Figure 1-7. Backup Concentrator Configuration
Hot Swapping of Media Modules
Media modules can be added, removed, and reconfigured without
powering down the ONline System Concentrator or affecting the rest of
the network. This means that you can add entire new segments or make
minor system adjustments during normal working hours without
interrupting the entire system.
