Acadia Management Module

The Management Module is responsible for learning addresses and managing the address cache, as well as protocol management and switch management.

Hardware Features
• PowerPC 750 (RISC) processor
• Memory: 4 MB Flash, 256 MB DRAM, 128 KB NVRAM, 512 KB cache
• Real-time clock
• Out-of-band console: 10/100BASE-T and RS-232
• Dot matrix display
• System management functions and interfaces
• 1.5 million packets per second of hardware-based routing for packets that arrive on layer 2-only media modules

Redundant Management Module
The redundant Management Module is an auxiliary (standby) Module that acts as a fault-tolerant Management Module in the event that the active Management Module fails. The redundant Management Module provides a seamless solution to switch failure. Once the redundant Module is installed, loaded with the same software version as the active Management Module, and synchronized, it is ready to act as a backup to the active Management Module. If the active Management Module does fail, the redundant module quickly assumes control with the least possible effect on network operation. No user intervention is required for the CPU module switchover. The management view is accessible without changing IP or MAC addresses.
