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
• 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,
Caution Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both
module slots must be populated, with either a power supply or a blank module.
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority
or an electrician if you are uncertain that suitable grounding is available.
