6 If a replacement module will not be installed in the chassis slot, install a blank panel to ensure that
the BlackDiamond20808 chassis maintains proper cooling.
Leave the ESD-preventive wrist strap permanently connected to the chassis; this is to ensure that the
strap is always available when you need to handle ESD-sensitive components.
Installing Switch Fabric Module Blanks
To ensure proper cooling of the XFM-1 modules, always make certain that all five XFM-1 module slots
contain either an XFM-1 module or an XFM-1 module blank. If you remove an XFM-1 module, you
must install a replacement module or a module blank to ensure that the remaining modules continue to
function correctly.
Save all 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 an XFM-1 module blank.
To install a switch fabric module blank:
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 Align the blank with the module slot and slide the blank into place (Figure 54).
3 Using a #2 Phillips screwdriver, align and tighten the captive retaining screws.
