Power Supply Module
The Cisco ICS 7750 chassis has two slots for power supply modules. At least one
power supply module is required; a second power supply module can be added for
redundant power. With two power supply modules, one module acts as the
primary power supply, and the other power supply is a backup in case the primary
fails. Only one module supplies power to the system at any time. Figure 3-2 shows
the power supply module.
