When you insert a cable into the smart switch's RJ-45 port, the smart switch automatically
performs the following actions:
•
Senses whether the cable is a straight-through or crossover cable.
•
Determines whether the link to the attached device requires a normal connection (such
as when you are connecting the port to a computer) or an uplink connection (such as
when you are connecting the port to a router, switch, or hub).
•
Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections while
eliminating concern about whether to use crossover or straight-through cables when you
attach devices.
10GBASE-T Ports
To enable high-speed copper and long distance connections on the smart switch, two RJ-45
10GBASE-T copper ports (the two ports to the left of the SFP+ ports on the front panel)
support speeds of up to 10 Gbps.
You can also use the 10GBASE-T ports to connect the smart switch to a stack.
SFP+ Ports
To enable high-speed fiber and long distance connections on the smart switch, two SFP+
fiber ports (the rightmost two ports on the front panel) accommodate standard 10G and
1G SFP+ transceiver modules, which are sold separately.
You can also use the SFP+ ports to connect the smart switch to a stack.
Reset Button
The smart switch provides a Reset button on the front panel to allow you to manually reboot
the smart switch. This action is equivalent to powering the unit off and back on. The last
saved configuration is loaded into the smart switch as it resets.
To reset the smart switch using the Reset button:
1.
Insert a device such as a straightened paper clip into the opening.
2.
Press the recessed Reset button for a short time (less than two seconds).
The front panel LEDs turn off and light again when the smart switch performs its
power-on self-test (POST).
Factory Defaults Button
The smart switch provides a Factory Defaults button on the front panel so that you can
remove the current configuration and return the device to its factory settings. When you press
the Factory Defaults button, all custom settings including the password, VLAN settings, and
port configurations are returned to default values.
