DANGERThe laser beam at the optical interface board or from the fiber may cause injuries to eyes. Donot stare into the optical interface or fiber connector during installation and maintenance ofoptical interface boards or fibers.

Clean the Fiber Connectors and Optical InterfacesUse the special cleaning tools and materials to clean the fiber connectors and optical interfaces.Some common tools and materials are listed as follows.

l Special cleaning solvent (Isoamylol is preferred, propyl alcohol is the next, alcohol andformalin are forbidden.)

l Non-woven lens tissuel Special compressed gasl Cotton stick (medical cotton or long fiber cotton)l Special cleaning roll, used with cleaning solvent listed in the first iteml Magnifier for optical connectors

For details on how to check and clean fibers, refer to "Inspecting and Cleaning the Fiber-OpticalConnectors" in the Supporting Task.

Replace FibersUse filter caps to cap the connectors of the fibers that are not used temporarily.

Connect FibersWhen the optical power is too high, use an attenuator to prevent damage to the optical interface.

l The slanting optical interface can be directly connected to an attenuator, which must beinserted in the IN port, not in the OUT port.

l The level optical interface cannot be directly connected to an attenuator, but can beconnected through the optical distribution frame (ODF).

2.3 ESDESD can damage boards. Some measures such as proper grounding and wearing the ESD wriststrap should be taken to protect the equipment against ESD.

The general rules pertaining to ESD are as follows:

l Check that the equipment is securely grounded according to requirements.l Always wear an ESD wrist strap during the operation.l Before touching a device, a board or an integrated circuit (IC) chip, you must wear an ESD

wrist strap, and properly ground the other end of the ESD wrist strap to prevent staticelectricity in the human body from damaging the static sensitive components. Ensure that


Parts Replacement


Issue 03 (2010-11-30)

the metallic portion of the ESD wrist strap is in contact with the skin and the other end isproperly connected to the grounding connector. If the ESD wrist strap is not available, wearthe antistatic gloves. For the method of how to wear an ESD wrist strap on the OptiX OSN1500A, refer to Figure 2-3. For the method of how to wear an ESD wrist strap on the OptiXOSN 1500B, refer to Figure 2-4.

l Check the validity and functionality of the wrist strap. Its resistance value ranges from 0.75Mohm to 10 Mohm. If the validity period (usually two years) of the wrist strap expires, orthe resistance value fails to meet requirements, use a functioning wrist strap.

l Avoid touching boards with your clothing, because the touching generates static electricitybeyond the protection scope of the wrist strap.

l Wear antistatic gloves and place the board on an antistatic pad when replacing boardsoftware or chips. Use antistatic tweezers or extraction tools to replace chips. Do not touchchips, circuits, or pins with bare hands.

l Keep the boards and other ESD sensitive parts to be installed in antistatic bags. Placeremoved boards and components on an antistatic pad or other antistatic materials. Do notuse non-antistatic materials such as white foams, common plastic bags, or paper bags topack boards or allow them to touch boards.

l Wear an ESD wrist strap when operating the ports of boards because they are also ESD-sensitive. Discharge the static electricity of cables and protective sleeves before connectingthem to the ports.

l Reserve some materials for board installation (such as antistatic boxes and bags) in theroom for future use.

2.4 LaserWhen you install and maintain equipment, follow the safety precautions to prevent personalinjury or equipment damage.

The safety precautions of lasers consists of the following two parts:

l Personal injury

l Equipment damage

Personal Injury

DANGERThe laser beams from fibers or the optical interface on boards cause eye damage. Do not lookdirectly at the optical interfaces or fiber connectors during the installation and maintenance ofboards or fibers.

DANGERIn the case of an optical interface that is in use, use protective caps to cover the optical interfaceand the fiber connector when you remove the fiber from the optical interface to prevent eyedamage.

20.1 BackgroundThe board version replacement function is intended to solve the version compatibility problemof boards and NE software, to achieve smooth board replacement, upgrade, and maintenance,and thus to reduce the operation expenditure.

New ID Board and Old ID BoardIn the case of board version replacement, boards of new versions are new ID boards and thoseof old versions are old ID boards.

NOTEThe new ID boards and old ID boards are specific to the scenarios for replacement. For example, when theN2EFS0 is to replace the N1EFS0, the N2EFS0 is a new ID board while the N1EFS0 is an old ID board; whenthe N4EFS0 is to replace the N2EFS0, however, the N4EFS0 is a new ID board while the N2EFS0 is an old IDboard.

Multiple ID BoardA multiple ID board is a new ID board with multiple board IDs. When a new ID board is toreplace an old ID board, the new ID board works with the board ID as that of the old ID board.When the new ID board does not replace the old ID board, the former works with the board IDof itself.

Board Version ReplacementUsing the board version replacement function, you can replace an old version board with a newversion board. After the replacement, the configuration and service status of the new versionboard are the same as those of the old version board. Only the boards with multiple IDs supportthe board version replacement function.

The board version replacement function is manifested as follows:

l The new version board can be used with the old version NE software.l The new version board can be used with the new version NE software.l The new version board provides the functions of the old version board.

Application Scenariosl Board replacement

The old version board needs to be replaced due to a board fault or other reasons.l Board capacity expansion

The expansion means that a new version board is added into an empty slot in the NE. Inthis case, the corresponding logical board is not yet configured in the NE.– In the case of the old version NE software, the board has a negotiation with the NE

software. After a corresponding logical board supported by the NE software is added,the board starts to work properly. The board may perform an automatic reset before itstarts to work.

– In the case of the new version NE software that supports all board IDs of an insertedboard, the board automatically works as a latest version board. The reason is that, inmost cases, the inserted board starts to work by using the latest board ID. Hence, you

need to query the board name and then add a corresponding logical board so that theboard can work properly. If you want the new version board to use the ID of the oldversion board, you need to wait for the board reset after you add the logical board. Afterthe board reset, the board starts to work by using the ID of the old version board.

l Board ID modificationA multiple ID board works as an ID board or new ID board. Due to change in configuration,the board ID may mismatch the NE software. In this case, modify the board ID of themultiple ID board by deleting the original logical board and then adding a logical boardmatching the NE software.– Certain data boards, such as the N4EFS0 and N2EFS4, automatically match themselves

and then work as the logical boards newly configured.– Other boards need to be manually reset (cold) and, after a period, work as the logical

boards newly configured.
