You can select a certain number of power modules according to the actual power consumption
requirements. Make sure that the total maximum output power of the ordered power modules is greater
than the system power consumption. H3C recommends that you reserve 20% of the maximum output
power.
NOTE:
•
Power modules of different models cannot be installed on the same gateway.
• When the temperature of a power module exceeds the normal operating temperature, the power
module is automatically powered off. When the temperature recovers to the normal temperature, the
power module is automatically powered on.
Fan trays
Table 21 shows the fan trays that each M9000 gateway supports. Every M9000 gateway comes with
fan trays installed.

NOTE:
When the fan tray is damaged and needs to be replaced, select a new fan tray compatible with your
gateway.
Air filters
CAUTION:
Clean air filters periodically (at least once every three months) to guarantee adequate ventilation and
avoid over-temperature.
To prevent dusts from entering the chassis, you can configure air filters for the gateway as needed and
install the air filters at the air inlet vents.
