Includes 4 GB RAM, 1internal compact flash drive (2GB), 1 external compact flash slot with included 2GB card,RS-232 serial console port and 10/100/1000 Ethernet port for management.(MR2)MLXe/XMR Gen2 management (X) module for 32-slot systems. Includes 4 GB RAM, 1internal compact flash drive (2GB), 1 external compact flash slot with included 2GB card,RS-232 serial console port and 10/100/1000 Ethernet port for management.The management module controls the hardware components, runs the networking protocols, andprovides the Real Time Operating System (RTOS).Each router requires one management module, and can accommodate a second module forredundancy. A redundant management module works in conjunction with the active managementmodule. If the active module becomes unavailable, the redundant management moduleautomatically takes over the system operation, minimizing system downtime. For information aboutthe redundancy feature, refer to the “Using a Redundant Management Module” chapter in theBrocade MLX Series and Brocade NetIron Family Configuration Guide.Management modules are installed in dedicated slots marked M1 and M2. By default, the moduleinstalled in slot M1 is the active management module.Management modules are hot-swappable, which means you can remove and replace them withoutpowering down the system.NOTEMR and MR2 management modules cannot be mixed in the same chassis.NOTEPrior to installing or replacing the MR2 management module, you must read the HardwareInstallation Notes that shipped with the hardware.NOTEAlthough management modules are designed to be hot-swappable, you must upgrade the softwareon all interface modules and management modules to the appropriate software release beforeinstalling them. For more information on the appropriate software release, refer to the HardwareInstallation Notes that shipped with the management module.Figure 13 shows a management module front panel.FIGURE 13MR management module front panelRX-BI-MRPwrActiveConsole10/100/1000Port 1Port 218 Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide53-1002373-02
