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.
2. Please check whether the SATA Cable connection cables are properly connected to
the computer system and whether SATA drives are functioning normally.
3. 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.
2. 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”.
2. 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.
