Router modules
1
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
Brocade MLX Series and Brocade NetIron Family 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.
MR and MR2 management modules cannot be mixed in the same chassis.
Prior to installing or replacing the MR2 management module, you must read the Hardware
Installation Notes that shipped with the hardware.
Although management modules are designed to be hot-swappable, you must upgrade the software
on all interface modules and management modules to the appropriate software release before
installing them. For more information on the appropriate software release, refer to the Hardware
Installation Notes that shipped with the management module.
