ReadyNAS 4200 Hardware Manual

Replacing a System Fan

Fan speed is controlled by system temperature, as monitored by the

RAIDiator firmware. If a

fan fails, the remaining fans ramp up to full

speed, the overheat/fan fail LED on the control panel turns on, and an

email alert are 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 connection automatically detaches.

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 causes the fan to start

immediately upon being connected to its header on the mainboard.
