400 W AC-Input Power Supply Specifications (continued)
Description
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 VAC.
34.00 A @ +12 VDC
10 ms minimum
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.
In chassis equipped with dual power supplies, if one power
Note
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.
Green—Power supply fan is operating properly.
•
Red—Power supply fan failure is detected.
•
Off—Power supply is powered off.
•
In chassis equipped with dual power supplies, if one power
Note
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.
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.
In chassis equipped with dual power supplies, if one power
Note
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.
