For information about the LEDs and their activity on the FM-24SFi module, see “I/O Module LEDs” on 
page 176.

The FM-24SFi module requires that you load ExtremeWare version 6.1.7 or later and BootROM 6.5 or 
later on your switch. 

Figure 82 shows the 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 49 
describes the optical specifications for the FM-24MFi module
