Chapter 20 Troubleshooting
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
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.
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.
Turn the NSA off, remove the front panel and make sure:
1
• 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
8.2.1 on page
• the hard disk could be faulty. Try a different hard drive or test the original hard disk in a
different NSA or computer.
If you had to replace the drive, turn on the NSA and go to the Storage screen.
2
• 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.
• If you are using a single-disk JBOD volume, you need to create a new volume on the new
drive.
• If you are using a two-disk JBOD volume, you need to create a whole new volume on both
drives.
The LAN LED (by the LAN port) is off.
• Make sure the Ethernet cable is connected properly to the NSA and connected to another
(Ethernet) device. Make sure the other device is turned on. If it's connected directly to a
computer, make sure that the computer network card is working (ping 127.0.0.1 on the
computer).
