Installing Switch Fabric Modules
Five XFM-1 switch fabric modules are installed in dedicated slots at the rear of the BlackDiamond 20808
chassis.
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 installed XFM-1 module,
you must install a replacement module or a module blank to ensure that the remaining modules
continue to function correctly.
CAUTION
Install the XFM-1 module only in a BlackDiamond 20808 chassis.
To install an XFM-1 module:
1 Attach the ESD-preventive wrist strap to your bare wrist and connect the metal end to the ground
receptacle on the back of the chassis.
2 Identify the slot where the module will be installed.
3 If necessary, remove a blank panel from the chassis slot.
NOTE
Save unused XFM-1 module blanks, in case an XFM-1 module must be removed from the chassis later. Module
slots must always be occupied by either an XFM-1 module or a module blank.
