7750 SR-a Modules
The 7750 SR-a modules are designed for use in the 7750 SR-a4 and 7750 SR-a8 chassis. This
section describes the following modules:
•
•
•
CPM-a
The CPM-a, which is used in the 7750 SR-a4 and 7750 SR-a8, provides:
•
control plane functions and determines the route tables
•
management and console interfaces for system management
•
system synchronization interfaces for external synchronization input and output
signals
•
alarm interface and notifications
The CPM-a does not provide a switch fabric. The IOM-a forwards traffic from the ingress to
the egress ports.
At least one CPM-a must be installed in the 7750 SR-a chassis. The system cannot boot
without a CPM-a installed in the chassis. Two CPM-a cards are required for system
redundancy. The redundant standby (secondary) CPM-a operates in standby mode and takes
over system operation if the active (primary) CPM-a fails. The 7750 SR-a CPM-a is intended
only for the 7750 SR-a chassis and is not interchangeable with other 7750 SR products.
The CPM-a is field-replaceable and hot-swappable. Refer to the 7750 SR OS Basic System
Configuration Guide for information about CPM-a redundancy.
Each CPM-a supports two, Type-II capable compact flash (CF) memory devices:
•
external CF slot—CF slot accessible from the front of the CPM-a card. The slot can
support CF cards up to 32 Gbytes, and can be used to store accounting records, logs,
and TiMOS images.
•
internal CF slot—CF slot accessible on the circuit board when the CPM-a is removed
from the chassis. This slot is used for the CF card that contains the system OS. See
