3.1.1 Ethernet Ports

The Switch has 10GBase-T auto-negotiating, auto-crossover Ethernet ports. In 10/100 Mbps / 1/10 Gbps
Gigabit Ethernet, the speed can be 10 Mbps, 100 Mbps, 1 Gbps or 10 Gbps. The duplex mode can be
full duplex at 100 Mbps and full duplex only at 1000 Mbps.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover
Ethernet cable.
When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-
negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal
on the cable and using half duplex mode. When the Switch's auto-negotiation is turned off, an Ethernet
port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to
make sure that the settings of the peer Ethernet port are the same in order to connect.
3.1.1.1 Default Ethernet Negotiation 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 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 or 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
cable to the Switch. The Switch does not come with transceivers. You must use transceivers that comply
Chapter 3 Hardware Panels
DESCRIPTION
Use SFP+ transceivers in these ports for high-bandwidth backbone connections. You can
also insert an SFP+ Direct Attach Copper (DAC) in the SFP+ slot.
Connect to a computer using an RJ-45 Ethernet cable for local configuration of the Switch.
Only connect this port to your computer (using an RS-232 cable) if you want to configure the
Switch using the command line interface (CLI) through the console port.
If you are locked out from the Switch or configuration changes cause the Switch to behave
abnormally and you do not have a backup configuration file or have not saved Config 1,
Config 2, or Custom Default then you must use the Reset button.
Insert a pin to press the Reset button and release after 6 seconds to have the Switch
automatically reboot and restore the factory default configuration file. You will then have to
make all your configurations again on the Switch.
If you insert a pin to press the Reset button and release before 6 seconds then the Switch will
automatically reboot only without restoring the factory default configuration file.
