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.
your 7500 supplier for necessary component. Item Checklist The 7500 package contains the following items. Check that all items listed here are present and in good condition. If anything is missing or damaged, contact your vendor.
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 Disk drive is rebuilding. 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. Otherwise, the 7500 is rebuilding.
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.

Power Connector The power connector supplies power to the 7500 Controller Box.
IDE Connector The IDE connector connects to an IDE 80-pin interface ribbon cable. NOTE: The cable has to meet the specification of UDMA-66 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, Slave, or Cable Select device. Master / Slave / Cable Select jumper If the plastic jumper cap is placed on pins 2-3, the 7500 is set as a Master device.
computer treats the 7500 assembly as one single drive. The drives inside the 7500 must be designated 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.
3. Insert the 7500 Controller Box into the space of two half-height 5 ¼” drive bays, and secure it in place with the screws provided. (If your case uses guide rails to install 5 ¼ ” devices, you can use them on the Controller Box.) IDE Socket Power Cable Pin 1 IDE Cable Power Socket 4. Connect a free power cable to the power connector on the rear side of the Controller Box. 5. Connect an IDE 80-pin ribbon cable connector to the IDE connector on the rear side of the Controller Box.
Loading a Drive in the Drive Carrier NOTE: 1. We recommend that you use identical disk drives in 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.
IDE connector Drive carrier Power connector 2. Place the first disk drive in the drive carrier, so that the power and IDE connectors correspond with the connectors inside the carrier.
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. Make sure the connectors are firmly seated, secure the disk drive with the screws provided, and then slide the loaded disk drive carrier into the 7500 Controller Box. 4. Repeat steps 1 to 3 for the second disk drive. 5. If you have installed two new disk drives go to Application 1.
4. Save your changes to the BIOS setup program and reboot the system. Your system is now ready to start using the 7500 and to automatically mirror all data written to it on two disk drives. 5. If you have installed non-identical hard disk drives, your computer will recognize the 7500 as a single hard disk with a capacity equal to the smaller hard disk drive installed in the 7500.
2. Lock the drive with data and leave the new drive unlocked. This identifies the drive with data as the source drive. NOTE: 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. 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.
DOS and Windows 3.1/95/98, you might not be able to access the extra space if the existing data is stored in an extended DOS partition. Under Windows NT, you can use the Disk Administrator to create new partitions in the extra space of larger drives. 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.
NOTE 2: When the 7500 is rebuilding the data and you shut down the power, do not change any hard disks because the 7500 will remember which disk is the source and which is the target while rebuilding. It also keeps track of the extent to which the data has been rebuilt. So if you change a hard disk in this situation, data error could be the result.
is smaller than the target disk, you can use the 7500 to copy the data on the source disk to the target disk. The function works the same as the “Online rebuding”, but the transfer rate remains UDMA 100 instead of UDMA 133. 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.
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).
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 their 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).
