SH4R Shelf
If you install the SH4R in a cabinet, keep in mind that a single,
populated SH4R needs a minimum airflow of 360 CFM. See
Supported Rack Requirements for important supported installation
features and requirements.

Power
The HDsystem supports a centralized power-supply architecture. The PSMs convert the
external DC or AC power to internal 12 VDC, which the system distributes to all modules
through the backplane.
The PSMs work in a redundant power configuration and supply the required power to the
shelf in a load-sharing mode. If a PSM fails, the remaining PSMs continue to supply
power to the entire shelf. You can then replace the failed PSM.
