Console Speed In A CISCO Router

Setting the Console Speed In A CISCO Router

To connect via the console to a Cisco device, your terminal emulation program needs to be set to the following specifications.

Baud rate: 9600 bps
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

These are the default settings for both the console and the auxiliary ports.Although the console port defaults to active with 9600 bps, some router models will allow you to increase the console speed to as high as 115200. Increasing the console speed has its advantages.it is useful for those times when you have to upgrade the IOS through the console port.To change the console speed, you simply use the speed command in line configuration mode for console 0. The syntax for the speed command is speed . Options may vary on different models Once you change the console speed, you will no longer have console access through your existing terminal setting. You will have to change the console setting on your terminal emulation program to match
Example:

!
line console 0
speed 115200

POE - Power Over Ethernet

POE - Power Over Ethernet

Many applications benefit from electrical power sent over ethernet cables. This avoids a separate power cord for things like internet phones and wireless access points. Fortunately and unfortunately, there are several ways to do this. Fortunately you have several choices, unfortunately they are not all compatible. Fortunately you are at the right place to sort out the confusion between standards.

PoE basically "injects" power into an ethernet cable at the source, and "picks" off that power at the destination. The power "injector" and "picker" can be external adaptors or can be "embedded" into the devices themselves. Either way, the destination device is completely powered by the ethernet cable, no extension cord or outlets required. Voila, Power-over-Ethernet

There are basically three methods of sending PoE on the ethernet cable

First type of PoE, using "spare" wire pairs. The Unshielded Twisted Pair wiring (UTP) for ethernet has 8 wires, twisted in 4 pairs. Ethernet connects to only two pairs for data, leaving the other two free. Simply using the "spare" pairs is the hands-down most economical and efficient way to do PoE. But, beware of incompatible standards for polarity and voltage, which vary from brand to brand. More info below. Beware also, some other devices, such as ordinary analog phones, may already be using the "spare" pairs in your network. Also, if you plug your laptop or some kind of non-PoE ethernet device into a port energized with PoE, it may or may not harm your devices. All homebrew and many commercial PoE devices use the "spare" pairs in UTP wiring, and it is the absolute fastest and easiest way to adapt a non-PoE device to use PoE.

Second type of PoE, using "data" wires. The IEEE (Institute for Electrical and Electronics Engineers), same folks who standardized Ethernet itself, standardized PoE in June 2003. The IEEE 802.3af standard uses the same "data" pairs as ethernet, leaving the "spare" pairs free. This PoE adds DC power to the data pairs using signal transformers, and pickes off power at the far end the same way. A comprehensive set of technical standards for Power Sourcing Equipment (PSE) and Powered Devices (PD) create an "idiot proof" system protected from shorted wiring, polarity reversal, or accidentally plugging in non-PoE equipment. IEEE 802.3af is technically complex and best implemented with power management chips specially designed for the purpose, supplied by Dallas, Maxim, Linear Technology, Texas Instruments, and others, that are intended to be embedded into the PoE devices themselves. Expect PoE device makers using their own standard to migrate to IEEE 802.3af in the future.

Third type of PoE is a combination of the two. The new IEEE 802.3af standard alternatively allows the "spare" wire pairs to be energized, to be compatible with both types of wiring. You may mix 802.3af with older or homebrew PoE devices, but the result may not be "idiot proof". If your mixed network has only PoE sources that are IEEE 802.3af compliant, your mixed network is pretty safe from damage, but older devices may or may not operate correctly. This mixed PoE allows brands to migrate to the common standard.
