3.1.2.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
3.1.3 Mini-GBIC Slots
These are 4 or 24 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-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 connection interface
• Connection speed: 1 Gigabit per second (Gbps)
To avoid possible eye injury, do not look into an operating fiber-
optic module’s connectors.
3.1.3.1 Transceiver Installation
Use the following steps to install a mini GBIC transceiver (SFP or XFP module).
1 Insert the transceiver into the slot with the exposed section of PCB board facing
down.
