Admin Tab - Firmware Upgrade
Downloads or uploads Switch firmware files from a TFTP server. The Switch allows the runtime software and
diagnostic boot files to be upgraded. You must specify “Upgrade” to download a new firmware file or “Backup” to
save a firmware file to the server. Select the Upgrade or Backup radio button, then the file type from the drop-
down menu, either Software Image or Boot Code. Enter the IP address of the TFTP server, specify the file name of
the software on the server, and then click
Save Settings
.
Admin Tab - HTTP Upgrade
Download new Switch runtime software from the local web management PC. Enter the file name of the software
or use the Browse button to locate the file on the PC, then click
Save Settings
.

Appendix A: About Gigabit Ethernet and Fiber Optic Cabling

Appendix A: About Gigabit Ethernet and Fiber Optic Cabling
Gigabit Ethernet
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but
it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware
with either fiber optic cabling or copper Category 5e cabling, with fiber optics more suited for network
backbones. As the Gigabit standard gradually integrates into existing networks, current computer applications
will enjoy faster access time for network data, hardware, and Internet connections.
Fiber Optic Cabling
Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber
tubing, fiber optics use photons of light instead of electrons to send and receive data. Although fiber is physically
capable of carrying terabits of data per second, the signaling hardware currently on the market can handle no
more than a few gigabits of data per second.
Fiber cables come with two main connector types. The most commonly used fiber optic cable is multi-mode fiber
cable (MMF), with a 62.5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than
multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light
signals. A fiber connection always require two fiber cables: one transmits data, and the other receives it.
Each fiber optic cable is tipped with a connector that fits into a fiber port on a network adapter, hub, or switch. In
the USA, most cables use a square SC connector that slides and locks into place when plugged into a port or
connected to another cable. In Europe, the round ST connector is more prevalent.
You must use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules with the Linksys Gigabit Switches.
The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors, and the MGBT1 requires a Category 5e
Ethernet cable with an RJ-45 connector.

Appendix B: Windows Help
24-Port 10/100/1000 Gigabit Switch with Webview and PoE
Appendix B: Windows Help
Almost all networking products require Microsoft Windows. Windows is the most used operating system in the
world and comes with many features that help make networking easier. These features can be accessed through
Windows Help and are described in this appendix.
TCP/IP
Before a computer can communicate within a network, TCP/IP must be enabled. TCP/IP is a set of instructions, or
protocol, all PCs follow to communicate over a network. This is true for wireless networks as well. Your PCs will
not be able to utilize wireless networking without having TCP/IP enabled. Windows Help provides complete
instructions on enabling TCP/IP.
Shared Resources
If you wish to share printers, folder, or files over your network, Windows Help provides complete instructions on
utilizing shared resources.
Network Neighborhood/My Network Places
Other PCs on your network will appear under Network Neighborhood or My Network Places (depending upon the
version of Windows you're running). Windows Help provides complete instructions on adding PCs to your
network.

Appendix C: Downloading using Xmodem
Startup Menu Procedures
24-Port 10/100/1000 Gigabit Switch with Webview and PoE
Appendix C: Downloading using Xmodem
Startup Menu Procedures
The Startup menu can be entered when booting the device. There is a two second window of time to enter the
Startup Menu immediately after the POST test. The menu can be accessed directly from a terminal connected to
the console port. The Startup menu procedures can be done using the ASCII terminal or Windows HyperTerminal.
The software download procedure is performed when a new version must be downloaded to replace corrupted
files, update or upgrade the system software. To download software from the Startup menu:
To enter the Startup menu:
1.
Power off your computer and Switch.
2.
Connect the provided null modem cable from the COM port on your computer to the Console port on the
Switch.
3.
Power on your computer and launch HyperTerminal, follow the instructions in
Chapter 4: Using the Console
Interface for Configuration
to configure HyperTerminal to connect to the Switch.
4.
Power on the Switch and watch for the POST done message:
Done All Pass
.
5.
When the POST done message appears, press and hold Ctrl and press the U key to access the Xmodem
interface.
6.
Check that the switch has sufficient flash memory space for the new code file before starting the download.
You can store a maximum of only two runtime and two diagnostic code files in the switch’s flash memory. Use
the [D]elete File command to remove a runtime or diagnostic file.
7.
Press <X> to start to download the new code file. If using Windows HyperTerminal, click the “Transfer”
button, and then click “Send File
....
” Select the XModem Protocol and then use the “Browse” button to select
the required firmware code file from your PC system. The “Xmodem file send” window displays the progress
of the download procedure. Note: The download file must be a valid binary software file from Linksys for the
target switch.
8.
After the file has been downloaded, you are prompted with “Update Image File:” to specify the type of code
file. Press <R> for runtime code, <D> for diagnostic code, or,<L> for loader code.
