No matter how reasonable the spare parts quota is, if the parts in the warehouse cannot be used at the critical moment, it means that there are no spare parts. What daily management really needs to focus on are three things: the quantity on the account is consistent with the physical objects in hand, the code writing matches the docking equipment, and the performance of the inventory parts does not drift with the storage time.

Vouchers are retained when entering and exiting the warehouse, and faulty parts are registered separately.

When receiving primary spare parts, four columns must be recorded: location of the faulty equipment, serial number of the replacement part, serial number of the replacement part, executor and date. Do not put the replaced parts directly back into the drawer. Store them separately according to the two categories of diagnosed faults and those to be retested. After returning to the warehouse for testing, you can decide whether to scrap or return to the spare parts pool. After three months of persistence, you can calculate the true failure rate of your site, which is much more accurate than the industry experience value estimate. Consumable items such as jumpers can be pressedLC-LC multimode dual-core jumperCount according to the grid according to the specifications, and make up for any missing items. There is no need to register them one by one.

Coding spare parts are sorted according to equipment and never mixed in boxes.

The same module with different brand codes cannot be interchanged. Once the modules are mixed, they must be retested one by one. It is recommended to partition by switch or equipment model, mark the code version and batch on the grid, and retain the test record number at the time of shipment, so that if a compatibility dispute occurs, the batch can be traced back. In an environment where multiple brands of equipment coexist, you canData center high-speed interconnection solutionBased on model convergence based on port planning, spare parts types and inventory pressure will be significantly reduced.

Regular power-on and storage condition inspection

• A batch of optical modules are selected every quarter and powered on to confirm that they can light up normally and report readings.
• Powered transceivers and racks should be powered on every six months, focusing on capacitor aging and shell temperature rise.
• Check the packaging protection and desiccant status of outdoor and power supply spare parts, and isolate them for testing if they get wet.
• The warehouse should be kept dry and ventilated to avoid poor contact caused by oxidation of the module's golden fingers.

Most of the failures of inventory parts that EB-LINK technical support has seen during return visits are caused by the lack of regular power on. Only by doing these three things solidly can the spare parts pool really come to the rescue at critical moments.
