Internal 01 August 2006 Classification of Cable Labels Training Course No : EQA LM-002 Composer : Engineering Quality Dept HUAWEI TECHNOLOGIES CO., LTD All rights reserved www.huawei.com Classification of Cable Labels Engineering cable labels are classified into two types respectively for the power cable and signal cable: Label of the signal cable ： Signal cables include the alarm cable, network cable, optical fiber, trunk cable, and user cables (excluding the antenna feeder) Power cables include the DC power cable and AC power cable (excluding the power bus bar) Label of the power cable If the customer needs to ensure the consistency of label description of all devices in the equipment room, the contents of the label must be filled in according to the customer’s requirements This must be specified in the self-check report HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Preparing Cable Labels  You can fill in the contents of the label in two ways: printing or manually writing with the oil pen The printing method is recommended for the efficient and nice looking purpose Print the label 1) Template requirement When printing the label, you must use the printing template You can get the template from one of the following means: a) Download the template from the technical support website at http://support.huawei.com/support/ The path is Knowledge Center/Project Service/Project Quality/Common Qualify Standard and Template b) Get the template from the Huawei representative office The template is prepared by using the Microsoft Word You can adjust the template according to the product installation manual HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Preparing Cable Labels 2) Printer requirement: The laser printer must be used 3) Printer paper sending requirement: Manually send the paper one by one, regardless of the printer model used Automatically send the paper is not recommended, in case the paper is jammed 4) Printed labels must meet the following three requirements: a) All contents are on the label, but not on the liner paper of the label b) Contents in each blank must be centered Printed contents of a single line cannot cover the parting line and the word “TO:” c) If the first item has too many contents and the contents can be printed in several lines by combing several blanks, adjust the position of these contents to prevent them covering the “TO:” that is already on the label Manually write the label (The black oil pen must be used.) HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Attaching Cable Labels Signal cable label The label is attached to the place 2cm away from the connector by default, or on other place in special case Avoid attaching labels on the curve cable or other position that affects the cable installation ： After labels are attached to the cables, all strips with words must face right or downward HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Attaching Cable Labels  Method of attaching the label of signal cable ： HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Attaching Cable Labels ： Attach the label to the power cable ： Remove the label from the liner paper and attach the label in the square groove of the marking plate on the cable tie The cable tie is bound at the place 2cm away from the connector by default, or on other place in special case You need to bind cable ties on both ends of the cable After cables ties are bound on the cable, all marking plates must face right or upward HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Label Contents Label contents of the power cable The power cable label is only attached to the marking plate of the cable tie The contents include the peer end position of the cable, which is started by “TO:” That is, only the position of the peer device, control cabinet, cable distribution box, or socket of the cable is marked Label contents of the signal cable After the signal label is attached, contents on two sides of the label respectively identify the position of the port connected to each end of the cable The port contents must meet the following requirements: The position information of the local end is written in area The position information of the peer end is written in area 2, that is, the area with the mirror writing “TO:” Area will be folded when the label is attached HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Precautions when Using Labels Keep labels clean when writing, printing, or attaching the labels Label paper used is moisture-proof and water-proof Thus, it is prohibited to use the ink jet printer or fountain pen to write the contents in any case Attach labels in a neatly and ordered manner Because the new label is in strip shape, if the attaching position and direction of the strip are not uniformed, the appearance of the product will be seriously affected The power cable must be bound with cable ties with marking plate The cable ties must be bound at the same height and directions of all marking plates must be consistent HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page Engineering Label of External Alarm Cable  The external alarm cable is connected to the first cabinet in each row This cabinet is used for power distribution On this cabinet, the labels must be attached to indicate which device the connecting terminal should be connected to If the equipment side does not have special requirement, engineering labels can be spared In this case, contents are only filled in area HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page 10 Engineering Label of Network Cable  This type of label is applicable to the network cable of the board inserted to the sub rack, or the network cable used to connect various Hubs to the server or agent in the value-added services HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page 11 Engineering Label of Optical Fiber (1)  This type of label is applicable to the optical fiber with the optical connector on the board in the sub rack or chassis device There are two types of optical fiber label The first is used for the optical fiber connecting two devices The second is used for the optical fiber connecting the device and optical distribution frame (ODF) Example of optical fiber label between devices: Example of optical fiber label between the device and ODF: HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page 12 Engineering Label of Optical Fiber (2)  Contents of optical fiber label between devices: HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page 13 Engineering Label of Optical Fiber (3)  Contents of optical fiber label between the device and ODF: HUAWEI TECHNOLOGIES CO., LTD All rights reserved Page 14 Engineer Label of Trunk Cable Between Devices (1)  There are two types of trunk cable label One is used for trunk cable connection between two devices, for example, connection between the trunk board and built-in transmission module, and connection between two trunk boards In this case, the label is attached to each end of the cable, indicating the position of the cable on the device, or the position on each of the two trunk boards of the same device Another type of label is used for connection between a device and the digital distribution frame (DDF) In this case, the label is attached to each end of the cable, indicating the positions of the cable on the device and on the DDF  Trunk cables include 75Ω/120Ω E1 cable, 100Ω T1 cable, 34M/45M/140M/155M cable,
