- Nature needs awe
This epidemic is caused by a new type of coronavirus. The new type of coronavirus is a type of microorganism. Each type of microorganism has its own genus group. For example, the genus group of SARS virus is civet cat and bat; the genus group of new type coronavirus is bamboo rat , Pangolins, bats, humans should not catch and eat these animals, and should not keep some wild animals as pets, such as hamsters, squirrels, poultry, and birds. Don’t break the balance between man and nature. , Otherwise it will bring us unnecessary trouble, so we should look at this epidemic with awe.
- Thoughts on the Necessity of Building a Comprehensive Cabling Management System under the Epidemic
Reducing personnel entering and leaving the site and reducing personnel contact is the key to preventing the epidemic. The use of visual integrated wiring management system network system link resource viewing, dynamic tracking, online planning and offline real-time functions can reduce personnel entry and exit and reduce personnel In order to achieve the goal of reducing the epidemic situation and further escalation, it is necessary to build an efficient visual integrated wiring management system.
2.1. The visualization system has strong collaborative office capabilities
Through the visual integrated wiring management system, it has the ability of collaborative office. The collaborative office of the system reflects the aspects of online planning and offline implementation. The system is realized through process management, plan management, document management, asset management, document management, fault location, change management and other functions. IT management staff, link management staff, asset management staff and related operators work together organically. 
2.1.1. Accurate documentation
With the continuous accelerated development of technology, the traditional Excel table recording method can no longer meet the requirements of modern operation and maintenance management. netTerrain visual wiring management software can comprehensively record IT equipment information and link and line information, including IT equipment model, board, port, brand, manager, operator, daily operation record, cable number, port information, After installation time, maintenance records, operating status, shelf life, etc., the physical topology diagram is automatically generated after the information is input.
Accurate management documents can help to make various records and greatly improve the level of refined management.
2.1.2. Asset Management
Information technology (IT) asset management is an important part of the management system. The purpose of asset management is to improve the effective utilization and availability of business assets to reduce operating costs. Assets include all software and hardware elements in the business environment. It usually involves collecting detailed hardware and software inventory information, which is then used to determine the purchase and redistribution of hardware and software. Visual asset management can help organizations manage their IT assets more effectively, avoid unnecessary asset purchases and improve the utilization of existing resources to save time and money. 
2.1.3. Capacity management The 
data center capacity dashboard provides a summary of capacity statistics and four exception charts for rooms according to different standards:
the top 5 rooms calculated by the number
of racks, the top 5 calculated by the utilization rate of the rack unit Chart of rooms [%] Chart
of the top 5 rooms by rack weight utilization [%] Chart of the top 5 rooms
by power utilization [%]
The 4 projects have the following capacity statistics: 
2.1.4. Change management
netTerrain can be used as an advanced tool for change management.
In particular, there are two important functions: document management and work order management.
2.1.4.1. Document Management
NetTerrain document management can control the changes and processes of system documents. Users can use this function to perform processes, configure files, and use other tools to design operations.
2.1.4.2. Work Order Management
Work order management is an important part of operation and maintenance work. Work order issuance, work order execution, work order closure, and work order audit can all be realized through software operation + manual verification combined with authorization management methods. Core operations such as: There are mature management methods for equipment on-rack, off-rack, port connection, jumper connection, wire label management and other operations.
2.1.4.3. Event Management
The three major event management functions include:
1. netTerrain records various alarm events
2. Generates alarms according to predetermined thresholds
3. Alarm notification occurs
2.2. Troubleshoot the integrated wiring system remotely
Combining the information at hand and the information of on-site personnel on duty, take this opportunity to sort out the basic data related to the existing integrated wiring, including:
1. Cabinet information
- Refer to the floor plan of the completed cabinet in the computer room
- If there is no floor plan, draw a plan sketch according to the actual layout of the computer room, and mark the cabinet number
- Without cabinet number, according to TIA-606 standard number
2. Equipment board information (switches, routers, servers, storage, patch panels, PDUs and other equipment)
- Fill in the device board model information according to the actual brand model on the device logo
- Fill in the device location information according to the U position of the actual installation cabinet
- Fill in the board position information according to the actual installed device slot of the board
- Use the original number of the existing equipment board number
- No device board number according to TIA-606 standard number
- For projects with asset serial number management requirements, equipment serial numbers should be collected at the same time
3. Link information
- Refer to the original operation and maintenance wiring data, convert the format and use it directly
- Reference integrated wiring system as-built drawing without wiring operation and maintenance data
- Reference jumper cable labels without as-built drawings
For those without any original basic data, after normal work, you can do the following:
- Jumpers without jumper cable labels and without tying are single-lined and numbered according to the TIA-606 standard
- There are jumpers that can be bundled and disconnected for a short time. With the consent of the management personnel, the line measuring instrument can be used for calibration
- There are jumpers that cannot be broken while strapping, and the original straps need to be removed, and after the single strip is combed, use Velcro to re strap it.
2.3. Remotely carry out the change management of the integrated wiring system
The key to remotely commanding and implementing the change of the integrated wiring system is the correct understanding of the change by the changer and the accuracy of the change. First of all, for remote changes, operation and maintenance managers need to graphically describe the changes, combined with basic data, map the changes through CAD or VISIO, and deliver the change drawings by mail. Or the on-site personnel have the ability to produce drawings, and the on-site staff will produce the drawings, and the management personnel will review them. After the review is passed, the changes can be implemented. Secondly, after the implementation of the change is completed, the implementation personnel need to take photos of the changed link connection points on the spot so that the management personnel can confirm the changes through the photos. Through these two measures, to ensure the accuracy of the change. 
3. Conclusion The
visual line management system can effectively isolate the cross-contact between the system manager and the operator in the computer room management under the epidemic situation, and it can also effectively build the personnel in and out of the computer room, which can effectively block the chance of virus infection. Therefore, it is necessary to build an efficient visual line management system.
