Powering on the RouterThis chapter describes how to connect the power modules in the chassis and to power on the router.• Power Supply Overview, on page 1• Power Connection Guidelines for AC-Powered Systems, on page 2• Connect AC Power to the Chassis, on page 3• Connect a DC Power Supply to the Chassis, on page 14Power Supply OverviewYou can install up to four 3.2KW AC or 3.2KW DC power supplies in the chassis. Ensure that all powerconnection wiring conforms that to the rules and regulations in the National Electrical Code (NEC) and inlocal codes.The Cisco 8608 chassis doesn't support a mix of AC and DC Power Supply Units (PSUs).NoteAC Power Module• The AC power modules are single feed with 3.2KW capacity at 220V. They also support operation at110V with half the capacity of 1570W.• AC power modules are rated at 3.2KW maximum at 230V AC high line input, and 1570W maximum at115V AC low line input.• AC nominal range: 100—120V AC and 200—240V AC• AC full range: 85—132 V AC and 180—264V AC; with extended range to 300V ACDC Power Module• The DC power modules are dual feed with 3.2KW capacity at any specified input voltage. DC powermodules with single feed at any specified input voltage provide up to 1.6KW maximum capacity.• DC nominal range: -48 to -60VDC• DC full range: -40 to -75VDCPowering on the Router1
