Configuring the Port Multiplier Using Switches
Resetting the RAID
NOTE: This procedure destroys all RAID data. It should not harm individual drives or their contents; however, creating backups of all data is strongly recommended before proceeding.
Be sure the port multiplier is connected to an active host before proceeding. The port multiplier will not complete the process if it has no host connection.
1.Power down the unit and set the switches to the desired RAID Mode.
2.While holding the SET/RESET button, turn the unit on. A long beep will sound from the Port Multiplier. The SET/RESET button may be released once the long beep starts.
Shortly after releasing the button, the port multiplier should “chirp” to indicate the process is complete. If instead of a chirp the Port Multiplier sounds a series of short beeps, an error has occurred during the process.
Setting or Modifying the RAID Mode
NOTE: Setting or modifying the RAID mode destroys all data.
Be sure the port multiplier is connected to an active host before proceeding. The port multiplier will not complete the process if it has no host connection.
1.Follow the procedure for resetting the RAID Mode.
2.Power down the unit and set the dip switch to the desired RAID Mode.
3.While holding the SET/RESET button with a ballpoint pen, turn the unit on. A long beep will sound from the Port Multiplier. The button may be released once the long beep starts.
Shortly afterward, the port multiplier should “chirp” to indicate the process is complete. If instead of a chirp the Port Multiplier sounds a series of short beeps, an error has occurred during configuration of the array.
RAID Mode Switches (SW1:3 – SW1-5)
The RAID Mode switches define what type of RAID will be initialized when the unit is powered up while the button is held down, as follows:
