Q: Can I hot-swap a failed drive with a new drive?
A: Yes. Disk drives are hot-swappable on the Symantec Storage Shelf.
Q: Can the Symantec Storage Shelf run using just one power supply?
A: Yes, it is possible to run the Symantec Storage Shelf on a single power
supply. However, leaving one power supply off means there is no redundancy
if the other power supply fails. Also, omitting one power supply and its fans
reduces air flow through the enclosure, which can contribute to overheating.
Always switch on both power supplies.
