How to Recover/Reset Password on Cisco 3925

The Cisco 3925 router is part of a family of networking equipment produced by Cisco, which has been a network equipment giant for many years. Used 3925 routers are available on the Internet at reasonable prices, so acquiring one is not difficult. However, if the password is unknown or lost, reconfiguration is impossible until the password is reset or recovered. Cisco has built in a procedure for rescuing lost or forgotten passwords or entering new passwords.

Instructions

1. Connect your computer to the router with the blue serial-to-RJ-45 cable that came with the router. The 9-pin D-shell end connects to your computer's serial port, while the RJ-45 end connects to the console jack on the router. The RJ-45 end resembles a slightly larger telephone jack connector.

2. Turn on your computer and establish a terminal session to the 3925. You can use any terminal emulator, and many are freely available on the Internet. Configure the session settings as follows:

9600 baud

8 data bits

No parity

1 stop bit

No flow control

Plug the router's power cable into an electrical outlet, and as the cisco 3925 router boots, you should see the Cisco boot messages. If you don't see any output on your computer's terminal session, check your settings on the session and restart it if necessary. Press "Break" within 30 seconds of powering on the router to enter rommon (rom monitor) mode.

3. Type "confreg 0x2142" and press "Enter" at the "rommon 1>" prompt. This will cause the router to boot from its internal flash memory without loading the configuration into memory. At the following "rommon 2>" prompt, type "reset" and press "Enter." This will cause the router to reload and ignore the previously saved configuration file.

4. Respond "no" and press "Enter" when prompted for responses to enter the initial dialog or basic management setup. Type "enable" and press "Enter" at the following "Router>" prompt. This will put you into enable mode and display the "Router#" prompts. Copy the non-volatile memory into memory with the "copy startup-config running-config" command, followed by the "Enter" key. Type "sho run" at the prompt and press "Enter" to display the current configuration, including the passwords, some of which may be encrypted.

5. Type "config t" at the prompt and press "Enter." At the "Router(config)#" prompt, type "enable secret <pswd>" -- where "pswd" is the password -- and press "Enter." At this point, your enable password is reset. Press "Ctrl" + "z" to return to the "Router#" prompt.

6. Type "config t" at the "Router#" prompts and presses "Enter." At the "Router(config)#" prompt, type "config-register 0x02102" and press "Enter" to reset the boot register to its normal setting. Press "Ctrl" + "z" to leave configuration mode. Type "copy running-config startup-config" and press "Enter" to save your changes. Reboot the router and you should be able to login with your password.

What Hardware You Need to Use in a Network

Computers connected together in a refurbished cisco equipment are the most important element it contains. PCs can run software that makes them routers, gateways, proxies or file servers. Networks, however, also use dedicated hardware devices in specialized configurations with dedicated software. Hardware elements range from very simple splitters to complicated machines that calculate routes for data sent and received across the globe.

Network Adapter

Every device connected to a network must have a network adapter. Part of the function of the network adapter makes it a Media Access Controller. It must listen for silence on the cable before sending a signal, as well as deal with collision of data. Wired network adapters must conform with the requirements of the physical cable. The most common standard for network cable is Ethernet. Local Area Networks (LANs) operate with media access control (MAC) addressing. Every network adapter has a unique serial number which is also used to provide the MAC address. Wireless cisco refurbished adapters operate in the same manner as a regular network adapter, except they have a radio transmitter/receiver instead of a cable socket.

Cable/Cisco Cable

Despite the consumer popularity of wireless networks, most networks in the world are connected by cable. The most common standard for network cable is the Ethernet standard was originally created by Xerox but is not managed by the Institute of Electrical and Electronics Engineers. buy network hardware The IEEE defines a variety of standards with different types of media including fiber optic and unshielded twisted pair. UTP is the most common cable type in use in networks.

Hubs and Switches

The simplest device for transferring data from one computer to another over a network is the hub. The hub is a box with an array of sockets. Each socket hosts a cable and each cable leads to a device such as a computer, printer or fax machine. Any message coming in on one of the sockets is copied and sent out on all other sockets. buy used cisco The hub does not use addresses but merely repeats what arrives on a socket. Originally hubs were popular because they were much cheaper than switches. The falling price of switches is now making hubs obsolete, since switches offer greater functionality. The switch is the same as a hub except it only copies incoming data out to the socket it has associated with the MAC address it finds in the header of the incoming data packet.

Bridges

The task of the Medium Access Controller requires it to wait for silence on a cable before sending data. This means that if there are many computers connected to the same cable, each must wait a long time to get a turn sending data packets. buy and sell cisco Segmenting the network reduces this wait time, since each computer only competes with other computers on the same segment. Network segments are connected via bridges, which are simple switches with only two sockets: one for each segment. Bridges record the MAC addresses of the computers on each segment and pass data from one side to the other if the source and destination of the data packets reside on different segments.

Routers

Switches and Bridges deal with MAC addresses, while routers deal with Internet protocol (IP) addresses. The MAC address is like the street address of a house and the IP address is like the telephone number. buy sell cisco The Address Resolution Protocol (ARP) maps between the two addressing systems. The MAC address applies across one link, which is usually enough to get data across a Local Area Network. Routers send data across many links and the overall path is dictated by the IP address.

Wholesale Cisco Network Equipment

For Cisco resellers, wholesaling Cisco network hardware from some Cisco suppliers like Routerswitch.com is a better choice than purchasing single one from retailers.

One of the main reasons for buying wholesale Cisco equipment is that you get to save money. Held at the cost of buying in bulk is less because you can get a bigger discount for network hardware you bought or get the VIP service for wholesale customers.

If you are looking for an effective way to save money without compromising the quality of Cisco network hardware that you buy, wholesale Cisco hardware is a great choice. You know, most buy Cisco suppliers provide wholesale service for clients who want to buy certain CISCO items, offering biggest discount, free shipping, earlier delivery, etc.

Nowadays, due to fast development of internet, and to make shopping more convenient and easier, online store is a smart choice to select used Cisco network hardware you need. Because they list detailed purchasing guide, preferential price and full info of every cisco item, which can help you buy cheaper used Cisco equipment.

All in all, wholesaling used Cisco hardware (such as Cisco routers, especially for business and enterprises, Cisco switches: Catalyst 2960, 3560, 3750, 4500 and 6500, Cisco firewall: Cisco ASA 5500 series) benefit you more, biggest discount, competitive price, VIP service, free shipping, special gift, earlier delivery, etc. all these are only for wholesalers.
