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
Disk Replacement Restrictions on page 128
.
