CONNECTOR

DESCRIPTION

 

Dual

Each interface has one 10/100/1000Base-T RJ-45 port and one Small

 

Personality

Form-Factor Pluggable (SFP) slot (also called a mini-GBIC (Gigabit

 

Interfaces

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

Use SFP transceivers in these slots for fiber-optic or copper connections

 

(GS1910-48

to backbone Ethernet switches.

 

and GS1910-

 

 

48HP only)

 

 

 

 

 

SFP+ Slots

Use SFP+ transceivers in these slots for fiber-optic connections to

 

(XGS1910-24

backbone Ethernet switches.

 

and XGS1910-

 

 

48 only)

 

 

 

 

 

Console Port

At the time of writing, this port is reserved for future use, such as

 

 

firmware upgrade using an RS-232 cable.

 

 

 

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
