1000Mbps (1Gbps) full-duplex mode.
Auto-10G / Full-Duplex
supports Ethernet connections at
100Mbps, 1000Mbps or 10Gbps full-duplex mode and 10Gbps only for fiber connections.
When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to
determine the connection speed. If the peer Ethernet port does not support auto-negotiation or
turns off this feature, the Switch determines the connection speed by detecting the signal on the
cable. When the Switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured
speed 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.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
Ports 11 and 12 are Ethernet ports paired with Ports 11 and 12 SGP/SFP+ (fiber) slots. The Switch
uses one of either the Ethernet or fiber connection with the fiber connection having priority if the
corresponding Ethernet port is also connected. This means that if Port 11 fiber slot and Port 11
Ethernet port are connected at the same time, then Ethernet port 11 will be disabled. Ethernet and
fiber ports 12 work the same way.
3.1.1.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
• Duplex: Full
• Flow control: Off
• Link Aggregation: Disabled
3.1.2 SFP

SFP+ Slots
Fiber ports 11 and 12 are slots for Small Form-Factor Pluggable (Plus) modules, such as an SFP or
SFP+ transceivers. SFP+ is an enhanced version of SFP and supports data rates of 10 Gbps. A
transceiver is a single unit that houses a transmitter and a receiver. Use a transceiver to connect a
fiber-optic cable to the Switch. 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 connectors.
• Type: SFP/SFP+ connection interface
• Connection speed: 1 or 10 Gigabit per second (Gbps)
3.1.2.1 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.
