3.1.1 Ethernet Ports

The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In
10/100/1000 Mbps Gigabit Ethernet, the speed can be 10Mbps, 100 Mbps or 1000
Mbps. The duplex mode can be both half or full duplex at 100 Mbps and full duplex
only at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the
connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-
through or crossover Ethernet cable.
3.1.1.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
• Duplex: Auto
• Flow control: Off
• Dual Personality Interface: Fiber-optic module first

DESCRIPTION
Each interface has one 10/100/1000Base-T RJ-45 port and one Small
Form-Factor Pluggable (SFP) slot (also called a mini-GBIC (Gigabit
Interface Converter) slot), with one port active at a time.
• 10/100/1000Base-T Ports or 10/100/1000Base-T PoE Ports (GS1910-
24HP and GS1910-48HP only):
Connect these ports to high-bandwidth backbone network Ethernet
switches using Category 5/5e/6 1000Base-T Ethernet cables.
Use an 8-wire Ethernet cable for Gigabit connections. Using a 4-wire
Ethernet cable limits your connection to 100 Mbps. Note that the
connection speed also depends on what the Ethernet device at the
other end can support.
• SFP Slots:
Use SFP transceivers in these ports for 1000Base-X fiber-optic
connections to backbone Ethernet switches.
Use SFP transceivers in these slots for fiber-optic or copper connections
to backbone Ethernet switches.
Use SFP+ transceivers in these slots for fiber-optic connections to
backbone Ethernet switches.
At the time of writing, this port is reserved for future use, such as
firmware upgrade using an RS-232 cable.
