Note Prior to connecting DC Power to a CDE, consult the Regulatory Compliance and Safety Information for
the Cisco Content Delivery Engine 100/200/300/400 document for important regulation and safety
information.

DC Power Overview

The CDE200, CDE300 and CDE400 can accept DC power (CDE100s do not have a DC power option).
The CDEs can accept power from a –48 VDC (–42 to –56 VDC) source that connects to one (primary)
or two (secondary/redundant) –48 VDC power modules (PMs). Each DC PM must be connected to a
dedicated 60A regulated source. Figure D-1 shows a DC PM for a CDE200.

Note In this chapter, the power supply is referred to as a “power module.”
