Description: This attribute is associated with shelf pre-provisioning, and defines a single value for the shelf which applies to both PSFs. The value can be edited by the network manager. A mismatch alarm will be generated against any PSF that does not agree with the value of this attribute. An excess load alarm will be raised against any inserted circuit pack which cannot be provided power without exceeding the actual or provisioned shelf amperage (whichever is less). Auto means when the shelf is equipped, the EC reads the id of the two power filters and takes the value (they should both be the same, but just in case) of the smaller one as the shelf power capacity.

Current configurable values: PSS4: 3.7, 8.5, 20.6. PSS32: auto, 20, 30, 50, 60, 70. PSS16: auto, 20, 35. PSS36: If only PFC power filter is supported, this attribute is read-only, with the value 150. If both PFC and PFB50 power filters are supported, this attribute is provisionable with values auto, 100, 150. PSS64: 275.
