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
3.1.2 SFP/SFP+ Slots
These are four 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.

2 Press the transceiver firmly until it clicks into place.
