TIA/EIA 568a and 568b Wiring Color Codes

TIA/EIA-568-B.1-2001 is likely the most commonly used and talked about feature of the specification created in 1988. 568-a is the definition of pin assignments for the the pairs within Category 3 (CAT3), Category 5 (CAT5) and Category 6 (CAT6) unshielded twisted-pair (UTP) cables (eight conductor, 100-ohm balanced twisted pair cabling). The Pin/Pair assignments were named T568A and T568b, both of which define the pinout or specific order the UTP pairs need to be terminated within 8P8C (Eight Position, Eight Conductor) modular connecters, also known as RJ45 connectors.

How to enter the BIOS or CMOS setup?

Because of the wide variety of computer and BIOS manufacturers over the evolution of computers, there are numerous ways to enter the BIOS or CMOS Setup. Below is a listing of most of these methods, as well as other recommendations for entering the BIOS setup. ⚠ Note: Apple, or Mac, computers do not have a BIOS and instead utilize an EFI, which does not need to modified based on the hardware in the computer, like a BIOS. The EFI provides better integration between hardware and software for Apple computers, virtually eliminating the need for a BIOS. ⚠ Note: This document does not help if you cannot enter the CMOS setup with password. New computers Computers manufactured in the last few years allow you to enter the BIOS setup using one of the five keys shown below during the boot process. ⇾ F1 ⇾ F2 * ⇾ F10 ** ⇾ DEL ⇾ ESC * If pressing F2 opens a diagnostics tool, your setup key is likely F10 ** F10 is also used for the boot menu. If F10 opens a boot menu, your
