CAUTION: Power off the device before removing or installing IOMs. IOMs are
not hot-swappable.
Removing a Blank IOM Faceplate
To maintain proper airflow through the device, leave blank faceplates in place over slots
that do not contain IOMs. Do not remove a blank faceplate unless you are installing an
IOM in the empty slot.
To remove a blank faceplate:
1. Unplug the power cord.
2. Loosen the thumbscrews on each side of the faceplate.
3. Grasp the thumbscrews and pull to remove the faceplate.
Installing an IOM
1. Unplug the power cord.
2. Line the IOM up with an empty port on the front of the chassis.
3. Carefully slide the IOM in until it seats firmly in the device.
4. Tighten the screws on each side of the IOM faceplate.
5. Insert the appropriate cables into the cable connectors on the IOM.
6. If necessary, arrange the cables to prevent them from dislodging or developing stress
points:
•
Secure the cable so that it is not supporting its own weight as it hangs to the floor.
•
Place excess cable out of the way in a neatly coiled loop.
•
Use fasteners to maintain the shape of cable loops.
7. Insert the power cord into the AC power receptacle.
