Installation Guidelines

Table 4-1lists the switches and the compatible power-supply modules. 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.

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 Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
