...Switch Configuration Switch Configuration First I would unpack the switch along with all of its contents, check for any missing or damaged items and if any our found I would then contact the cisco team but if everything looks great I would then proceed. If I have all the equipment ready for the switch I would then continue on with what they call the express set up. First thing I would do is verify that no devices are connected to the switch when first initializing the setup the switch will start acting like a DHCP server. Since my network has a static IP address I will change it for the time being to DHCP. Once switch is mounted and I have all my devices prepared for it I will then power it on. As the POST initializes I can get a good indication that the switch is functioning properly. I can tell when the POST is complete by SYSLED blinking green and if it fails it would blink an amber color. Next with my laptop I will hook directly in to the switch via CAT5. From there I will log in to the switch by opening my web browser and in the address bar typing in the IP address of the switch, which by default is 10.0.0.1 then you will enter the express setup GUI will open. In the express setup GUI I will configure my VLAN ID, IP, and IP subnet mask then I will enter my routers IP to point the switch through my default gateway. Then I will enable Telnet and set the Telnet password this will allow me to access and manage my switch using the command line interface (CLI). I can...

...| Switch Configuration | | | Amanda Robertson | 4/20/2014 | | I was Hired By a company as a network engineer. One of my first jobs was to purchase, install, configure and deploy a Cisco Catalyst 2960-S Series Switches. This is a popular choice with the LAN Base Software, which comes with the switches. I found that this switch would be compatible with the companies needs having 48 ports, POE configurations that offer up to 15.4w per port, USB storage, 10 GB Ethernet uplink flexibility. This switch would use either copper or fiber optic cabling however I would prefer the fiber optic. The first step that I would have to take is to connect all hardware properly. “When you first set up the switch, you should use Express Setup to enter the initial IP information. This enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration” (Cisco, 2006-2010). Plug in the AC adaptor cord to the Cisco switch to power it on. The switch will go through POST and then verify that the SYST LED light blinks green rapidly. To run Express Set up mode, hold the mode button for 3 seconds, or when all lights above mode buttons turns green. Connect a CAT5 Ethernet cable to the switch and computer, after 30 seconds launch a browser and enter the IP address 10.0.0.1 in the browser and press enter. I would then fill out all the information requested by the Express Set up Mode, the Management interface would...

...Theoretical Background A.R.A (Attendance and Room Automation), as the title suggest, this project is about automation. In applying creating this project we, the proponents, aim to integrate multiple devices to produce a system that would automate a room as well as attendance checking. But what is automation? According to Merriam-Webster dictionary, automation is “the technique of making an apparatus, a process, or a system operates automatically. The theory of automation states that “there are three building blocks of automation (1) a source of power to perform action, (2) feedback controls, and (3) machine programming.” (http://www.britannica.com/EBchecked/topic/44912/automation/24840/Modern-developments#toc24841) Power source, being a self-running device, it is necessary for it to have its own power source. The feedback control is the sensing part of the system; this will be the one that gathers the input to be processed delivers the output and will run the actuating device. Last would be the machine programming, provided by the proponents for the whole system to run. Theoretical Framework Each of the devices is supported by different theories which we hope we would be able to integrate. A microcontroller “is a small computer on a single IC containing a processor core, memory, and a programmable Input/Output peripheral.” (http://en.wikipedia.org/wiki/Microcontroller) We will be using this device as the brain of the system. We will be using the memory of the IC to encode...

...in India, we use a manual switch to turn the motor ON/OFF which is used to fill the overhead tank. In such cases the switch is turned OFF only after water starts to overflow from the tank. This in most of the cases leads to a lot of water wastage since the water that overflows, flows into the drains. To overcome the issue of water overflowing from the overhead tank, a device can be installed. This device would buzz when the water in the overhead tank is about to overflow, giving the residents enough time to turn the switch OFF. Hence saving lot of water. The device is also capable of displaying the amount of water in the overhead tank through various LED’s. Approach to the Problem: The main requirements of the water level indicator are: • Low power consumption • Simplified result • Compact • Economical The recommended solution to the given issues: • Use of LED’s enables low power consumption and economical • Use of multiple LED’s gives a simplified result • Use of single IC makes the computation less complex Literature Survey IC 4066 The 4066 is a Quad Bilateral Switch that can be used with digital or analog signals.

...like other animals. The physical characteristics that humans have separate them from other known mammals. Therefore, innovative approach by means or through application of science and technology close the gap that exists between other animals and humans. With that being said, science is a machine that makes life easier to all humans on the planet. It is not surprising to witness humans looking for answers and solutions to all sorts of problem. This is so because humans are fond of using science to make discoveries. As normal as the life itself, the fact that light did not come on is not unusual because light switches sometime malfunction. In a case like the one described above, a person would be more likely to approach a different light switch somewhere in the dwelling and test whether it will work or not. In everyday life, people do not expect things to refer themselves because they were made by humans and their durability depends on how they are use. In many cases, light...

...Which component is better between a Hub and a Switch? A very broad question that can be answered by asking and answering questions like: Will a hub support more bandwidth with multiple pc’s or will a switch? How many connections can each have at a time and can they be stacked? Which is more cost effective? Without these questions you cannot honestly answer the main question. When it comes to bandwidth allocations and how they are supported the switch is generally hands down the better choice. While hubs do support the same amount of bandwidth they share it between machines while a switch dedicates full bandwidth to each machine. To explain hubs better let’s say I have computers A, B, & C. I am on the 'A' computer and wish to send a file to the 'B' computer. C will hear all the talking but will not take action into receiving the file. Each piece of network data that C receives must be inspected by C and after C realizes that it is not for it the data is ignored. So the total bandwidth is shared among the computers. Whatever bandwidth A and B are not using for this file transfer is left for C to use. To sum it up hubs distribute all of the data they receive to all the network devices they are connected to. This is a highly inefficient use of your network bandwidth. However, there is no processing delay created by the hub because the hub, by definition, does no processing. A switch can be considered a 'smart' hub. It will actively look at the traffic it receives and based...

In order to make a clap switch, we have to combine the touch sensor(monostable mode of 555 and the transistorized dark sensor circuits. Whenever there is loud sound produced near the electret condenser mic, pin 2 of 555 gets triggered and it switches on the LED D1. The LED remains on for a definite time determined by R1 and C1. We can adjust the sensitivity of the circuit using a variable resistor in place of fixed resistor R5.
