Grounding

The Main 54VDC output shall be provided with isolation between the output and chassis ground. It shall be able

to withstand the following tests:

a) 1500VRMS at 50Hz to 60Hz for 60s.

b) 2250 VDC for 60s.

There shall be no insulation breakdown during the test as defined in sub clause 5.2.2 of IEC 60950-1:2001. The

resistance after the test should be at least 2M ohms when measured at 500VDC.

The VRTN should be isolated from the 12VSB Return and the power module shall support PoE Electrical Isolation

Requirements.

Power Module Failure

There is provision for the connection of dual I2C buses for redundancy.

This enables two master devices to connect to single slave device(s) within the power module.

The power module is provided with a PMBus Management Interface that provides status, measurement and

control data.
