Comparison of advantages and disadvantages of single patch panel and double patch panel

The working principle and application analysis of single distribution frame

1. The working principle of the single patch panel mode

1. Set up a group of intelligent patch panels, when a new jumper is inserted into the patch panel, the patch panel senses the connection and reports the update of the connection of the patch panel to the analyzer;

2. Then insert the other end of the jumper into the switch port, the switch senses the connection of the port (the port connection here needs to be connected to a normal working network device at the terminal in advance), and then reports the connection formation to the database and stores it.

2. Characteristics of single patch panel mode and its application in engineering

This mode is different from the principle of the double patch panel. The single patch panel mode actually uses the SNMP function to discover the network connection (the head end and the end end need to be connected to network devices), and then use the implanted intelligent patch panel to connect. The connection state of the entire link is formed by means of points, so that when the network is disconnected, the network disconnection is first detected by the SNMP function, and the administrator can find the specific connection point through the previously determined network link connection and carry out deal with.

The single-distribution frame compared with the dual-distribution frame will save some costs in the patching frame, but after understanding its working principle, we will find that there are many defects in the actual application and maintenance of the single-distribution frame:

1. The analog link in this mode is generated when the jumper is connected. When connecting the jumper, it needs to be in a certain order, for example, insert one end of the patch panel to confirm the connection point, and then insert the switch end to confirm the connection of the link. In this way, when the operator does not insert both ends of a jumper in sequence, a wrong connection state will be formed in the database;

2. Since the discovery of the link mainly relies on the SNMP function, when the function of the switching device is closed or unavailable, the intelligent wiring of the single distribution frame will not be realized;

3. When the link is disconnected, or a device at both ends of the link is disconnected (the switch end is disconnected or the terminal device is disconnected), the intelligent management system cannot confirm which end or which end of the jumper is disconnected. , it will not be able to carry out effective management;

4. When the device is restored after the link is disconnected, the single-configuration link cannot automatically identify the connection status. For example, after disconnecting the jumper on the switch side and inserting another socket, if the jumper is not re-connected in sequence, intelligent management The system will not be able to correctly detect the connection status of the network, so in specific projects, the single patch panel system cannot quickly complete the restoration of the intelligent wiring link, and it still needs to manually pull and plug the jumpers one by one.

For large-scale cabling systems, such as data centers and other cabling environments, the single-distribution frame will have a much greater impact on downtime due to the complexity of the operation.

Therefore, the intelligent management system using a single patch panel is more complicated in actual use than the dual patch panel management system and requires more management processes. In the long-term cable management process, various disconnection and connection states need to be manually confirmed and re-operated at both ends of the jumper, resulting in increased labor costs and increased management complexity, which is not conducive to long-term effective cable management. cable management.

Working principle and application analysis of double distribution frame

1. The working principle of the double patch panel mode

1. Apply two sets of intelligent distribution frames in the wiring cabinet, and set up the analyzer, and collect the connection information on the two sets of intelligent distribution frames by connecting the I/O transmission cable of the analyzer to the intelligent distribution frame;

2. One group of intelligent patch panels is used as a switch mapping patch panel, and the port of the switch is extended to this group of patch panels;

3. Another group of intelligent distribution frames is used as a horizontal mapping distribution frame, and the horizontal link is connected to the back-end module of this group of distribution frames;

4. After connecting two sets of intelligent patch panels with intelligent jumpers, the connection information of the intelligent patch panels can be detected through the analyzer, and the connection status of the entire link can be detected by combining with the SNMP function.

Second, the characteristics of the dual distribution frame mode and its application in engineering

In the management of the dual-intelligent patch panel system, the user can monitor the physical connection of the patch panel through the analyzer in real-time, and the monitoring process can be completed without any network connection, or Say it is independent of the network.

1. Such an intelligent management system will not have any impact on network transmission, including transmission speed and information security. And no matter what the network status is, the structure of the double patch panel can effectively manage the intelligent jumper part.

2. The dual intelligent distribution frame cooperates with the SNMP function on the server, which can perform effective and reliable intelligent management of the entire link from: switch - switch distribution frame - horizontal distribution frame - work area panel - terminal equipment.

3. In addition, extending the port of the switch is not only the requirement of the intelligent cabling system for the dual distribution frame, but many applications of high-density switch ports or environments that want to physically isolate the management of jumpers from active devices for better management. Jumper, avoid operation on dense switch ports, also extend switch ports to patch panels, and perform patching and management work between switch patch panels and horizontal patch panels. This reduces network failures due to high port density and improper operation.

Therefore, the mode of the dual distribution frame can not only provide a reliable management method for the intelligent wiring system, but also improve the ability of the wiring system to move, increase and change in the management and maintenance process.

In the case of dual-matching, basically more than 90% of the work is automatically completed by the system, including daily work, including some accidents, and some accidental repairs are automatically identified by the system. If the single-matching method is used, the 50% of the work, after the person arrives at the site to complete the work, the person has to go back to the software platform to do a manual revision. Compared with the double allocation, the workload of the single allocation will increase.

To sum up, for practical engineering applications, the dual distribution frame mode can achieve real physical layer connection management by detecting the connection status of the physical loop and cooperate with the SNMP function, which really simplifies the management of the integrated wiring system, and provides a comprehensive solution for the integrated wiring system. Future moves, additions and changes to the cabling system provide strong support.
