Tripp Lite U357-002 owner manual Setting the RAID Mode, When Powered On

RAID Mode

RAID 1 Mode – This mode creates two mirror disk drives for the purpose of data redundancy. If one drive fails, the other drive serves as a back-up. When using this mode, it is recommended that you use hard drives with the same capacities. If hard drives of different capacities are used, the storage capacity will be limited to that of the smaller drive, with the remaining space on the larger drive going unused.

Note: In RAID1 mode, if one of the drives fails, the Red LED to the right of the hard drive tray will blink. Replacing the drive will cause the enclosure to automatically enter rebuild mode, in which the Red LED will continue to blink to indicate that the RAID1 array is being rebuilt. Depending on the size of the drives, this may take several hours to a full day.

Setting the RAID Mode

Note: Make sure that you back up any important data prior to changing the enclosure’s RAID mode. Initializing the RAID mode will erase all data on your hard drives.

When Powered On:

1.Install the hard drives in the enclosure according to the Installation Instructions section in this manual, powering on the unit.

2.By default, the dip switches on the back of the unit are both set to the OFF (Up) position, which will display the hard drives in Normal mode.

3.Set the dip switches on the back of the unit according to the desired mode. See the RAID Mode section in this manual for each mode’s dip switch configuration.

Note: When changing from RAID 1 mode to another mode, you must first switch to RAID 0 mode. Once set to RAID 0 mode, you can change to any other mode.

4.After setting the dip switches accordingly, press and release the Reset button on the back of the unit.

5.After a couple of seconds, your drives will be configured according to the mode you have selected. The new drive will not be formatted, and will need to be formatted using your computer’s Disk Management utility.
