Veritas 2U12 49TB Storage Shelf Power Cooling Modules
The Veritas 2U12 49TB Storage Shelf includes two Power Cooling Modules (PCM).
The dual PCMs provide redundant power to the storage shelf. If one PCM fails, the
storage shelf continues to operate as the second PCM continues to supply the
storage shelf with power.
