signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off,
an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus
requiring you to make sure that the settings of the peer Ethernet port are the same in order to
connect.
3.2.2.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
• Speed: Auto
• Duplex: Auto
• Flow control: Off
• Link Aggregation: Disabled
3.2.2.2 Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so
you may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover
or straight ports, so crossover cables can connect both computers and switches/hubs.
3.2.3 Mini-GBIC Slots
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single
unit that houses a transmitter and a receiver. The Switch does not come with transceivers. You
must use transceivers that comply with the Small Form-factor Pluggable (SFP) Transceiver
MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
• Type: SFP connection interface
• Connection speed:
GS2200-8/8HP: 100 Megabit per second (Mbps) or 1 Gigabit per second (Gbps)
GS2200-24/24P: 1 Gigabit per second (Gbps)
3.2.3.1 Transceiver Installation
Use the following steps to install a mini-GBIC transceiver (SFP module).
1
Insert the transceiver into the slot with the exposed section of PCB board facing down.
2
Press the transceiver firmly until it clicks into place.
3
The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is
functioning properly.
4
Close the transceiver’s latch (latch styles vary).
