Installing I/O or Management Module Blanks
To ensure satisfactory EMI levels and to maintain adequate airflow through the BlackDiamond 20808
switch, always make certain that all module slots contain either an installed module or a module blank.
If you remove an installed module, you must install a replacement module or a module blank to ensure
that the remaining modules continue to function correctly.
Save unused module blanks for later re-use in case you must replace a defective module or reconfigure
the switch with fewer active modules.
You need a #2 Phillips screwdriver to install a module blank.
To install a module blank in a slot for a management module or I/O module:
1 Check the condition of the EMI gaskets along the front panel edges of the blank, and confirm that
the gaskets are not damaged.
2 Holding the blank with the screws at the right, align the blank with the slot to be covered
(Figure 48).
Make sure you have the correct blank for the slot. Management modules and I/O modules are
different widths; the blanks for the two module types are not interchangeable.

3 Slide the blank into the slot opening.
4 Align and tighten the retaining screws at the top and bottom of the front panel (Figure 49).
