Rectifier Module Usage Guidelines
The Valere power shelf supports up to four rectifier modules in 20 Amp or 30 Amp options.
Each Valere power shelf supports up to two C7 shelves.
As a general rule, equip the Valere power shelf with at least one rectifier module per each C7
shelf supported. Additional rectifier modules may be required based on the C7 shelf
configuration, the amperage rating of the rectifier module used, and whether any additional
powered equipment is used in the cabinet. Calix recommends using an N+1 rectifier module
redundancy scheme in all cases.
Use the table below to determine how many rectifier modules to use for your application
based on the total load.

Calix recommends using an N+1 rectifier module scheme for redundancy. The quantity shown represents N only, with no
redundant module.
Note:
When using 20A rectifier modules, loads greater than 3564W per power shelf require
4 modules, prohibiting N+1 module redundancy. If a load is greater than 3564W per power
shelf, use 30A modules instead to allow for N+1 redundancy.
Note:
In the C7 interface (CMS, iMS), the Mount Type parameter at the node level
determines the input power threshold at which C7 shelves report a Power Exceeded alarm.
Thresholds vary by node type. For ODC-1000/2000/3000 cabinets, the threshold is 1620W
per C7 shelf.
