The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
• Duplex: Auto

3.1.2 SFP Slo ts
These are slots for Small Form-Factor Pluggable (SFP) transceivers. A transceiver is a single unit that
houses a transmitter and a receiver. Use a transceiver to connect a fiber 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 connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
