Step 6 If you have an ISDN BRI module with an integrated NT1 device, use a

straight-through RJ-45-to-RJ-45 cable to connect the ISDN BRI (RJ-45) port to

an RJ-45 or RJ-11 jack. (See Figure 3-25.)

Step 7

If the router is conﬁgured with fewer than three WAN modules, install a blank slot

cover over each open slot to ensure proper airﬂow.

Step 8 Using an M 3.5 thread-forming screw (not included), attach a ground wire to the

protective grounding terminal on the rear panel of the chassis.

Step 9 Connect the power cable to the router and the power source.
