Power supply requirements for BR-MLX-1GCx24-X interface modules
For power supply requirements for BR-MLX-1GCx24-X interface modules, refer to
routers on page 271.
24-port 1 Gbps fiber interface module
The 24-port 1 Gbps fiber interface module is available in the following formats:
• BR-MLX-1GFx24-X
• BR-MLX-1GFx24-X-ML
The 24-port 1 Gbps fiber interface modules has 32 Mb of flash memory and provide 24 physical ports, through which you can connect
your router to other network routers. BR-MLX-1GFx24-X-ML supports up to 512K IPv4 routes in hardware. BR-MLX-1GFx24-X
supports up to 1M IPv4 routes in hardware. The ML version can be upgraded to a X version through a software license. Please contact
Brocade to purchase the license upgrade.
NOTE
24-port 1 Gbps fiber interface modules support 1 Gbps Copper SFP optics at 10 Mbps, 100Mbps and 1Gbps
speeds.
NOTE
When you install BR-MLX-1GFx24-X and BR-MLX-1GFx24-X-ML 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 when installed.
