17.2 Power, Hardware, Connections, and LEDs
The NSA PWR LED does not turn on (no LEDs are on).
• Make sure the NSA is turned on.
• 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.
The 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 drive.
The HDD LED is orange.
Orange 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 orange 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 drive.
The HDD LED is red.
Red means the hard drive has failed and the NSA can no longer detect it. Replace
the hard drive. See
Installing or replacing a hard drive. If you are using a RAID I
volume, you may still be able to use the volume but you should replace the faulty
drive as soon as possible.
