ASR 5000 Platform
The following application cards are supported for use in the ASR 5000 chassis:
•
System Management Card (SMC):
The Session Management Card (SMC) is used with the packet
processing cards (PSC2 or PSC3) in the ASR 5000 hardware platform. It serves as the primary controller,
initializes the entire system, and loads the software's configuration image into other cards in the chassis.
Up to two SMCs can be installed in the chassis: one primary and one redundant "hot-standby" card.
Chassis slots 8 and 9 are reserved for the SMC only. By default, when the chassis' power is on, the SMC
in slot 8 is active. The other SMC is automatically placed into standby mode.
Do not place any card other than an SMC into slots 8 or 9 of the ASR 5000. Doing so
will cause damage to the card and possibly the chassis' mid-plane.
Caution
•
Packet Processing Cards:
The packet services cards provide the packet processing and forwarding
capabilities within a system. Each packet processing card type supports multiple contexts, which allows
you to overlap or assign duplicate IP address ranges in different contexts. The minimum recommended
redundancy for packet services cards is one redundant card for up to 13 active cars.
The following table details the specific ASR 5000 chassis slot assignments for each of the above card types.

Packet Processing Cards
To achieve optimal airflow performance in minimum system deployments, populate packet services cards
within the chassis from the middle of the chassis outward. Leave an empty slot between the cards, when
possible. For example, for four PSC2s, use slots 3, 5, 12, and 14. For two PSC2s, use slots 5 and 12. For
more detailed information on SMCs and packet processing card types, refer to the

Important
Packet Processing Card Redundancy
To optimize network efficiency and minimize down time, the system supports 1:n redundancy for packet
processing cards of the same type.
