Figure 2-6. Warning! Creating Redundant Paths between Network Devices
Gigabit Ethernet Ports (RJ-45 and GBIC Module Bays)
Your NETGEAR Model GSM712/GSM712F Managed Gigabit Switch has either 1000BASE-T port or as a
GBIC module bay. The default setting for those ports are for the automatic detection of media being used.
Which means depend on which connector is used, the port type will be set automatically. Or they can be
selected via management interface configuration. 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/GSM712F 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.
