12. Mount the replacement IOU by following the removal instructions in Step 7 in
reverse order. Align the IOU with the slot guides, insert it carefully, and secure
it firmly.
Push the eject/lock levers as far as they will go, and then push the knob screws
on the upper and lower eject/lock levers to lock them in position. When the knob
screws remain in position, the IOU is securely mounted.
Note – Mount the dummy (filler) unit in the same manner as IOU. Since the same
levers are used on the dummy (filler) unit, please operate the eject/lock levers in the
same manner.
Note – In hot addition of an IOU, mount the CMU and IOU in the proper location.
Otherwise, the added IOU may not operate.
Caution – Do not forcibly push the IOU when inserting it, even if it is not moving
smoothly. If the IOU is forcibly inserted despite the presence of any obstruction in a
slot or any problem with a connector pin, serious damage may result.
13. Go back to the terminal that is connected to XSCF, and perform the input
operation according to the instructions of the maintenance menu that is
displayed after the replacement.
a. Because the displayed messages are different between active replacement
and hot replacement, perform the operation according to the instructions for
each case. When the display of the maintenance menu returns to the initial
page, the operation is completed.
b. Exit the maintenance menu.
14. Configure the IOU into the system.
■ Active replacement:
Configure dynamically the IOU into a domain by using the addboard
command. Do this operation for all the domains that have been recognized in
Step 2 as including the target CMU.
