That action temporarily disrupts I/O operations and drops your CLU connection.
After the screen goes blank, wait about two minutes, then re-establish your Telnet connection to the CLU. If
you cannot re-establish a connection, wait 30 seconds and try again.

USB support uses the disruptive flash method only. Both RAID controllers and all JBOD I/O modules are updated
at the same time and momentarily go offline when the RAID subsystem and JBOD unit reboot.
This procedure requires a USB flash device:
• Formatted to FAT 32
• At least 50 MB of free space
Download the latest OPAS_xxxxx.zip firmware image file from ASUS Storage support: http://www.ASUS Storage.
com/support/ and save it the root folder of the USB flash device.
Important
Verify that no background activities are running on the RAID subsystem.
To update the subsystem firmware using ASUS DS300f G2's USB Support feature:
1. Insert the USB flash device into the bottom USB port on the front panel which is for the RAID controller.

The controller status LED blinks green in half-second intervals.
2. Wait until the controller activity LED stops blinking green and starts blinking amber.
Warning
Do NOT power off the RAID subsystem during the update!
Do NOT remove your USB flash device until the LED changes color!
3. Within 30 seconds, remove the USB flash device, then insert the USB flash device back into the same RAID
controller.
The remove and insert action confirms that you want to update the firmware.
You can insert the USB flash device back into either USB port but it must be the same RAID controller as
step 1.
4. Wait until the controller activity LED displays steady green.
5. Remove the USB flash device.
