Use when removing a cooling module, as described in the Harmonic
MediaGrid Component Replacement Guide.
Five cooling modules at the rear of the enclosure maintain all system
components below their maximum temperature, assuming the
ambient temperature is below 35°C. Cooling modules can be hot-
swapped while the enclosure is still running, assuming that only one
module is removed at a time and the swap takes no longer than two
minutes. For details, see the Harmonic MediaGrid Component
Replacement Guide.
For a description of LED states, see
LEDs.
Dual PSUs provide redundant power for the system: if one PSU fails,
the other will keep the system running while you replace the faulty
module. For details, see the Harmonic MediaGrid Component
Replacement Guide.
Use when removing a PSU, as described in the Harmonic MediaGrid
Component Replacement Guide.
