3.1.3 LED indicators for Power Status

The following table is the individual LED which indicates the status of

the backplane voltage signals.

When an LED fails to light up, it means there is a problem with one of the

voltage signals. Please check if the power supply connector is properly

attached to the backplane. If the problem persists, consult with an experi-

enced technician.

3.2 Replacing the Cooling Fan

There are three cooling fans located in the middle of the chassis. All of

them are hot-swappable and provide the system with ample cooling by

blowing air rearwards. To replace the cooling fan, please refer to Figure

out. It will disconnect the cooling fan power connector.

4. Fix the new cooling fan by fastening the thumb screw.
