• Make sure you are using the power adaptor or cord included with the NSA.
• Make sure the power adaptor or cord is connected to the NSA and plugged in to
an appropriate power source. Make sure the power source is turned on.
• Turn the NSA off and on.
• If the problem continues, contact the vendor.
An HDD LED is off.
The HDD LED is off when the NSA cannot detect a hard drive in the drive bay.
Replace or install a hard drive. See Installing or replacing a hard disk.
An HDD LED is red.
Red means that the NSA detected an error on the hard drive (like a bad sector for
example). The NSA automatically tries to recover a bad sector, but the LED stays
red until the NSA restarts. Even if the hard drive still functions, it is recommended
that you replace it since errors are a sign that the hard drive may fail soon. See
Installing or replacing a hard disk.
Installing or replacing a hard disk.
Do not remove or install a hard disk while the NSA is turned on.
The NSA must be turned off before you remove or install the hard
disk.
1 Turn the NSA off, remove the front panel and make sure:
• there is a SATA I or SATA II (3.0 Gbit/s) compatible hard disk installed.
• the hard disk is installed correctly in the disk bay. Push the disk back into the
NSA disk bay until the hard disk is fitted snugly inside the NSA (see the NSA
Quick Start Guide and Section 7.2.1 on page 160).
• the hard disk could be faulty. Try a different hard drive or test the original
hard disk in a different NSA or computer.
2 If you had to replace the drive, turn on the NSA and go to the Storage screen.
• If you have a RAID I volume click the Repair icon next to the new drive.
• If you are using RAID 0 you will need to recreate the whole volume. All of
your data is lost.
