How to Configure the Cisco Catalyst 3560 Series Switches

Cisco 3560 Series, fixed configuration Enterprise class switch with PoE functionality in Fast and Gigabit Ethernet configurations, cisco ws c3560 24 ts s is intended to provide high-performance network switching while reducing power consumption relative to previous Cisco switches for use in corporate networks. It could also be used for environments in branch office.

Catalyst 3560 Cisco Switches support network switching for voice and video data. So you can use the Express Setup utility that ships with Cisco 3560 switches to configure a Cisco 3560, so that it can be attached to the network.

How to Configure ws c3560g 24ts e specs Series? Do the following guide to finish your Cisco 3560 configuration.

Things you'll need: Ethernet cable

1. Disconnect any cables connected to the switch.

2. Power the switch by connecting the AC power cord to the switch power connector and to a grounded AC outlet. This will start the power-on self-test (POST) process on the switch. spec ww c3560g 24ts s The LED lights on the front of the switch will blink during the POST.

3. Wait for the "SYST LED" light on the front of the switch to turn solid green, which indicates that the POST is complete. Press and hold the "Mode" button on the front of the switch for three seconds as soon as the POST is complete. When all LEDs above the "Mode" button are green, release it.

4. Connect one end of a Category 5 Ethernet cable to any Ethernet port on the switch front panel, and the other end to the Ethernet port on your computer. Open a web browser on your computer and type "10.0.0.1" in the Address bar, then press "Enter". This opens the "Express Setup" page and displays the "Network Settings" fields.

5. Enter the switch's IP address in the "IP Address" field.cisco catalyst ws c3560g 24ts s Click the drop-down arrow in the "IP Subnet Mask" field and select an IP Subnet Mask. Enter the IP address of your network's gateway device, such as a router, in the "Default Gateway" field.

6. Type a new password in the "Switch Password" field. The password can be up to 25 alphanumeric characters long, may start with a number, and is case-sensitive. Re-type your password in the "Confirm Switch Password" field.

7. Type a name for the switch in the "Host Name" field. The host name can be up to 31 alphanumeric characters long.

8. Enter date and time information in the "System Date", "System Time" and "Time Zone" fields.

9. Click the "Submit" button. This exits Express Setup mode and completes the setup configuration.

Quick Look: The Cisco 3560 series is an array of fixed configuration and enterprise class switches that are present in configurations like Gigabit Ether net and Fast Ethernet.This series includes Cisco pre-standard Power over Internet and IEEE 802.3af facilities.

IP Phones, Cost, Mobility and Features You Need Know



Advantage
1.       Cost
A primary benefit of Cisco Ip Phone, and a benefit often referenced by IP telephone service providers such as Vonage and Magic Jack, is the reduction of cost for IP telephone customers. Traditional, circuit-based telephone companies have invested billions of dollars over several decades to build out their infrastructure and provide expensive resources dedicated to maintaining voice communications. Because VOIP technology relies on the Internet, rather than an expensive dedicated network, Cisco Phone service providers can charge considerably lower prices than their traditional counterparts.

2.       Mobility
With the introduction of modular plugs in the 1980s, traditional telephones began to allow users to move the devices from place to place with relative ease. If the user moved the phone to a different location, though, the telephone would operate with a different telephone number and, depending on the service provider, cp-7945g enable different features. IP phones, by contrast and according to IP product vendor Cisco, register with a central server regardless of their physical location. For this reason, a user can move an IP phone from location to location, state to state or even to another country while still keeping the same telephone number and set of features.

3.       Features
Traditional telephone services allow basic features such as call waiting, conference calling, and voicemail and caller identification. According to the Federal Communications Commission (FCC), IP phones typically enable all of these features and a number of others not available in the traditional telephone network. 7945g IP phones, for example, can allow a user to place a call on hold and pick it up from anywhere else with an Internet connection, transfer a call to a telephone on another network, ring incoming calls to several telephones on different networks at the same time and even deliver voicemail messages via e-mail. The specific features offered supported by IP phones vary from phone to phone, cp-7945g= and many may require support from the VOIP service provider.

Disadvantage:
1.       Quality of Service
While the Internet-based routing of IP phone calls enables cheap, mobile service, it also moves voice traffic off a dedicated network and onto an ever-changing digital landscape. In the absence of a dedicated set of voice circuits, IP phones typically, according to Cisco, convert voice sounds into data packages, address them to the VOIP switch and send them out across the Internet with no guarantee that they will arrive at their destination. Despite numerous quality of service (QoS) measures implemented by IP phone vendors, used phones VOIP users may occasionally experience a delay in the conversation (latency), poor or robotlike sound quality (jitter) or miss portions of the conversation (packet loss).

2.       Internet Requirement
Despite their high mobility, cisco ip phone price must have access to the Internet to work. Because IP phones rely on the ability to connect to the Internet and send data packets, according to Cisco, users must subscribe to a broadband Internet service to use the devices. According to the FCC, this requirement may represent an additional expense to users who do not already subscribe to an Internet connection.

3.       Electricity
Traditional telephones require a small amount of electricity to operate, according to service provider CenturyLink, used cisco ip phone but they pull that electricity from a special line card in the telephone company central office. As a result, customers can still use a traditional telephone during a power outage. IP phones, according to the FCC, must draw commercial power to perform their functions and may leave customers without telephone service during a power interruption.
