This can be done by hitting the space bar on the two letters next to the port number. Note: enabling the GBIC connector for a Gigabit Ethernet port disables the built-in 1000BASE-T port. Note: GBIC ports do not support Auto Negotitation. You must manually configure the GBIC port. The default values are 1000 Mbps, full duplex.

There are three `Boot from:' options: Net, Net & Save, and Last Saved. Please refer to Chapter 5 when updating software. Net option: This option allows you to try out a new image before upgrading. It requires a TFTP filename and a server IP address to retrieve the specified image from the given IP address. The new image will not overwrite the one in non-volatile memory. Net & save option This option requires the same setup as the Net option, i. e. However, it copies the image to non-volatile memory directly and then the system boots from non-volatile memory Warning: The previous image in non-volatile memory will be lost when the procedure completes.

Return Loss Return loss measures the amount of reflected signal energy resulting from impedance changes in the cabling link. The nature of 1000BASE-T renders this measurement very important; if too much energy is reflected back on to the receiver, the device does not perform optimally. [. . . ]
