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.
