•INPUT OK
|
•Green—The source DC voltage is OK. (-38.25 VDC or greater.)
•Off—The source DC voltage has dropped below -33 VDC or is not present.
Note In dual power supply configurations with the alternate power supply powered up, the INPUT OK LED may be lit red to indicate that the DC input voltage is less than -33 VDC or that the power supply is switched off.
|
•FAN OK
|
•Green—The power supply fan is operating properly.
•Red—A power supply fan failure is detected.
|
•OUTPUT OK
|
•Red—A problem with the DC-output voltage from the power supply is detected.
•Green—The DC-output voltage is within acceptable margins.

Specification

Description
|
AC-input type
|
Autoranging input with power factor correction (PFC)
Power factor correction (PFC) reduces the reactive component in the source AC current allowing higher power factors (typically 99 percent or better) and lower harmonic current components.
|
AC-input voltage
|
•Low-line (120 VAC nominal)—85 VAC (min) to 132 VAC (max)
•High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)
|
AC-input current
|
5 A
|
AC-input frequency
|
50/60 Hz (nominal) (±3% for full range)
|
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 VAC.

|
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.
