as 
possible when the cover is open during operation. Leaving the top cover 
open for an extended period will cause an over-temperature condition 
which will sound a continuous alarm. It is recommended that when 
hot-swapping any device in the SS8460, this action be completed within 
5

  minutes to maintain proper cooling. 

Observe all conventional ESD precautions when handling the SS8460 
modules and components. Avoid contact with backplane components 
and module connectors.
