OS9600-OS9700-CMM OS9600/OS9700-CMM

Features:

• Central Control Interface Between External Management Systems and the OmniSwitch 9000 Chassis Backplane
• Integrates System Management Services with Active Switch Fabric Functionality
• Works in Conjunction with OS9600/OS9700 Series Chassis and Network Interface Modules

The OS9600-OS9700-CMM serves as the Chassis Management Module for Alcatel OmniSwitch 9000 Series switches, providing essential system services and switch fabric support to all modules within the chassis. It establishes management connectivity through Console, USB, and Ethernet Management Port (EMP) interfaces, while hosting the Command Line Interface (CLI), WebView web-based management, and software/configuration management functions. The OS9600/OS9700-CMM continuously handles power distribution, chassis temperature monitoring, and switch diagnostics across the system. Data passing from one Network Interface (NI) module to another passes through the CMM fabric; when two CMMs are installed, both fabrics are normally active, delivering active-active redundancy for the switching plane.

The OS9600-OS9700-CMM provides core management functions essential to the entire chassis and is a critical component of the control and monitoring path, directly affecting the proper, normal operation of the overall switch system. One OS9600/OS9700-CMM is required per OS9600 chassis and is installed in the dedicated CMM slot. The OS9600 contains only one CMM slot, so CMM redundancy is not supported on this chassis. The OS9700 and OS9800 chassis support redundant CMM configurations with modules installed in Slot A and Slot B. The OS9600/OS9700-CMM occupies the CMM slots, which run horizontally on the OS9600 chassis and vertically on the OS9700 chassis, located near the center of the chassis. Note that OS9600/OS9700-CMMs and OS9800-CMMs are not interchangeable between chassis types due to physical dimension differences.

For redundant CMM applications on OS9700 and OS9800 platforms, a second OS9600/OS9700-CMM is required in the redundant slot. In addition to standard single-module operation, the redundant configuration performs automatic failover. Using this method, the secondary CMM continually synchronizes with the primary module. If the system detects that the primary OS9600/OS9700-CMM has failed or gone offline, it automatically transfers system control and fabric management to the secondary module through the Smart Continuous Switching process. During this failover, NI modules continue data transmission and Layer 2 forwarding for known routes, maintaining network traffic flow. The OS9600/OS9700-CMM also controls software rollback through its resilient /flash/working and /flash/certified directory structure, allowing the system to return to a prior last known good software version if needed.
