Summary#

AC-powered equipment must declare its power rating. The attribute name varies by equipment class.

Description#

Power rating is the primary load specification used by data center power capacity planning tools. The attribute name differs across equipment classes. See the note below.

Why is it required?#

  • Required for power capacity planning and load balancing in facility models

  • Used by electrical simulation runtimes to model power draw

  • Together with EL.001 (voltage) and EL.003 (frequency), fully characterizes the AC electrical input

Attribute Mapping#

Equipment Class

Attribute

CDU

aif:spec:powerRating

CRAH

aif:spec:electricalPowerRating

UPS

aif:spec:upsRating

Applies to#

Equipment with aif:core:assetClass = CDU, CRAH, or UPS.

Note on naming inconsistency#

The UPS uses upsRating (rated kVA/kW output capacity) rather than an input power rating, reflecting the different role of UPS in the power chain.

Examples#

# CDU
def Xform "CW375" {
    float aif:spec:powerRating = 15.0
}

# CRAH
def Xform "CRAH500" {
    float aif:spec:electricalPowerRating = 12.0
}

# UPS
def Xform "UPS5000" {
    float aif:spec:upsRating = 500.0
}

How to comply#

Set the appropriate attribute for your equipment class on the default prim of the *Properties.usda sublayer, using the value from the equipment datasheet in kW (or kVA for UPS upsRating).
