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.

Featuring intelligent online recovery, the 7500 lets you hot swap a failed drive and the 7500 automatically rebuild the data to the new drive without any system down time. The 7500 Controller Box features a user-friendly rack design that lets you easily install a backup drive, or replace a drive that fails. Each hard drive carrier supports a one-inch high

3.5-inch form factor disk drive. Additional data security is provided by a key-locking system, that prevents unauthorized access to each disk drive.

7500 supports all hard disk manufacturer IDE hard drives that confirm to the industry hard disk standard as IBM, Quantum, Maxtor, Seagate, Samsung, and Fujitsu. 7500 also supports Western Digital hard drive but please contact your 7500 supplier for necessary component. The location and distance between IDE and Power connector in 7500 drive carriers follow the specification in AT Attachment (ATAPI spec). The IDE connector of the Western Digital disk drive has a 1-2 mm alignment difference compared to drives of other brands. Therefore, please specify before you ordering 7500 or contact

About Drive Carriers:

Each drive carrier can hold a one-inch high 3.5-inch form factor IDE disk drive. This makes it easy to hot swap a drive in the event of a failure, without affecting the status of the remaining drive.

Indicators

Disk Activity Indicators

These indicators show the status of each individual disk drive.

English - 6

Indicator Disk Activity

Green Disk drive is properly installed and locked Amber Disk drive is being accessed Red 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.

Disk Status / Rebuild Indicators

The upper indicator represents the top drive carrier, the lower indicator represents the bottom drive carrier. If a drive fails, the appropriate indicator turns on and an audible alarm sounds. You can turn off the audible alarm by unlocking the drive carrier. The red Indicator of the target disk will light up and blink while rebuilding.

Rebuilding Activity / Error Message Indicator

Rebuilding Activity:

This row of eight indicators shows disks rebuilding activity. In normal operation, a green light scans across the bank of indicators. If you are using the online recovery feature to rebuild a drive, all the indicators will turn on at the same time. The left-side indicator blinks and then turns off when 12.5% of the data has been mirrored. Then the next indicator blinks and turns off when 25% of the data has been mirrored, and so on.

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.

T wo 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.

Error Message:

The chart offers the all-possible error messages, and can help you to identify certain problems.

★ Drive Carriers LED Error Status Display

☆ Disk Fail (Replace the failed disk with another disk)

☆ Target Disk Size small than Source Disk (Replace the

failed target disk with a disk that’s size is greater or equal to the source disk.)

☆ Target Disk UDMA Mode small than Source Disk

(Replace the failed target disk with a disk that’s UDMA mode is greater or equal to the source disk.)
