Power Shelf
The type of CRU installed in slots 50 and 55 determines whether that enclosure
requires a power shelf. Enclosures without power shelves have power supplies internal
to the CRUs in slots 50 and 55. Enclosures with power shelves have external power
supplies.
The power shelf is installed under the enclosure chassis.
AC power is supplied to the power shelf through AC power cords that connect to the
power supply through the sheet-metal bulkhead in the center of the power shelf. AC
power for enclosures without power shelves is provided by AC power cords connected
directly to the PMF CRUs or IOMF CRUs.
