OL-12842-01
Caution
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
“Installing Blank Faceplates” section on page 7
.)
Tip
See the
“Where to Go Next” section on page 27
for information on locating additional hardware
documentation.
Warning
After wiring the DC power supply, remove the tape from the circuit breaker switch handle and
reinstate power by moving the handle of the circuit breaker to the ON position.

Installing Cisco Interface Cards on the Cisco ICS 7750
This section describes how to install Cisco interface cards on the Cisco Integrated Communication
System (ICS) 7750, and contains the following subsections:
•
Preparing to Install Interface Cards on the Cisco ICS 7750, page 21
•
Installing Interface Cards on the Cisco ICS 7750, page 22
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” chapter in the
Cisco ICS 7750 System Description
document.
The MRP has two interface card slots (slot 0, slot 1) and the ASI 81 has one interface card slot (slot 1).
Preparing to Install Interface Cards on the Cisco ICS 7750
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.
Timesaver
To configure digital voice ports correctly, any additional PVDMs must be installed before the interface
card is installed on the MRP or ASI 81 card, or the Cisco ICS 7750 will not be recognized as a voice port.
Tip
To see a list of voice ports on the Cisco ICS 7750, use the Cisco IOS
show running-config
or
show diag
commands.
