Product Description Product Description The AC PEM provides power conversion directly from the facility VAC input power (100 VAC to 240 VAC) to the –48V VDC used internally by the system (see Figure 1). AC power is delivered to the AC PEM from the VAC connection power cable to the power cord attached to the PEM.
Prerequisites and Preparation Before you perform any of the procedures in this guide, Cisco recommends that you: Read the safety guidelines in the next section and review the electrical safety • and ESD-prevention guidelines in the Cisco 10000 ESR Hardware Installation Guide.
Installation Guidelines This warning symbol means danger. You are in a situation that Warning could cause bodily injury.
