The Rear of the System
SpycerNode
Power Supply Unit (5U Enclosure)
Dual PSUs provide redundant power for the system: if one PSU fails, the
other will keep the system running while you replace the faulty module. The
PSUs are hot-swappable. Replacement of a PSU can be performed while
the enclosure is running, but the procedure must be completed within two
minutes of the removal of the defective PSU. Ensure you have a replace-
ment PSU before you remove the defective PSU.
The enclosure chassis is keyed to prevent PSUs from being inserted upside
down.
