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 Interfaces

Use 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 tissue



1-3

l Special compressed gas

l Cotton stick (medical cotton or long fiber cotton)

l Special cleaning roll, used with cleaning solvent listed in the first item

l 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).

Figure 1-1 and Figure 1-2 respectively show the slanting and level optical interfaces.

1.1.3 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 ESDwrist 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 thatthe 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, refer to Figure1-3, , , , and .



1-5

Figure 1-3 Wearing an ESD wrist strap (OptiX OSN 7500)

l Check the validity and functionality of the wrist strap. Its resistance value ranges from 0.75

Mohm to 10 Mohm. If the validity period (usually two years) of the wrist strap expires, orthe resistance value fails to meet requirements, replace the ESD wrist strap.

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

l Wear an ESD wrist strap or antistatic gloves and place the board on an antistatic pad whenreplacing board software or chips. Use antistatic tweezers or extraction tools to replacechips. Do not touch chips, circuits, or pins with bare hands.

l Keep all the boards and components that are to be installed in shielding bags. Place removedboards and components on an antistatic pad or other antistatic materials. Do not use non-antistatic materials such as white foams, common plastic bags, or paper bags to pack boardsor 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 packing materials (such as antistatic boxes and bags) for board in the roomfor future use.

1.1.4 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

4.1 Testing the Spare PartsThe spare parts should be maintained so that they are ready to be used. Thus, the time taken toreplace the parts then can be effectively decreased.

PrerequisiteImportant boards must be available in the inventory center.

Maintenance PeriodYearly


CriteriaThe spare boards and the boards that are used on the network should be the same in BIOS version,SCC software version, board software version, and logic version.

NOTE

A portion of the boards of different PCB versions are mutually compatible. If the PCB versions of the spareparts are different from those of the running boards, consult local Huawei technical support engineers.

Procedure

Step 1 See "Querying the Board Information Report" in the Supporting Task of this product to querythe board information report and record the software version of each board, including thefollowing:l Version of the SCC board, that is, NE software version

l Version of the software of each board, that is, board software version

Step 2 See "Querying the Board Manufacturer Information Report" in the Supporting Task of thisproduct to query the board manufacturing information report and record the bar codes of theboards, types of the optical interfaces, and information of optical modules.

Step 3 Test the spare parts to ensure they are ready for use.

----End

Reference InformationFollow the listed principles to maintain the spare parts.

l Principle for check of spare parts:– Check the version and quality of spare parts periodically.

– The spare boards and the boards used in the network should be the same in BIOS version,SCC software version, board software version, and logic version.




Issue 01 (2009-08-14)

– When the network is to be upgraded, provide the parts in time and upgrade the versionof the running parts.

NOTE

If the board belongs to the multiple ID board, see "Board Version Replacement" for board compatibilityand replacement.

l Principle for storage of parts:– The spare parts must be stored in line with regulations and be kept for exclusive use.

– The spare parts must be stored in shielding bag and no friction should be caused amongthem. These bags with parts inside should be kept in special antistatic cupboard andaway from sundries.

– Wear an antistatic glove to touch the spare parts.

– The inbound/outbound information must be recorded and timely refreshed. Hence, theparts can be supplemented accordingly.
