3.1.2 1000Base-T Ports
The Switch has 24 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 100/1000
Mbps Gigabit Ethernet, the speed can be 100 Mbps or 1000 Mbps. The duplex mode can be
both half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (100/1000
Mbps) 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.
3.1.2.1 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 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)
1 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.
