Step 7 If you are installing a replacement card, proceed to the next step. Otherwise, install a blank cover over the slot and screw down its captive screws to conclude this procedure.

Note For proper cooling and airflow, a cover must always be installed in a blank TCC+ card slot. The product order number for the blank TCC+ card cover is UBR10-TCC+-COVER=.

Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place. Statement 1029

Step 8 Pick up the replacement TCC+ card and position it in front of the card cage slot.

Step 9 Carefully align the upper and lower edges of the line card with the upper and lower guides in the chassis, and slide the line card into the slot so that it firmly seats in the backplane connectors (see Figure 5-35).
