A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of Intel 140T, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.
What is an instruction?
The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Intel 140T one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.
Unfortunately, only a few customers devote their time to read an instruction of Intel 140T. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.
What should a perfect user manual contain?
First and foremost, an user manual of Intel 140T should contain:
- informations concerning technical data of Intel 140T
- name of the manufacturer and a year of construction of the Intel 140T item
- rules of operation, control and maintenance of the Intel 140T item
- safety signs and mark certificates which confirm compatibility with appropriate standards
Why don't we read the manuals?
Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Intel 140T alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Intel 140T, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Intel service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of Intel 140T.
Why one should read the manuals?
It is mostly in the manuals where we will find the details concerning construction and possibility of the Intel 140T item, and its use of respective accessory, as well as information concerning all the functions and facilities.
After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

6 Connection Guidelines General • The 140T is capable of autonegotiating port speed and can operate at 10Mbps or 100Mbps per port. The hub matches the highest possible speed of an attached device. • The ports on the 140T hub are half-duplex. The hub cannot connect to a device at full-duplex. • T o prevent a loop in the network, do not connect[...]

7 Daisy-chaining Hubs Normally , to make a hub-to-hub connection you need to use a crossover cable. The daisy-chain port on the 140T hub is wired MDI so you can use a straight-through cable to connect the 140T to an MDI-X port on a hub or switch. When using the daisy-chain port, follow these guidelines: • Only two hubs (ClassII) can be daisy-chai[...]

8 Media Requirements Incorrect cabling is often the cause of network configuration problems. Read the next two pages if you’re unsure of your requirements. 100Base-TX The 100Base-TX Fast Ethernet specification requires that you use CA T 5 UTP cabling to operate at 100Mbps. If you use lower grade cabling (CA T 3 or CA T 4), you may get a connectio[...]

9 However , if the LEDs remain off, you probably have a bad cable. If a cable passes either of these tests, but the network connection is slow , verify that wires 1 & 2 and 3 & 6 on the cable are twisted pairs. Refer to the following diagrams.
