GBIC Module Bays
Y
our NETGEAR Model GSM712 Managed Gigabit Switch has two Gigabit GBIC module ports. The Gigabit Ethernet ports provide a full-duplex
1000 Mbps (1 Gbps) connection that effectively doubles throughput to 2 Gbps.
The GBIC bay accommodates a standard GBIC module, such as the NETGEAR AGM721F GBIC module or the AGM721T GBIC module. The
AGM721F GBIC module has an SC connector that is compatible with the IEEE 802.3z 1000BASE-SX standard, while the AGM721T has an RJ-45
connector and is compliant with the IEEE 802.3ab 1000BASE-T standard.
LED Descriptions
The front panel of the NETGEAR Model GSM712 Managed Gigabit Switch has LEDs that provide a quick and accurate display of port speed,
activity, collisions, and duplex mode. Table 2-1 summarizes the LEDs on the switch and Gigabit Ethernet module.

Port has made a connection at 1000 Mbps for that port.
Port is not operating at 1000 Mbps.
Data transmission is occurring on the port.
No data transmission is occurring on the port.
Port is operating in full-duplex mode.
Port is operating in half-duplex mode.
Collision is occurring.
Note: When Copper GBIC is used at forced speed mode, link and FDX LEDs are “ on” regardless if RJ45 port is connected.
