1Before you start the installation process, read “Safety Precautions” and “Handling Precautions” earlier in this guide.

2Select a chassis slot for your module, following the restrictions and recommendations in “Module Placement in the Chassis” earlier in this guide.

3To expose the selected chassis slot, remove the blank faceplate that covers the slot.

Save this faceplate, because you may need to cover an empty slot in the future. Empty slots must be covered to ensure proper air flow and cooling in the chassis.

4Open the module ejector handles.

5Begin to insert the module:

■In the 7-slot chassis, hold the module horizontally with the LEDs on the left and insert the module using the guides on the left and the right of the slot. See Figure 2.

■In the 16-slot chassis, hold the module vertically with the LEDs at the top and insert the module using the guides on the top and the bottom of the slot. See Figure 3.

CAUTION: Be careful not to twist or bend the module when you insert it.

6Slide the module into the chassis by pushing firmly at the two ends of the front panel near the ejector handles.

WARNING: Hazardous energy levels exist inside of the chassis. Do not place hands or objects into the chassis or touch components on an inserted module.
