ASUS Storage DS300j User Manual
Replacing an I/O Module
The I/O module monitors and manages the logical drives. When the I/O module
is replaced, all of your logical drive data and configurations remain intact because
this logical drive information is stored on the disk drives.
I/O modules rarely fail. But you might have to remove and reinstall the same
I/O module in order to replace a cooling fan as described in this chapter.
Caution
•
Do not replace the I/O module based on LED colors alone.
Only replace the I/O module when directed to do so by ASUS
Technical Support. See page 44.
•
Only a qualified technician should perform this procedure.
•
You must shut down the ASUS Storage DS300j unit before
you can perform this procedure.
