1 Router modules Router modules The following sections describe management modules, interface modules, and switch fabric modules. The figures in the previous sections show the router slots where you install modules and power supplies. For installation instructions for these components, refer to the appropriate installation chapter in this guide for your model. Management modules Table 1 lists the management modules that are available for PowerConnect B-MLXe routers. TABLE 1 Management modules Part number Description NI-MLX-MR PowerConnect B-MLXe management module, 1 GB SDRAM, dual PCMCIA slots, EIA or TIA-232 and 10/100/1000 Ethernet ports for out-of-band management. The management module controls the hardware components, runs the networking protocols, and provides the Real Time Operating System (RTOS). Each router requires one management module, and can accommodate a second module for redundancy. A redundant management module works in conjunction with the active management module. If the active module becomes unavailable, the redundant management module automatically takes over the system operation, minimizing system downtime. For information about the redundancy feature, refer to the "Using a Redundant Management Module" chapter in the PowerConnect B-MLXe Configuration Guide. Management modules are installed in dedicated slots marked M1 and M2. By default, the module installed in slot M1 is the active management module. Management modules are hot-swappable, which means you can remove and replace them without powering down the system. Figure 4 shows the management module front panel.
