5U84 Storage Shelf Power Supply Units
5U84 Storage Shelves includes dual Power Supply Units (PSU) that provide redundant power to the storage shelves. If one PSU fails, the storage shelves continue to operate as the second PSU continues to supply the storage shelf with power.
PSUs are hot-swappable. You can replace a faulty PSU while the storage shelf is running. However, you must complete the PSU replacement procedure within two minutes after you remove the faulty PSU.
5U84 Storage Shelf chassis are keyed to prevent PSUs from being inserted upside down.
The rear panel of the PSU includes a power switch, three status LEDs, and an AC socket for the power cord. The rear panel also includes a handle that you use during the PSU insertion and removal process.
