Install Hard Drives
Once you intall a hard drive on the NSA and create a volume, all existing data
on the disk will be erased. If you want to install two hard drives and configure
them as RAID volumes (see page 17), it is recommended to use the same
disk size and model for best performance.
Hard drives are NOT hot swappable. The NSA must be
turned off before you remove or install hard drive(s).
Creating a volume formats the hard drives. All data will
be lost. Back up any files on the disk to another
location before you install the disk in the NSA.
1. Make sure the power and Ethernet cords are disconnected from the NSA.
2. Loosen the thumbscrews on the rear panel and open it.
