Power modules
The switch supports a power module of model LSUM2AC2500. A LSUM2AC2500 power module is an
AC-input, DC-output power module that provides a maximum DC output power of 2500 W.

Temperature requirements
You can select a certain number of power modules according to the actual power consumption
requirements of your S7508E-X switch. Make sure 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.
Fan trays
The fans trays are shipped with the S7508E-X switch, and have been installed in the S7508E-X switch. If
the fan tray of an S7508E-X switch fails, order a compatible fan tray to replace the failed one.

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 the S7508E-X air filters for the switch as
needed and install the air filters at the air intakes.
