Chapter 1 Product Overview Power Supplies Send documentation comments to [email protected]. Cisco MDS 9506 Power Supplies The Cisco MDS 9506 Director supports the following types of power supplies: • 1900-W AC power supply (AC input and DC output) • 1900-W DC power supply (DC input and DC output) Power is supplied to the Cisco MDS 9506 power supplies though PEMs in the front of the chassis. The AC power requires an AC PEM, and the DC power requires a DC PEM. The 1900-W AC and DC power supplies are similar in appearance (see Figure 1-11), except for the label that indicates whether the power supply is AC or DC.
