Chapter 4 Installing and Removing MSCs, PLIMs, and Associated Components
Recommended Order of Card Installation
We recommend the following order when removing the impedance carriers and installing the cards in
the chassis
card chassis):
Install the RP cards first one card at a time, the left one (slot RP0) before the right one (slot RP1). Tighten
Step 1
the screws only after fully inserting both RP cards.
Note
Install the switch fabric cards one at a time in the same manner.
Step 2
We recommend that you install fabric cards from left to right, starting from top to bottom, in this order:
•
•
•
•
Step 3 For the MSCs and PLIMs, you must remove one impedance carrier, install a functional board, and
tighten the screw; then repeat the process until all cards and PLIMs have been installed.
Cautions and Recommendations
When you remove a card, always use the ejector levers to ensure that the connector pins disconnect from
Caution
the midplane in the sequence expected by the router.
Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or install
only one card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before
removing or installing another card.
Do not operate the Cisco ASR 14000 series 8-slot line card chassis with any slots completely empty;
doing so could lead to an airflow bypass condition that diverts airflow from slots containing
heat-generating electronics, possibly causing thermal alarms to occur at lower-than-expected ambient
temperatures.
To avoid airflow bypass, all slots should be filled with their appropriate cards or impedance carriers. If
you have to replace a card, we recommend leaving the card in place in the chassis until you are ready to
install the new one.

(Figure 4-3 and Figure 4-4
It is important to engage and partially tighten all screws first, before fully tightening them with
a screwdriver. This action helps ensure that all parts are aligned properly in the chassis.

To lessen the possibility of damaging the connectors on the chassis midplane, you should
visually inspect the connector pins on the cards before you insert them into the chassis.
