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.
Figure 22 shows the front panel of the BR-MLX-1GFx24-X and BR-MLX-1GFx24-X-ML fiber interface
modules.
FIGURE 22 BR-MLX-1GFx24-X and BR-MLX-1GFx24-X-ML fiber interface module front panel
The front panel includes the following features:
• Arrow-shaped LEDs in center horizontal strip for all ports. LEDs to the left support the bottom
ports, LEDs to the right (pointing up) support the top ports.
• 24 1 Gbps fiber ports
Table 17 describes the LEDs for the BR-MLX-1GFx24-X and BR-MLX-1GFx24-X interface modules.
For a list of SFP optics supported for the BR-MLX-1GFx24-X and BR-MLX-1GFx24-X interface
modules, refer to the latest version of the Brocade Optics Family Data Sheet, available online in the
