Do not force the power supply or fan module into the slot. This can damage the pins on the switch
if they are not aligned with the module.
A power supply that is only partially connected to the switch can disrupt the system operation.
Remove power from the power supply module before removing or installing the module.
The power supply is hot-swappable. In some configurations, such as full PoE+ or power-sharing
mode, removing a power supply causes powered devices to shut down until the power budget
matches the input power of a single power supply. To minimize network interruption, hot swap the
power supply ensuring that the remaining supply has sufficient PoE power for all powered ports.
For the switch commands that display available power budget, see the software configuration guide.
