9.1 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-2400 Login and Access
• Users Cannot Access The NSA-2400
• Backups and Snapshots
• External USB Disks
9.2 Power, Hardware Connections, and LEDs
The NSA-2400 PWR LED does not turn on (no LEDs are on).
• Make sure the NSA-2400 is turned on.
• Make sure you are using the power adaptor or cord included with the NSA-2400.
• Make sure the power adaptor or cord is connected to the NSA-2400 and plugged in to an
appropriate power source. Make sure the power source is turned on.
• Turn the NSA-2400 off and on.
• If the problem continues, contact the vendor.
The NSA-2400 SYS LED is (quickly) flashing red.
If the SYS LED is quickly flashing red then a RAID volume is in degraded mode. Degraded
means one of the disks in the RAID volume is down but the volume can still be used (if you're
using RAID 1 or RAID 5). What you have to do is turn the NSA-2400 off and replace the
faulty disk. See your Quick Start Guide for information on replacing a disk and also
