There are two Gigabit Ethernet ports. The speed of the Gigabit Ethernet ports can be 10 Mbps,
100Mbps or 1000Mbps and the duplex mode can be half duplex (at 100 Mbps) or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (100/
1000Mpbs) and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or
crossover Ethernet cable.
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
3.1.2 Mini-GBIC Slots
There are two mini-GBIC (Gigabit Interface Converter) slots for mini-GBIC transceivers. A
transceiver is a single unit that houses a transmitter and a receiver. The switch does not come
with transceivers. You must use transceivers that comply with the 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.
3.1.2.1 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.
