A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Black Box LE3700A-R2, 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 Black Box LE3700A-R2 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 Black Box LE3700A-R2. 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 Black Box LE3700A-R2 should contain:
- informations concerning technical data of Black Box LE3700A-R2
- name of the manufacturer and a year of construction of the Black Box LE3700A-R2 item
- rules of operation, control and maintenance of the Black Box LE3700A-R2 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 Black Box LE3700A-R2 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 Black Box LE3700A-R2, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Black Box 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 Black Box LE3700A-R2.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Black Box LE3700A-R2 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.

    8 ETHERNET PRINT SER VER 2. Introduction 2.1 Description The Ethernet Print Server (EPS) is a multiprotocol print server. It provides network access to printers for a variety of network protocols and operating systems. It has an AUI port for connection to an external Ethernet transceiver, and an RJ-45 connector for use with 10BASE-T. It provides on[...]

    13 CHAPTER 3: Installation 4. If Sw2 is off, the EPS will print status information to the serial port as it boots. Attach a console device (we recommend using a terminal) to the serial port of the server. The default serial port settings are 9600 baud, 8 bit characters, and no parity. You can also attach the parallel port to a print device at this [...]

    14 ETHERNET PRINT SER VER After the EPS loads the Flash code and the unit is running normally, the OK LED will blink once each 2 seconds. Depending on SW2’s position, the EPS will print a greeting to the serial port when the unit is operational: Ethernet Address: xx-xx-xx-xx-xx-xx IP Address: undefined Lantronix EPS1 Print Server Diagnostics Repo[...]

    15 CHAPTER 3: Installation 3.1 How Do I Know It’ s W orking? If the EPS appears to be working (OK LED is blinking slowly) and the unit is connected to the network, there are various ways to confirm that the unit is visible to network hosts: • If the EPS has an IP address, you can PING it from a TCP/IP host — the EPS should respond correctly.

    16 ETHERNET PRINT SER VER If a terminal is not attached to the serial port, you can still detect a boot error (typically network-related) via the LEDs. If the OK and network LEDs are blinking rapidly (2-3 times per second) in unison, a boot failure occurred. Once the EPS boots and is running normally, the OK LED will blink once every 2 seconds. 3.

    17 CHAPTER 4: Host Configuration 4. Host Configuration Host configuration is broken down by protocol, since none of the procedures are common to any of the protocols. You must enable the protocol on the EPS service before clients will be able to see and use that service. You should be familiar with the protocol and host setup; refer to the document[...]

    31 CHAPTER 5: Protocol Overview 5. Protocol Over view The EPS supports 4 major protocols: NetWare, TCP/IP, AppleTalk (EtherTalk), and LAT. The 4 protocols provide varying support for printing, and each is discussed below. For all 4 protocols: On the EPS, the term “service” denotes a printing resource that another node can access. Services must [...]

You can use hard disks, printers, and other devices as if they were directly attached to the client station. You can assign access rights, passwords, and privileges to prevent [...]

    33 CHAPTER 5: Protocol Overview The EPS provides two major methods of printing via TCP/IP. Berkeley Remote LPR is supported, as is the RTEL software. Both methods provide queueing of jobs on the host if the host is busy with another job. The remote LPR software allows the EPS to look like another host that can spool and print files, and hosts wishi[...]

If you are using the default zone or only one zone, you do not need to configure any information on the EPS. Only AppleTalk routers provide zones, so if you have no router on your network, you will not need a [...]

    35 CHAPTER 5: Protocol Overview LAT is disabled by default on services provided by the EPS. This is because many network managers object to the frequent LAT service announcements. If you desire LAT on these services, you can easily turn it on. You can also configure LAT hosts to connect directly to a physical port on the EPS, eliminating the need f[...]

    36 ETHERNET PRINT SER VER 6. EPS Configuration In many cases, you may not need to configure the EPS to use it as a print server. Using NetWare and AppleTalk is especially simple. To print using LAT and TCP/IP, you may need to follow some of the setup instructions listed below. You can configure the EPS either via a terminal attached to the serial p[...]

    37 CHAPTER 6: EPS Configuration TCP/IP users may want to set a TCP/IP address or gateway host (SET SERVER IPADDRESS or GATEWAY commands). You might need a gateway host if you have routers on your network and wish to print from non-local networks. The EPS will listen for routing packets (RIP, OSPF, etc.) to auto-select a router, but if these packets[...]

    38 ETHERNET PRINT SER VER 6.3 Port Characteristics You can change all port settings via the SET (or DEFINE) PORT commands. Since the ports logout after each print job, you will generally want to use only DEFINE to configure them. You can LOGOUT the port to force the new settings to take effect. There are 4 basic groups of port settings that you can[...]

For example, you might want an AppleTalk service named “LAB_APPLE” and a NetWare service named “NETW_LASER,” both pointing to the serial port on the EPS. Both queues will accept jobs simultaneously, and jobs from both queues will print on the serial port in the order in which the[...]

The NetWare address is the EPS’s hardware address, and the EPS discovers the network by listening to network traffic. The EPS contacts file servers in the same way. You do need to specify a file server to contact to download new EPS sof[...]
