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 9 to 12 are Ethernet ports paired with Ports 9 to 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. The other
Ethernet and fiber ports 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
These are slots for Small Form-Factor Pluggable (SFP) or SFP+ modules, such as an SFP/SFP+
transceiver. The SFP+ (SFP Plus) is an enhanced version of the 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 or SFP+ connection interface
Connection speed: 1 or 10 Gigabit per second (Gbps)
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
3.1.2.1 Transceiver Installation
Use the following steps to install a transceiver.
1 Insert the transceiver into the slot with the exposed section of PCB board facing down.
