Welcome Congratulations on your selection of the 7500. The 7500 are a reliable and affordable solution for RAID 1 disk mirroring. With a cost effective IDE approach, the 7500 mirrors data to two disk drives simultaneously, and delivers optimized performance, comparable to more costly SCSI based solutions. If one drive fails, data is secured by the other drive and alarm sounds to alert you.

System Requirements The 7500 can be installed inside a computer that meets the following hardware specifications: System with IDE/AT interface Case with two half-height 5 ¼” drive bays with front bezel access One IDE channel cable connector One free power supply connector Front Panel Components Disk activity indicators Top drive carrier Top Drive carrier lock Disk status / Rebuild indicators Rebuilding activity / Error message indicator Bottom Drive carrier lock Bottom drive carrier Disk activity ind

Indicator Green Amber Red Disk Activity Disk drive is properly installed and locked Disk drive is being accessed Disk drive is not present, is not properly installed, is unlocked, or disk has failed Note: Sometimes you can see the red disk activity LED showing the 7500 is booting, This is because the 7500 is searching for a disk, as soon as it has found one, the red LED will turn off.
PAGE 8
Drive Carrier Locks The driver carrier lock acts as an On/Off switch for the drives and provides security by preventing non-key holders from accessing the drives. When you lock the drives, the first drive to get locked is designated as the source drive and the other drive becomes the backup drive. Two identical keys are provided with the system. To lock each carrier, insert the key and turn it in a clockwise direction. To unlock a carrier, turn the key in a counterclockwise direction.

cable. NOTE: The cable has to meet the specification of UDMA66 and above. Master / Slave / Cable Select Jumper (JP1) This jumper allows the 3 2 1 user to set the 7500 up as JP1 either an IDE Master, Master / Slave / Cable Select jumper Slave, or Cable Select device. If the plastic jumper cap is placed on pins 2-3, the 7500 is set as a Master device. If the jumper cap is completely removed from the pins, the 7500 is set as a Slave device.

as Master devices. Installation Mounting Controller Box in System CAUTION: Turn off and disconnect all electrical power from the system before beginning any installation procedure. 1. Determine if you are installing the Controller Box as a Master or Slave device. Remove the jumper cap from the Master/Slave jumper if the Controller Box is a slave device. 2. Remove the cover and front bezel from the system case. 3.

the two drive carriers. The hard disk drives must be configured as Master devices. 2. 7500 supports the most models of the following hard disk brands: IBM, Quantum, Maxtor, Seagate, Samsung, and Fujitsu. 7500 also supports Western Digital hard drive but please contact your 7500 supplier for necessary component. 1. Unlock the drive carriers and slide them out of the Controller Box.

2. Place the first disk drive in the drive carrier, so that the power and IDE connectors correspond with the connectors inside the carrier. Disk drive Screws 3. Connect the power connector to the disk drive first, then carefully push the disk drive in so that the drive’s IDE and power sockets seat into the IDE and power connectors in the disk carrier.

4. Repeat steps 1 to 3 for the second disk drive. 5. If you have installed two new disk drives go to Application 1. If you have installed one drive with data and one new disk drive go to Application 2. Application 1: Two new disk drives (identical or non-identical) 1. Lock both drive carriers. 2. Turn on the computer system. 3. When the system prompts you to enter the BIOS setup program shortly after power-on, follow the instructions and enter the BIOS setup program. Set the hard disk drive mode to “Auto”.

installed in the 7500. The status of all indicators during boot-up: Please be sure to put two hard disks into the two drive carriers while the 7500 is booting, and lock it on before powering on.

3. Turn on the computer system. 4. When the system prompts you to enter the BIOS setup program shortly after power-on, follow the instructions and enter the BIOS setup program. Set the hard disk drive mode to “Auto”. 5. Save your changes to the BIOS setup program and reboot the system. 6. After the boot process is complete, lock the new drive. This identifies the new drive as the backup drive. 7. The system will immediately begin mirroring the data from the first drive to the backup drive.
PAGE 18
Online Rebuilding feature The online Rebuilding feature allows you to hot swap a failed disk drive with a new one, automatically recovering all data to the new drive with no system down time. When the Controller Box alerts you that a drive has failed, follow these instructions. 1. Leave the system turned on. Unlock the carrier of the disk drive that has failed and slide it out of the 7500 Controller Box. NOTE 1: The 7500 will continue to save data to the remaining disk.
PAGE 19
you change a hard disk in this situation, data error could be the result. For example: If you change the target hard disk in this situation, the 7500 will continue rebuilding the data from where it left off so that the first amount of data will not be stored on this new target disk. That means the new disk will not have the data that was already copied onto the hard disk that was replaced.
PAGE 20
NOTE 5: When the power disconnected when rebuilding, the 7500 will continue the data rebuilding when the power returns, instead of rebuilding from the beginning. It is because there is a build-in battery inside 7500; it offers the memory on rebuilding status when the power is interrupted. Under normal application the battery will work for around 3 years. If necessary, please replace with the same type of battery and read carefully the use instruction on the battery.
PAGE 21
Troubleshooting If you encounter a problem while installing or using 7500, check this section for help. 1. I cannot connect a Western Digital hard drive into the connectors of the drive carrier. There is a specially designed drive carrier for the Western Digital disk drive. Please specify before you ordering. The location and distance between IDE and Power connector in 7500 drive carriers follow the specification in AT Attachment (ATAPI spec).
PAGE 22
3. When I lock the second drive carrier with a disk drive in place, the red activity indicator turns on and an alarm beep sounds (The first Drive Carrier has already been locked without any problem). (a) Make sure you firmly connect the IDE and Power connectors of hard disk to the ir counterparts inside the drive carrier and try again. If this does not solve the situation, go to (b) (b) Check if the capacity of the second disk drive is equal or bigger than the first one.

disk. I then discover both disks are rejected and I hear the beeper when I power on the 7500 again. How do I solve this problem? The 7500 can’t ascertain user’s action without power. But when in operation, it always remembers that status of the work. For example: which disk is source, which one is target, and the extent the data or only has one hard disk. The 7500 will remember this situation while it’s rebuilding data or only has one hard disk.

can’t be accessed normally. The 7500’s specifications are based on ATAPI specifications. To ensure good IDE signal quality, the length of your IDE cable cannot be longer than 46 cm (18 inch).
