l Are you using a standard Ethernet cable to connect to the network?
Do not use a crossover cable.
l Have you allowed enough time for the NAS system to boot?
The NAS system typically takes several minutes to boot.
l Does the NAS system boot completely?
Connect a keyboard, mouse, and monitor to the NAS system, and observe the boot process.
l Are the LEDs for all four hard drives on the NAS system lit?
If the LEDs are not all lit, you may have a failed hard drive. See "Software-RAID NAS System Hard-Drive Failures."
Software-RAID NAS System Hard-Drive Failures
Your software-RAID NAS system has a mirror of the operating system on hard drives, which allows you to recover in most cases. Depending on which drive
fails, use one of the procedures in Table6-1 to recover from a hard-drive failure.
Table 6-1. Software-RAID NAS System Hard-Drive Recovery Procedures
Software-RAID NAS System Software Failures
To recover from software failures when the main operating system files are missing or corrupt, manually boot from the recovery operating system mirror hard
drives 2 and 3. For instructions, see "Booting From the Software-RAID NAS System Recovery Operating System Mirror Hard Drives."
Replacing Software-RAID NAS System Hard Drives
This section provides the procedures for replacing hard drive 0, 1, 2, or 3, re-establishing the recovery operating system partitions, and booting from the
recovery operating system mirror hard drives.
Replacing Hard Drives
1. Remove the front bezel.
2. Remove the failed hard drive from the NAS system.
See your Installation and Troubleshooting Guide for information about removing and replacing drives.
3. If you are replacing hard drive 0 and the system is not powered on, move the hard drive in slot 1 to slot 0, and then insert the new hard drive into slot
1 and go to step5. Otherwise, proceed to step4.
This procedure allows the system to boot during step6.
4. Insert a new hard drive in the same location.
5. Replace the front bezel.
Hard Drive That Failed
Necessary Action
Replacing a single failed hard drive
Replace the failed hard drive. See "Replacing Software-RAID NAS System Hard Drives."
Replacing two or more failed hard
drives
Replace the failed hard drives, and reinstall your system by following the procedures in "Reinstalling the Operating
System."
