Installation Guidelines

Table 1-16lists 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 or fan module 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.
