Replacing an I/O Module
CAUTION: Connecting or disconnecting an I/O module or SCSI cable while data
is being transferred causes the loss of data. To prevent errors, always stop all
data transfers on the SCSI bus before removing or installing an I/O module or
SCSI cable.
Some controllers may require removing power when replacing an I/O module or
SCSI cable.
CAUTION: Removing an I/O module significantly changes the airflow within the
tape array, and could cause overheating. Therefore, always replace it as soon as
possible.
To replace an I/O module:
1. Make sure that a current system back up is available.
2. When the controller does not support replacing an I/O module with
power applied, remove power from the tape array.
3. Stop all data transfers.
4. Disconnect the SCSI cables from the I/O module connector 3. Label the
cables as you remove them.
5. While grasping the I/O module handle, press down on the I/O module
latch 1 and pull the I/O module out of the tape array.
