Replacing a power cooling module
The MediaStore is equipped with two hot-swappable power cooling modules. If one fails, the load
is transferred to the remaining module without interruption to service. To take full advantage of the
redundancy, Harmonic recommends that you use separate, isolated power sources for each AC input.
DANGER:
Observe all conventional ESD precautions when handling Spectrum devices
and components.
CAUTION:
Do not remove the faulty power supply unless you have a replacement of the
correct type ready for installation. Do not leave a power supply slot empty for more than ten
minutes. Doing so will cause the MediaStore to overheat, which will result in component
failure.
1. Make sure that you identify the faulty power supply module.
