Figure 22 DC PEM LEDs

Note With both the DC PEMs installed, both need to be operating with breaker switches on and OUTPUT OK LED on. If

one PEM is not operational, it is recommended that either the PEM be removed from the system or the power input

cables be removed to limit power supply Conductive Emissions (FCC conductive Emission Requirements).

When the power-on sequence is complete, the supervisor card begins to initialize the line cards.
