FM-24MFi Module
Figure 85 shows the FM-24MFi module.
Figure 85: FM-24MFi module
The FM-24MFi module has 24 100 Mbps Ethernet ports, using standard MT-RJ connectors. The
FM-24MFi module supports 100BASE-FX in multi-mode only.
The default configuration of the FM-24MFi module is as follows. All ports:
• Are added to the default VLAN as untagged.
• Inherit the properties of the default VLAN (protocol type, VLANid, and so forth).
• Operate in 100 Mbps, multi-mode. Half-duplex mode is not supported.
The total optical system budget for the FM-24MFi module is 11 dB. Measure cable plant losses with a
1310 nm light source to verify that your cable plant losses are within the optical budget. Table 55
describes the optical specifications for the FM-24MFi module
.
LEDs
The FM-24MFi module has the following LEDs:
•
Module status
• Port status
For information about the LEDs and their activity on the FM-24MFi module, see “I/O Module LEDs”
