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
3.1.2 Dual Personality Interfaces
There are four dual personality interfaces, comprising four 1000Base-T/SFP combo ports. For each
interface you can connect either to the 1000Base-T port or the SFP slot. If an SFP transceiver is
inserted in the SFP slot, the corresponding 1000Base-T port will be disabled.
Dual Personality
Interfaces
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.
SFP Slots
(GS1910-48 and
GS1910-48HP
only)
Use SFP transceivers in these slots for fiber-optic or copper connections to
backbone Ethernet switches.
SFP+ Slots
(XGS1910-24
and XGS1910-48
only)
Use SFP+ transceivers in these slots for fiber-optic connections to backbone
Ethernet switches.
Console Port At the time of writing, this port is reserved for future use, such as firmware
upgrade using an RS-232 cable.
