3 EXECUTIVE SUMMARY This device is a high performance stand-alone SATA RAID hard disk storage system. SATA RAID hard disk storage system's RAID controller has RAID-0 and RAID-0+1 and NRAID modes which can provide up to 2TB hard disk space at RAID-0 and 1TB hard disk space at RAID-0+1. SATA RAID hard disk storage system is very easy-to-use without complicate system setting. Plug-and-play design allows interfacing with a DVR or a PC via SATA cable. With versatile RAID setting, reliable system performance, large hard disk space, low maintenance cost, and plug-and-play interface, SATA RAID hard disk storage system is the best solution for DVR and many other applications. SYSTEM OVERVIEW LCD Indicator System status RAID status HDD status System status Display the status of the storage system. Ready The system is ready to be operated. SysFail Please check jumper settings, SATA cable, and the SATA power connectors. RAID status RAID status can be RAID-0, RAID-0+1 or NRAID which depends on the jumper setting. HDD status HDD status indicates the HDD detected status of all four HDDs. From left to right, HDD symbols represent HDD channels,,,. The status are described as in the following table: Symbol O X F -- Description Installed and detected. Installed but NOT detected. During access, SATA RAID detects HDD(s) failure NOT installed and NOT detected. 2. LED Indicators LED indicator is described as: Red LED HDD failure or system warning.

5 INSTALLATION To install HDDs, follow the following instructions: 1. Power off SATA RAID hard disk storage system. 2. Remove the top cover. 3. Fix the HDDs on the designate area with supplied screws.. Connect SATA cables from SATA RAID Controller to the HDDs accordingly. 5. Connect SATA power cables to SATA HDDs. 6. Set RAID mode jumper if applicable. See RAID mode jumper setting section. 7. Place top cover back. 8. Power on SATA RAID hard disk storage system. 9. Verify HDDs installation on LCD panel. Verify HDDs status To verify HDDs are installed properly, please make sure all "OOOO"areshownonHDDstatus. For example: HDD status is "OXOO" The HDD at SATA port is installed but not detected. 3
6 RAID MODE JUMPER SETTINGS Switch: SW6/SW7 SATA RAID hard disk storage system can be installed for four HDDs at various RAID modes. Please set the switch at the following table: HDD SATA Port SW6 SW7 RAID Mode /// OFF OFF RAID-0 (Stripping) /// OFF ON RAID-0+1 /// ON OFF NRAID Based on different applications, the following RAID mode is highly recommended: 1. DVR application: For DVR application, if one HDD is failure and gets replaced for a new one, the video of the rest HDDs can still be retrieved. There is a risk for loosing the video on the failed HDD. However, if the video is very critical, RAID-0+1 is recommended. 2. Data critical application: If the data is very important, RAID-0+1 is recommended. DISABLE BUZZER To disable buzzer, please set J2 jumper accordingly. J2 : Buzzer ON : 1, 2 ON (default) BuzzerOFF:2,3 ON 321 J2 OFF ON BUZZER
7 DATAACCESS and DATA RECOVERY 1. NRAID data access: NRAID mode accesses HDDs in,, and sequence order. If one of the HDD is failed, please replace the HDD. The data on rest of the HDDs can still be retrieved. 2. RAID-0 data access: RAID-0 mode records data concurrently on all four HDDs. If one of the HDDs is failed, the rest of the data on the HDDs CAN NOT be restored. 3. RAID-0+1 data access: The sequence of data writing for HDDs is from to. and HDDs are mirroring HDDs of and. and are mutual mirroring. and are mutual mirroring. For example, if is failed, please install same brand and size of HDD for. The data on will get transferred to. When RAID controller detects a HDD failure, LCD panel shows "F" for that HDD. Please turn off SATA RAID and replace the HDD. Turn on the power of SATA RAID. A progress counter indicates that the data of backup HDD gets duplicated to the newly installed HDD. After the duplicating process, please turn on the PC or DVR. CONNECTION To connect SATA RAID hard disk storage system to a PC or a DVR, please follow the instructions: 1. Connect SATA cable from SATA RAID hard disk storage system to a PC or a DVR 2. Power up SATA RAID hard disk storage system and make sure all HDDs get recognized and installed. 3. Power up the PC or DVR. 5
