LEDs
If a drive fails or dismounts, the LED will glow as below. To see the status LEDs, open the front cover.
1
Fail LED
Glows amber if a drive has failed.
2
Status LEDs
The failed drive's status LED will be glowing a steady amber. It also glows when the drive is dismounted.
If the RAID array is fragmented by a drive failure, such as in the case of a 3-drive failure in a RAID 6 array, the LEDs
will glow as above and the "SYSTEM DOWN" message will be displayed on the LCD panel.
Notes:
• For the replacement drive, use a Buffalo OP-HDBN/B series drive. The new drive should be the same size as the
replacement drive.
• 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 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.
