FM-24SFi Module
Figure 84 shows the FM-24SFi module.
Figure 84: FM-24SFi module
The FM-24SFi module has 24 100 Mbps Ethernet ports, using standard MT-RJ connectors. The FM-24SFi
module supports 100BASE-FX in single mode only.
The default configuration of the FM-24SFi 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, single mode. Half-duplex mode is not supported.
The total optical system budget for the FM-24SFi 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 54
describes the optical specifications for the FM-24SFi module
.
LEDs
The FM-24SFi module has the following LEDs:
• Module status
• Port status
For information about the LEDs and their activity on the FM-24SFi module, see “I/O Module LEDs” on
page 183.
