LEDs
Drives in the TeraStation show a green status LED during normal operation. If a drive fails, its error LED will glow red.
The following drive replacement examples use the case of the WS5420DN6 series.

Status LEDs
The failed drive's status LED will be glowing a steady red. Dismount the drive in Buffalo Dashboard before
unplugging it from the TeraStation.
Notice Before Drive Replacement
• 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-HDN series drive. The new drive should be the same size or larger. If a
larger drive is used, the extra space will not be usable in a volume.
• 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 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 drives in the TeraStation. For example, pulling out drive 1 and replacing it with
drive 2 may cause data to be corrupted or lost.
