Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.

Note The Cisco MDS 9100 Series is only supported for operation with both power supplies and both fan modules installed, with all fans working.

With two power supplies installed, if one power supply fails, the system can continue to function normally on a single healthy power supply. However, the failed power supply should be replaced as soon as possible to provide redundancy.

The fan modules are required to ensure proper cooling of the switches. SeeFigure 2-20, Figure 2-21, and Figure 2-22.
