Connect DC Power to the Switch
Complete the following steps to connect DC power to the switch:
Note Connect the MGX 8950 switch only to a –48 VDC source that complies with the Safety Extra Low
Voltage (SELV) requirements in IEC 60950/EN 60950.
If you are installing redundant DC PEMs, you can connect to the same power source if you do not require
the additional fault tolerance offered when using separate power sources.
Step 1 Verify that the power source to the switch is turned off and that the circuit breaker on the DC PEM is off.
