Figure 77: GM-4Si module
The GM-4Si module has four Gigabit Ethernet ports using standard MT-RJ connectors. The GM-4Si
module supports 1000BASE-SX only.
The default configuration of the GM-4Si 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.
Table 45 describes the optical specifications for the GM-4Si module.
