Cisco Cisco VN 2900 Network Adaptation Interface Guía De Instalación

Do not touch the interface card board. Handle the interface card by the edges of the faceplate to reduce 
the risk of damage to the card.

Take one of the following actions:

•

If you are replacing the interface card, use the procedures described in the 

.

Do not connect cables to an interface card until you have installed it.

•

If you are not replacing the interface card, install a blank faceplates over the empty slots to ensure 
proper airflow. (See the

This section describes how to install Cisco interface cards on the Cisco Integrated Communication 
System (ICS) 7750, and contains the following subsections:

Cisco interface cards are installed in the Cisco ICS 7750 through either the multiservice route processor 
(MRP) or analog station interface 81 (ASI 81) cards. For more information about these cards, see the 
“Processor Cards Feature Summary” in 

The MRP has two interface card slots (slot 0, slot 1) and the ASI 81 has one interface card slot (slot 1).

Before installing an interface card into the MRP or ASI 81, perform the following tasks:

Verify that the MRP or ASI 81 card has the minimum Cisco IOS release required to support your 
interface card.

Determine whether additional voice traffic due to installed voice or voice/WAN interface cards will 
require additional digital signal processors (DSPs). If additional DSPs are required, install up to two 
additional packet voice data modules (PVDMs) on each MRP or ASI 81 card to provide more 
processing power.
