Figure 10-12: When pushing the line card in, do not apply excess pressure
on the left and right edges of the front of the plate. The plate may become
deformed.
Make sure the line card is fitted into both right and left guide rails before
inserting it. If the line card is slid outside of the guide rails, it may cause a
short-circuit.
Push the line card slowly all the way into the slot. Otherwise, improper con-
tact may result. In addition, a failure may result if you insert the line card
too quickly.
4. Tighten the screws on the left and right of the ejectors to fix the line card in
place.
5. Install the communication cable.
Be sure to install a port cap or a loopback cable over line ports that are not
in use. Unless an idle line port is covered with a port cap, dust may get
inside the port and cause a failure.
