The Arduino Ethernet Shield 2 allows an Arduino board to connect to the Internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield 2 supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.
The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top..
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in Arduino 0019). An SD card library is not yet included in the standard Arduino distribution, but the sdfatlib by Bill Greiman works well. See this tutorial from Adafruit Industries for instructions (thanks Limor!).
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot; this is not supported.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won’t work.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you’re not using one of the peripherals in your program, however, you’ll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.
The shield provides a standard RJ45 ethernet jack.
The reset button on the shield resets both the W5100 and the Arduino board.

Registering a patron's laptop for the Ethernet.
Normally it's a quick and easy process, but this was a difficult one, and I had to call my supervisor (Jennifer Church) for help.

We ran Cat 6 ethernet cable throughout our whole house, for a total of 34 connections. A detailed explanation of the process can be found at home.kellbot.com/2012/03/09/wiring-the-house-for-ethernet/
This motherboard had more stuff built in than any I've ever used. TWO ethernet ports, built-in optical digital audio out (for clean music with no ground loop buzz!), SIX on-board SATA harddrive ports (that's 4.5TB if you use 750G drives!), 4 PCI slots, and 2 PCI express slots (1 of which was tiny). It also has eSATA (external SATA) connectors for at least 2 more drives. I also think the heat sink design is pretty neat.
It also has 6-speaker mini-jack output, but since I'm using optical audio I ultimatley wont be using these. (I'm using just one of these outputs now, as the stereo upstiars is my dad's 1970s unit. Must buy real home theatre receiver soon.)
BACKSTORY: So, as mentioned before (in a 10-part series of blog posts), my trusty computer of 9 years, "Storm", died a nasty death. My secondary/kitchen computer "Hell" stepped up to bat and took Storm's place, but I still needed a new computer for our somewhat newly-built upstairs space. So I built Hades, during which I wrote another 5 blog posts. These are the pictures I took while building it.

Two new linking devices from Rockwell Automation provide PlantPAx process automation system users with connectivity to FOUNDATION Fieldbus devices. The Allen-Bradley 1788-EN2FFR and 1788-CN2FFR linking devices provide a direct link from EtherNet/IP or ControlNet networks to the FOUNDATION Fieldbus H1 device-level network, making the integration of FOUNDATION Fieldbus devices intuitive and seamless.

Data information system ethernet cables await further installation during the construction of the new critical access hospital facility of the Uvalde County Hospital Authority at their 140-acre health care campus in Uvalde, Texas on April 9, 2021.
The 163,000 square foot 3-story facility and the campus will meet the need for expanding outpatient and inpatient services, administrative services, and support services now and in the future.
The new facility will operate 25 Med/Surg, Intensive Care Unit, Birthing Postpartum, and Swing Beds; and will greatly exceed the outpatient service platforms of a traditional. The FY 2017 value of U.S. Department of Agriculture, USDA support is in the form of a $58,450,000 direct loan and a $16,550,000 guaranteed loan. USDA funds account for 89.8% of the total value.

A Powered Fiber Cable System incorporates DC power and fiber-based Ethernet connectivity in one cable – it’s everything a customer needs to be able to install Power over Ethernet (PoE) equipment at distances much longer than the PoE standard allows, without having to do any calculations or design work. The Powered Fiber Cable System extends power to a device (Wi-Fi access point, IP camera, or small cell, for example) at a distance of up to two miles. The Powered Fiber Cable System incorporates two innovations: one is a new hybrid cable that combines power (copper) and data connectivity (fiber) in one cable housing, and the other is the use of a small device used with that cable, called the PoE Extender.
Hybrid power/fiber cables have been on the market for a few years, but they are bulky, expensive to terminate, and they require experts to deploy. CommScope’s Powered Fiber Cable System uses cable that is like an FTTH drop cable, and can be accessed in 30 seconds by standard networking technicians without special tools.
The PoE Extender tackles other deployment issues. CommScope engineers incorporated something new in the circuit world – cheap and highly efficient DC-to-DC electrical conversion to automatically eliminate the voltage drop in the system. The Powered Fiber Cable System automatically manages the electrical voltage drop, eliminating the need for electrical calculations. This system innovation makes the cable less expensive and faster to deploy, and the electronic component innovation eliminates design headaches for the customer.

this is cool stuff.
my arduino and ethernet shield can now remotely control my computer based music player.
the config: apache, php, phpMp2, mpd on the linux server. that provides a webserver (apache), the webserver app (phpMp2) and the audio decoder/player (mpd). all formats are supported, mp3, flac and so on.
on the client side, you simply connect to the webserver (apache/php on the linux box) from the arduino and send formated GET requests, like the one shown in the white program edit window. the black run-display window shows the actual dialog, character by character, in requesting that the next song in the playlist be played. all replies are in the 'pound' format that I developed which is just a simple tagged method of getting data quickly.
the arduino parses that 'pound stuff' and displays song name (etc) info to the lcd screen. when the user presses a NEXT or PREVIOUS or PAUSE remote key on the IR keypad, the corresponding html GET request is sent to the server and this causes the song to be paused or played or whatever.
Microchip announced the KSZ8061 single-chip 10BASE-T/100BASE-TX automotive- and industrial-grade Ethernet physical-layer transceiver, which is designed for data communication over low-cost Unshielded Twisted Pair (UTP) cables. It is the first of a new family based on the patented and programmable Quiet-WIRE® enhanced EMC technology, providing reduced line emissions and superior receiver immunity performance. System reliability is also enhanced with Microchip’s proven LinkMD+® advanced cable diagnostics, along with an embedded signal-quality indicator for the dynamic monitoring of link error margins.
