Installing a PowerConnect B-MLXe-4 router
The PowerConnect B-MLXe-4 router ships with slot blanks installed in all empty module slots. The
slot blanks help ensure proper airflow inside the router. You must remove the slot blank to install a
module into a slot.
CAUTION
If you do not install a module in a slot, you must keep the slot blank in place. If you operate the
router with an uncovered slot, the system may overheat. Tighten the screws that secure the slot
blanks so that they remain in place when removing adjacent panels or modules.
Although the slot blanks differ in size, the procedure for removing them is identical. You will need a
flat-blade screwdriver to remove slot blanks.

Follow these steps to remove a slot blank.
1. Loosen the screws on either end of the slot blank by hand or with a flat-blade screwdriver.
2. Pull the slot blank out of the router, and store it in a safe place for future use.
CAUTION
If you are hot-swapping a module, allow a minimum of two seconds after a module (or power
supply or fan tray) has been removed before inserting a module in the same slot.
