12.1 Troubleshooting Overview

This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories.
•

Power, Hardware Connections, and LEDs

• NSA Login and Access
• Users Cannot Access the NSA
• Backups and Snapshots
• External USB Disks
12.2 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.
• Disconnect the power cord for at least 10 seconds. Reconnect it and turn the NSA back on.
• If the problem continues, contact the vendor.
The NSA SYS LED is (quickly) flashing red.
If the SYS LED is quickly flashing red then a RAID array is degraded. Degraded means one of
the disks in a RAID array is down but the array can still be used (if you're using RAID 1 or
RAID 5). Go to the Storage > Internal Storage > Disk screen to identify the faulty disk.
Replace the faulty disk with another of equal or greater capacity. See your Quick Start Guide
for information on replacing a disk and also
