Red if a drive has failed.
2 Status LEDs
Green: Normal operation.
Glowing red: If a drive's status LED is glowing red, the drive has malfunctioned. Dismount the drive in Buffalo
Dashboard before unplugging it from the TeraStation.
Notes:
• Do not unplug a drive whose status LED is not lit red. If you remove the drive without properly dismounting
it, data may be lost or the TeraStation may malfunction.
• For the replacement drive, use a Buffalo OP-HDWR series drive for WS5000N2 series and a OP-HDS series drive
for WS5000R2 series. The new drive should be the same size (or larger) as the replacement drive. If a larger
drive is used, the extra space will not be usable in a RAID array.
• The TeraStation is fragile. Handle it with care. Do not drop or bump the TeraStation.
• Use caution when handling the unit in order to avoid personal injury.
• Never disassemble any parts while you are replacing a hard drive unless instructed to do so in this manual.
Any malfunction or damage caused by disassembling the TeraStation will void your warranty.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of
metal before handling any sensitive electronic parts.
• Do not change the order of the hard drives in the TeraStation. For example, pulling out drive 1 and replacing
it with drive 2 may cause data to be corrupted or lost.
• The boot drive (C:) consists of the mirrored volume and a portion of the two drives from the top. Do not
replace both of these hard drives at the same time.
• If a hard drive is replaced while saving a file, the file can be corrupted. Be sure that the saving operation is
completed before replacing the hard drive.
