Installing a Supervisor Engine or a Module
Make sure that there is enough clearance to accommodate any interface equipment that you will connect
Step 2
directly to the supervisor engine or module ports. If possible, place modules between empty slots that
contain only module filler plates.
Step 3 Verify that the captive installation screws are tightened on all modules installed in the chassis to ensure
that the EMI gaskets on all modules are fully compressed in order to maximize the opening space for the
new or replacement module.
Note
Remove the module filler plate by removing the two Phillips pan-head screws from the filler plate. To
Step 4
remove a module, follow the procedure in the
on page
Step 5 Fully open both ejector levers on the new module. (See
Figure 3-6 Ejector Levers and Captive Installation Screws

Step 6 Depending on the position of the slots in the chassis (horizontal or vertical), perform one of these two
sets of substeps:
Horizontal slot
a.
b.
c.
Caution Do not press down too forcefully on the ejector levers. They will bend and be damaged.

If the captive installation screws are loose, the EMI gaskets on the installed modules will push
adjacent modules toward the open slot, reducing the opening size and making it difficult to
install the replacement module.
3-13.
Position the supervisor engine or module in the slot. (See
sides of the module carrier with the slot guides on each side of the slot.
Carefully slide the module into the slot until the EMI gasket along the top edge of the module makes
contact with the module in the slot above it and both ejector levers have closed to approximately 45
degrees with respect to the module faceplate. (See
Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create
a small (0.040 inch [1 mm]) gap between the module's EMI gasket and the module above it. (See
Figure 3-8.)
