G1-G2 — The switch is equipped with two autosensing gigabit Ethernet

network ports, which use RJ-45 connectors. The gigabit Ethernet ports

support network speeds of 10 Mbps, 100 Mbps, or 1000 Mbps. They can

operate in half- and full-duplex modes. Auto-sensing technology enables

each port to automatically detect the speed of the device connected to it

(10 Mbps, 100 Mbps, or 1000 Mbps), and adjust its speed and duplex

accordingly.

To establish a gigabit Ethernet connection using a miniGBIC port, you must

install a MGBT1, MGBSX1, or MGBLH1 gigabit expansion module and use

Category 5e cabling or fiber optic cabling. To establish a Fast Ethernet

connection using a miniGBIC port, you must install a MFEFX1 (100BASEFX)

or MFELX1 (100BASE-LX) 100SFP transceiver and use fiber optic

cabling.

NOTE On the SLM248G, SLM248P, SLM224G, and SLM224P switches,

miniGBIC ports are shared with standard ports. If a miniGBIC

port is used, the shared standard port on the switch cannot be

used. The following table defines the shared port mapping of the

switch.

Returning the Switch to the Factory Default

Settings

The Factory Default window allows network managers to reset the switch

to the factory defaults shipped with the switch. Restoring factory defaults

erases the configuration file. This should only be performed as a last

resort.

Restoring the factory defaults will erase all of your current configuration

settings. Before you restore the factory defaults, you can save a backup of

your current configuration settings from the Save Configuration window.

You can also restore the factory defaults of your switch by pressing and

holding the Reset button on the front of the switch for more than ten

seconds.
