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.
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.
