2. To prevent the device from malfunction, please make sure the device is connected with a direct and dedicated power connection of a stable power input.

Chapter 6 Setting the Hard Drive Array Mode

Please select the RAID mode with the jumper located at the back panel. The original default is RAID 1, still there are three pins at the back panel for RAID mode selection:

RAID 0 mode by setting the jumper on the bottom of the two pins.

RAID 1 mode by setting the jumper on the top of the two pins.

1. RAID 0 Mode

1). Place two new hard drives into iR2620 / SR2611 and strongly suggest you to use two identical hard drives to get the equal capacity. If the capacity is different, iR2620 / SR2611 is downward to the small hard drive capacity.

2). Under RAID 0 mode, capacity is add up to a one big volume, also with the feature of faster read/write performance efficient.

2. RAID 1 Mode

1). Place two new hard drives into iR2620 / SR2611 and strongly suggest you to use two identical hard drives to get the equal capacity. If the capacity is different, iR2620 / SR2611 is downward to the small hard drive capacity.

2). Under RAID 1 mode, two hard drives has the identical information as one to mirror to the other one, therefore each of the hard drive failed is still able to function normally. When you replace the failed hard disk to the new one the system automatically rebuilding the data to the newly place hard disk.

Chapter 7 Computer Set Up

When the hardware setup for iR2620 / SR2611 is complete, you are now ready to turn the machine on.

1. After the hardware installation is complete, the iR2620 / SR2611 will be treated as one single hard drive. Set the hard drive to AUTO in the computer's BIOS. When the computer is turned on, the system will retrieve the following information:
2. In iR2620 / SR2611, the installed hard drive can be detected by the Device Manager of Computer Management for Windows.
3. Customers can choose to format the hard drive by using the Disk Management tool of the operating system before using the iR2620 / SR2611.

At this point, the installation process is completely finished. The user can freely retrieve and save data to iR2620 / SR2611 just like retrieving and saving data to a regular hard drive. If the user experiences any abnormality during the operation, please refer to the trouble shooting Q&A section in Appendix.

Chapter 9 Data Rebuilding Operation

The hard drive Hot Swap and Auto Rebuilding functions are available.

(The Hot Swap & Auto Rebuilding functions are applicable in)

1. Off-line Back up

When the data is stored within iR2620 / SR2611, the user can remove one of the hard drives from iR2620 / SR2611 as back up drive for data such as system operation file, secured files, seldom modified files or image and music files. The user can periodically insert the hard drive back into iR2620 / SR2611 to execute automatic backup to protect the system from being hit by computer virus or to avoid risk of having both hard drives failing at the same time.

2. During the Hard drive Failure

When one of the two hard drives fails in the iR2620 / SR2611 system, the system will alarm the hard drive failure message both on the LCD display screen and in the monitoring software. The user can remove the failed hard drive from the system while the system is still in operation without shutting down the machine. If the failed hard drive is replaced shortly, the system will automatically execute the Auto Rebuilding function with out affecting the system operation and without any operation command from the user.

3. The LCD Display Message During Hot Swap and Auto Rebuilding

When the iR2620 / SR2611 detects a hard drive missing or a hard drive failure, the Buzzer will go off and the LCD display screen will display the following messages:

Pri HDD : OK

Sec HDD : Failed

Pri HDD : Failed

Sec HDD : OK

1. After removing the failed hard drive and replacing with a new hard drive, if the hard drive is properly installed, the LCD display screen will display the following messages:

Pri HDD : OK

Sec HDD : OK

1. After few seconds of installing the new hard drive, the LCD display screen will display the data rebuilding progress:

Appendix: Trouble Shooting / Q&A

Unstable system after connecting iR2620 / SR2611

Q: After installing iR2620 / SR2611, we are unable to start the computer or the computer can not locate iR2620 / SR2611 upon startup.

A: 1. Please check whether the readings on the iR2620 / SR2611 LCD display screen appear normal.

1. Please check whether the SATA Cable connection cables are properly connected to the computer system and whether SATA drives are functioning normally.

2. If everything is functioning properly but the user still can not start the computer system, then the problem might be the system incompatibility. If such incompatibility takes place, please contact our technical support department.

Q: When the iR2620 / SR2611 is in use, the computer system is functioning normally but the iR2620 / SR2611 access speed is abnormal.

A: Please first check whether the iR2620 / SR2611 is in the progress of executing data auto-rebuild.

1. Please examine if the length of the connection cables, SATA cable that connect the drives to the computer system is too long and whether the specification these cables complies with the requirements.

2. If both the lengths and specification of the cables are checked out ok, please turn off iR2620 / SR2611 and remove the hard drive from iR2620 / SR2611. Test the hard drive directly with the computer system since it might be the bad sectors in the hard drive that are causing the longer than normal system down time.

Hard Drive Failure

Q: Under the mirror mode (RAID 1), what will be the system's total storage capacity when adding a brand new hard drive?

A: 1. The total storage capacity for iR2620 / SR2611 is determined by the storage capacity of the primary hard drive installed during the initial usage.

1. The storage capacity will not increase after initial installation even when place a brand new hard drive with larger storage capacity.

Q: Why does the error message appear when I installed the second hard drive?

A: 1. The storage capacity of the second hard drive must be larger than the first hard drive. Otherwise, iR2620 / SR2611 can not rebuild the new hard drive and the LCD display screen will display "Wrong Capacity".

1. The LCD display screen might display rebuilding error messages such as Pri(s)->Sec(s)or Sec(s)->Pri(s). The term (s) signifies that both hard drives are treated as original hard drive. The user must determine which hard drive will be the original hard drive prior installing the hard drives into iR2620 / SR2611. Once the original hard drive is designated and installed in iR2620 / SR2611, the user can place in the second hard drive by taking advantage of iR2620 / SR2611's Auto Rebuilding function.

Q: My hard drive is obviously operating properly but why is it shown as failed in the iR2620 / SR2611 display?

A: iR2620 / SR2611 uses more strict requirements and standards to examine the bad sectors in the hard drive. The user can first overwrite the bad sector on a PC before placing the hard drive into iR2620 / SR2611.

About Auto Rebuilding Function

Q: What will happen if we turn off the computer's power while iR2620 / SR2611 is still executing data auto rebuilding?

A: Under the mirror mode (RAID 1), if the power is out of the auto rebuilding process, the controller will remember when completion percentage of the auto rebuilding process and resume the rebuilding process when the power is back on.

Q: Is it possible to lose any part of the data during the data auto rebuilding?

A: The data auto rebuilding function will copy data from one sector to another sector. Technically speaking, the data will not be lost during the auto rebuilding process. However, if the original hard drive is detected with bad sectors during the rebuilding process, iR2620 / SR2611 will make hypothetical duplication instead of treat the bad sectors as hard drive failure. Therefore, the data stored in the bad sectors could potentially be lost during rebuilding.

Q: Under the mirror mode (RAID 1), why does the computer slows down during the data rebuilding process? Or why does the data rebuilding process slows down when the data is being processed?

A: If the iR2620 / SR2611 system is executing data rebuilding simultaneously while the computer system is saving the data, the auto rebuilding process and the saving process will take longer than normal time. This is because the iR2620 / SR2611 must divide it's resource between the normal system operation and the data rebuilding process. However, the priority for the iR2620 / SR2611 is to maintain the proper system operations.

Therefore, the data rebuilding speed will be extremely slow until the system finished with the data saving operations.

Other Possible Situations

Q: The Buzzer will not stop when the iR2620 / SR2611 is in operation.

A: Please check whether the readings on the LCD display are normal or if there is a hard drive failure. Please also pay attention to any other symbols displayed in the LCD display.

For example, if the "F" symbol is displayed, this means that there is a cooling fan failure. If the "T" symbol is displayed, this means that the system is overheated.

Q: How to turn on and off the Buzzer?

A: 1. The manufacture default setting for the Buzzer in iR2620 / SR2611 is Buzzer On.
2. The user can use any pointed materials to push the bottom on the front dash board to turn on and off the Buzzer.
