Replacing a System Fan
Fan speed is controlled by system temperature, as monitored by the
RAIDar firmware. If a fan fails, the remaining fans will ramp up to full
speed, the overheat/fan fail LED on the control panel will turn on,
and an email alert will be sent to the system administrator.
Replace any failed fan at your earliest convenience. Remove the top
chassis cover while the system is still running to determine which of
the fans has failed.
Follow these steps to replace a system fan.
Note:
System power does not need to be shut down since the fans are
hot-pluggable.
1.
Remove the chassis cover.
2.
Press the tabs on the sides of the fan to unlock and remove the fan and its housing. The
fan’s power connections will automatically detach.
3.
Replace the failed fan with an identical fan. See
"Technical Specifications "
in Appendix A
for fan specifications.
A “click” can be heard when the fan is fully installed in place and the power connections
are made. If the system power is on, the hot-plug feature will cause the fan to start
immediately upon being connected to its header on the main board.
