Figure 2 XMG’s Internet Access Application: Ethernet WAN
1.4.1.3 SFP
If you prefer not to use the Ethernet or DSL line, your XMG also provides shared Internet access by
connecting the Small Form-Factor Pluggable (SFP) transceiver. SFP is also known as Fiber Optics
interface. The Gigabit Ethernet (GbE) WAN with SFP is a dual-personality design (GbE + Fiber) which
enables increased bandwidth and extended coverage. The XMG supports multiple VLANs over the SFP
WAN interface for triple play. To connect the SFP port use a Fiber Optic Module, also known as a mini-
GBIC transceiver, to a Switch or Router.
Figure 3 XMG’s Internet Access Application: Ethernet WAN
Note: You can only have Internet access through one of the ports (DSL, Ethernet or SFP) at a
time. Your XMG has WAN priority, and if you connect all ports simultaneously to a
successful internet access, only one WAN port interface will be active. The XMG will
prioritize SFP, then Ethernet, and last DSL.
1.4.2 XMG’s USB Support
The USB port of the XMG is used for file-sharing and media server.
File Sharing
Use the built-in USB 2.0 port to share files on a USB memory stick or a USB hard drive (B). You can connect
one USB hard drive to the XMG at a time. Use FTP to access the files on the USB device.
