Customers in Europe can obtain Technical Support using the following information: Email: helpdesk@buffalo-technology. ie | Web: www. buffalo-technology. com This user manual uses images representative of TeraStation user interfaces and software. [. . . ] The TeraStation's IP Address, Subnet Mask, Default Gateway Address, and DNS Server address may all be entered manually under IP Address Properties. Click Apply after making any changes. 26 Advanced Settings Network (Workgroup/Domain) To make your TeraStation a member of a workgroup or domain, enter the appropriate information into the fields on this page and click Apply. If the TeraStation is to be part of a Windows Domain, the TeraStation should be added beforehand to the Domain Controller with a computer account in Server Manager. 27 Advanced Settings Disk Management (Drive Properties) This page shows the current properties of your hard drives and RAID Arrays. To change these settings, click on RAID Configuration at left. 28 Note on RAID Arrays TeraStation uses RAID ("Redundant Array of Independent Disks") technology to control the four hard drives in your TeraStation. RAID may be configured several ways: RAID Spanning - All four drives are striped into one large drive, giving the maximum capacity for your TeraStation. This size is the one listed on your TeraStation's box and shows the total capacity of the TeraStation with no data used for redundancy. RAID Spanning is fast and efficient, but with no redundancy, if one hard drive fails, all data on the TeraStation is lost. RAID 1 (mirroring) - Hard drives (or spanned pairs of hard drives) are arranged in mirrored pairs. This costs you half the total capacity of your TeraStation, but provides excellent redundancy. If a hard drive fails, the mirror continues to supply data, so you may work on normally. You may replace the damaged or defective drive at any time, and normal RAID 1 mirroring will then be automatically restored. RAID 5 (parity) - All drives in a RAID 5 array reserve part of their data space for parity information, allowing all data to be recovered if a single drive fails. The parity information takes up about one hard drive's worth of space, so if you set up all four drives in the TeraStation as a RAID 5 array, your usable capacity will be about 3/4 of the total capacity of the TeraStation. After the damaged or defective drive is replaced, your TeraStation will automatically restore all data to the new drive and resume normal RAID 5 operation. Buffalo Technology recommends RAID 5 for its excellent balance of efficiency and security. 29 Advanced Settings Disk Management (RAID Configuration) This page shows your current RAID arrays. You may delete old arrays or create new ones by clicking on the underlined RAID Array # under RAID Array Configuration. You may also disable RAID Array Error Detection Response from this page. Normally, this is set to automatically shut down the RAID array when an error is detected. Though it is not recommended, you may disable that behavior by clicking Disable and then Apply under RAID Array Error Detection Response. Before creating a new RAID array, you may have to delete one or more pre-existing RAID Arrays to clear up the hard drives for your new one. This will destroy all data currently on the disks, so back up any important data before deleting RAID arrays. Whether you want to clear out an old array or create a new one, begin by clicking on the array's underlined RAID Array #, under Name. 30 Advanced Settings Disk Management (RAID Configuration) A configured RAID array may be deleted by pushing the Delete RAID Array button.

See page 23 and page 60 for more information on TeraStation's UPS interface. 59 Advanced Settings Maintenance (UPS Details) Pin 1 2 3 4 5 6 7 8 9 Signal NC RXD TXD NC GND NC NC NC NC Description NC APC_Line_Fail APC_UPS_Shutdown OMR_UPS_Shutdown GND NC +12V OMR_Line_Fail NC This is the connector pin assignment for the UPS serial port on the TeraStation. 60 Advanced Settings Maintenance (Disk Sleep Function) If there are regular periods when your TeraStation is not in use, you may want to schedule disk sleeping. Enable Disk Sleep, select the time that you want to initiate sleep mode, and select the time that you want the TeraStation to "wake up" and resume normal operation. To avoid conflicts, do not use the Disk Sleep Function concurrently with Disk Backup. 61 Advanced Settings Maintenance (Shutdown) From the Shutdown page, press Apply to shutdown TeraStation. [. . . ]
