Appendix A Power Supply Specifications
400 W AC-Input Power Supply
Branch circuit requirement Each chassis power supply should have its own dedicated, fused-branch
circuit:
• For North America—10 A
• For International—Circuits sized to local and national codes
• All AC power supply inputs are fully isolated.
–
Source AC can be out of phase between multiple power supplies
in the same chassis, which means that PS1 can be operating
from phase
A and PS2 can be operating from phase B.
–
For high-line operation, the power supply operates with the hot
conductor wired to a source AC phase and the neutral conductor
wired either to ground or to another source AC phase as long as
the net input voltage is in the range of 170 to 264
VA C .
Power supply output 34.00 A @ +12 VDC
Output holdup time 10 ms minimum
Front panel LEDs
INPUT OK • Green—Source AC voltage is OK. (Input voltage is 82 VAC or
greater.)
• Red—Source AC voltage is less than 73 VAC (±3 VAC )
• Off—Source AC voltage falls below 70 VAC, is not present, or the
power supply is turned off.
Note In chassis equipped with dual power supplies, if one power
supply is powered on and the other power supply is powered off,
the INPUT OK LED is lit red rather than unlit on the power
supply that is powered off.
FAN OK • Green—Power supply fan is operating properly.
• Red—Power supply fan failure is detected.
• Off—Power supply is powered off.
Note In chassis equipped with dual power supplies, if one power
supply is powered on and the other power supply is powered off,
the FAN OK LED is lit red rather than unlit on the power supply
that is powered off.
OUTPUT OK Green—The 12 VDC output is within margins.
Red—The 12 VDC output is out of tolerance (less than 11.15 VDC or
more than 13.10
VDC).
Off—The power supply is off.
Note In chassis equipped with dual power supplies, if one power
supply is powered on and the other power supply is powered off,
the OUTPUT OK LED is lit red rather than unlit on the power
supply that is powered off.
