NOTE

When you install BR-MLX-1GCx24-X modules, you must upgrade the software on all interface modules and management modules to the appropriate software release. For more information on the appropriate software release refer to the Hardware Installation Notes that shipped with the modules.

NOTE

When you are replacing older modules with 24x1G modules, you must first delete the software configuration for the older module. If you do not delete the old configuration, a configuration mismatch will occur when you install the new module. This mismatch will be displayed in the results of the show config command.

NOTE

The SNMP Management Information Base (MIB) uses the Interface Index (ifIndex) to assign a unique value to each port on a module or slot. The number of indexes that can be assigned per module is 20, 40, or 64, depending on the number of ports on the module. When installing 24-port copper or fiber interface modules, you must change the ifIndex allocation to 64 before you install the module, or the module will not operate properly.

Figure 21 shows the front panel of the BR-MLX-1GCx24-X interface module.
