Recommended Minimum Chassis Configuration; Installing Application Cards - Cisco ASR 5000 Installation Manual

Application Card Installation
When the system boots up, all packet processing cards enter standby mode, which means that the cards are
available for use but offline. Installed components are made active through the software configuration process.
Cards that are not configured to enter active mode, which brings them online, remain in standby mode as
redundant components. Packet processing cards that normally operate in standby mode do not require line
cards to be installed directly behind them, as these line cards are not used.
In the event of packet processing card failure, tasks are migrated from the active packet processing card to
the standby card. The line card installed behind the packet processing card that was formerly active maintains
the interfaces to the external network equipment. Redundancy Crossbar Cards (RCCs) provide a path for
signalling and data traffic between the line card and the now active packet processing card.

Recommended Minimum Chassis Configuration

The recommended minimum chassis configuration for application cards, including redundancy, is as follows:
Slot Number
8
9
2 and 4 (see Note 1)
2, 3 and 4 (see Note 2)
11 (see Notes 1 and 2)
Notes:
1. Minimum requirement for hardware redundancy.
2. Minimum requirement for hardware + software redundancy, MME service, SGSN service, as well as
combined services on a single platform.
Install additional cards in the remaining chassis slots as required.
If you use the session recovery feature, a minimum of three active packet processing cards and one standby
(redundant) packet processing card are required.

Installing Application Cards

The installation procedure is identical for all application cards. This section provides the instructions for
installing application cards in the chassis.
For additional information about RCCs, refer to Line Card Installation in this guide.
