Installation Guidelines
Observe these guidelines when removing or installing a power supply or fan module:
• 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 under
these circumstances:
• The switch is in StackPower mode and sufficient power is available.
• The switch is powered by other switches in a power stack, and no active backup is in progress.
For the switch commands that display available power budget, see the software configuration guide.
