Power system
Restrictions and guidelines
Before you order a power module, make sure you have read the following restrictions and guidelines:
• A chassis must be configured with a minimum of one power module. To improve power supply
availability, you can configure a chassis with two power modules for redundancy.
• The power modules installed on an S7500E switch must be the same type (AC or DC) and model.
• Make sure the maximum output power of a power module is greater than the total power
consumption of the switch. H3C recommends that you reserve 20% of the maximum output power.
For more information about the total power consumption, see "Appendix A Chassis views and
technical specifications."
• If you want the switch to provide PoE power for PDs, order a power module that can be used for
setting up a PoE system. Make sure the maximum PoE power provided by the power module is
greater than the PoE power consumption. The requirements for setting up a PoE system vary by
switch model. For more information about setting up a PoE system, see "Installing FRUs."
