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.
