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 19 shows the front panel of the BR-MLX-1GFx24-X and BR-MLX-1GFx24-X-ML fiber interface modules.
FIGURE 19 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 top ports, LEDs to the right (pointing
down) support the bottom ports.
24 1 Gbps fiber ports
Table 12 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
