A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Intel PCLA2152B, 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 PCLA2152B 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 PCLA2152B. 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 PCLA2152B should contain:
- informations concerning technical data of Intel PCLA2152B
- name of the manufacturer and a year of construction of the Intel PCLA2152B item
- rules of operation, control and maintenance of the Intel PCLA2152B 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 PCLA2152B 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 PCLA2152B, 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 PCLA2152B.

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 PCLA2152B 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.

    2 (Optional) Connecting multiple hubs Connecting hubs running at 100 Mbps to hubs running at 10 Mbps Use an Intel Cascade Cable to connect the hubs. Hubs running at 100 Mbps can talk to each other, and hubs running at 10 Mbps can talk to each other. However, hubs running at 100 Mbps can’t talk to hubs running at 10 Mbps without bridging equipment[...]

    8 Extending the 100 Mbps network topology You can extend the network topology only by connecting hubs to a switch, bridge, or router. You can’t extend the topology by daisy- chaining hubs together. In the example below, the network diameter is extended to 400 meters by connecting the two hub stacks to an Intel Express 10/100 Fast Ethernet Switch.[...]

    9 Extending the 10 Mbps network topology To extend the 10BASE-T network topology, you can attach hubs to a switch or daisy-chain the hubs using TPE cabling. If you attach a stack of hubs to a switch, each stack gets its own 10 Mbps of bandwidth. Attaching hubs to a switch The illustration below shows two stacks of Express 10/100 Stackable Hubs oper[...]

    15 Frequently Asked Questions I have 10 Mbps and 100 Mbps hubs connected with an Intel Cascade Cable. Can they talk to each other? No. All hubs running at 100 Mbps are in one collision domain (or segment) and all hubs running at 10 Mbps are in a separate collision domain. See pages 5-7 for bridging options. Then why would I connect hubs running at [...]
