Insufficient Inline Power Handling for Supervisor Engine II-TS
When the Supervisor Engine II+TS is used with the 1400 W DC power supply (PWR-C45-1400DC), and
only one 12.5 A input of the power supply is used, the supervisor engine’s power consumption may vary
depending on the type of linecard used and on whether a linecard is inserted at slots 2 and 3. The power
consumption varies between 155 W and 330 W, which also affects the maximum amount of available
inline power through the supervisor engine (0 W to 175 W). Consequently, it is possible for the
supervisor engine to deny inline power to a connected inline power device when one or more linecards
are inserted into the chassis.

The output of the show power detail and show power module commands reveals the variable amount
of power consumption attributable to the supervisor engine and summarizes the supervisor engine’s
inline power.
