Figure 102: GM-4Xi module
The GM-4Xi module has four GBIC-based Gigabit Ethernet ports. All Gigabit Ethernet ports on this
module use standard GBIC connectors and support 1000BASE-SX, 1000BASE-LX, and 1000BASE-LX70.
The default configuration of the GM-4Xi 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 autonegotiation mode.

• 1000BASE-SX
• 1000BASE-LX
• 1000BASE-LX70

• UTP GBIC
For information about the media types and associated maximum distances for each GBIC type, see

An Alpine 3800 switch populated with GM-4Xi modules supports the following GBIC configurations:
• Install a maximum of three LX100 GBICs per GM-4Xi module; the fourth GBIC slot must remain
empty
• Install two or fewer LX100 GBICs per GM-4Xi module and leave the remaining GBIC slots empty
• Install two or fewer LX100 GBICs per GM-4Xi module and install any combination of the following
GBICs in the empty slots:
