Table 6 Cisco AS5400 Input AC and DC Power Supply Specifications
Input Description Input Specifications
Typical Input Power Requirement 175-320 watts, both AC and DC units
Input Voltage (DC unit) -48 volts nominal, 72 volts maximum
Typical Input Current (DC unit) 3.6-6.6 amps
1,2
Input Voltage (AC unit) 100 to 240 VAC
Typical Input Current (AC unit) 2.0- 3.0 amps
2
Input Frequency (AC unit) 50 to 60 Hertz
CISPR Class B, EN55022 Class B, with 6 dB
Power Factor (AC unit) 0.850 at 50 percent of full load; 0.90 at full load
Electromagnetic Compatibility (EMC) Conducted Standalone CISPR Class B, EN55022 Class B, with 6 dB of margin, standalone
EMC (conducted and radiated, in power shelf) When used in conjunction with PS3000A2-211, meets CISPR Class B with 6 dB margin
1. Power is shown with the normal set points inputs of 120VAC, -48 UDC. These are typical values.
2. Redundant power supplies will automatically configure input voltages on both AC and DCversions. Output load will be auto configured to share between redundant
output modules; no user action is required. All power inputs are given as maximum load power. The maximum power is shown as a function of one redundant power
supply in nonfunction mode, so that the system power can be maintained with one redundant unit.
Table 7 Cisco AS5400 Output AC and DC Power Supply Specifications
Output Description (AC and DC units) Output Specifications

Power Output (watts) 300 watts maximum system load (DC load)
1
Output Current Limit (peak) 350 watts at load, any combination of above voltages and current; units have internal protection
Efficiency (AC and DC units) 67-75 percent load
2
1. Maximum DC load for system cards, DC power will not exceed 300 units.
2. 67-percent at half load.
