A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of ZyXEL Communications ES-2108, 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 ZyXEL Communications ES-2108 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 ZyXEL Communications ES-2108. 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 ZyXEL Communications ES-2108 should contain:
- informations concerning technical data of ZyXEL Communications ES-2108
- name of the manufacturer and a year of construction of the ZyXEL Communications ES-2108 item
- rules of operation, control and maintenance of the ZyXEL Communications ES-2108 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 ZyXEL Communications ES-2108 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 ZyXEL Communications ES-2108, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the ZyXEL Communications 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 ZyXEL Communications ES-2108.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the ZyXEL Communications ES-2108 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.

The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (ei ght bits), wri tten in dotted decimal notation, for example, [...]

    ES-2108/ES-2108-G User’s Gu ide 206 IP Subnetting Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a valu e of 0 to 127. Similarly the first octet of a class “B” must begi n with “10”, therefore the first octet of a class “B” address has a valid range of 12[...]

    ES-2108/ES- 2108-G Use r’s Guide IP Subnetting 207 Since the mask is always a continuous number of ones begin ning from the left, followe d by a continuous number of zeros for the remainder of the 32 bit mask, you can si mply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” foll[...]

    ES-2108/ES-2108-G User’s Gu ide 208 IP Subnetting Note: In the following chart s, shaded/bolded last octet bit values indicate host ID bit s “borrowed” to form network ID bit s. The number of “borrowed” host ID bits determines the number of sub nets y ou can have. The remaining number of host ID bits (af ter “borrowing”) det ermines t[...]

    ES-2108/ES- 2108-G Use r’s Guide IP Subnetting 209 Example: Four Subnet s The above exampl e illustrated using a 25-bit subne t mas k to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00 , 01, 10 a[...]

For class “A” and class “B” addresses the subnet ma sk also determines which bits are part of the network number and which are part of the host ID. A class “B” address has two host ID octets ava ilable for subnetting and a class “A” ad[...]
