Disconnecting the EPS-C/EPS-600LS

To manually disconnect an EPS-C or to remove the EPS-600LS modules, the recommended practice is to
disconnect the EPS-600LS modules one at a time, pausing two seconds after each EPS-600LS disconnect.
This enables a graceful power transition from the external power supplies to the internal power supply.
Example: Two active EPS-600LS modules in an EPS-C
a Unplug one EPS-600LS unit from its power source.
PoE power is automatically reduced to 370 watts and the internal switch power supply is
enabled, providing redundant 370 watt PoE power.
b Wait at least two seconds before disconnecting the remaining EPS-600LS unit.
c Unplug the second EPS-600LS unit from its power source.
The internal power supply is already enabled and provides uninterrupted 370 watts of PoE
power.
NOTE
After an EPS-600LS unit is disconnected from its power source, it may be removed from the EPS-C.
See "Removing an EPS-600LS Power Module" on page 283
