Equipment Replacement
Step 17
After all modules have been transferred to the replacement unit, remove the PIU being replaced from the blade,
and set it aside for repair paperwork processing.
Step 18
Carefully align and install the replacement PIU into the appropriate slot.
Note: The PIU should be slowly and carefully inserted into the blade to prevent damage to the PIU and/or
blade. When the connector pins of the PIU engage the backplane, the PIU must be fully seated within 10
seconds. If it takes longer than 10 seconds to install the PIU, an equipment fault alarm may be raised.

Step 20
Remove the optical connector covers, if necessary, and carefully press the LC connector tab on each of the I/O
fiber-optic cables to carefully install each cable into its correct connector on the PIU.
