They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A front-mounted hot-swappable NETCONF DCI chassis includes a chassis body 1. The front and back of the chassis body 1 are respectively provided with a front panel 2 and a back panel 3. The left side of the front panel 2 is provided with an independent display slot 4. A hot-swappable display board 9 is installed in the display slot 4. The display board 9 integrates an LCD display 10, function buttons 11 and control circuitry. The display board 9 is electrically connected to the front panel 2 of the chassis via a board-to-board connector 12. The display board 9 supports plugging and unplugging operations while the power is on.

[0024] The LCD screen 10 of the display board 9 displays the local IP address, device alarm level and content, serial numbers of all boards in the local machine, and the local machine's operating status information. The display board 9 controls the page turning and scrolling of the displayed content through the function keys 11.

[0025] Furthermore, this utility model solves the industry problem of lack of intuitive status display and inconvenient maintenance of key display units during on-site operation and maintenance. The main body 1 of the chassis is made of high-strength metal material, ensuring mechanical stability and electromagnetic shielding performance during long-term operation in the data center environment. An independent and standardized display slot 4 is opened on the left side of the front panel 2 of the chassis. This display slot 4 is used to accommodate a dedicated hot-swappable display board 9. The display board 9 integrates an LCD display 10, a microprocessor control unit, a local storage chip, and function buttons 11. The LCD display 10 can clearly display text and simple graphic information in multiple lines. The function buttons 11 allow on-site operation and maintenance personnel to perform interactive operations, such as switching display pages, locking the current alarm information, or entering a specific settings menu. The display board 9 is electrically connected to the main body 1 of the chassis through a highly reliable board-to-board connector 12. Compared with traditional cable connections, this connection method has significant advantages such as low contact resistance, stable signal transmission, long plug-in / plug-out life, and small footprint, which is the physical basis for realizing the hot-swappable function.

[0026] In actual operation, the display board 9 serves as the local human-machine interaction window for the device and undertakes the crucial task of presenting status information. After the device is powered on, the main control module will continuously push a series of key parameters to the display board 9 through the internal data bus, including the management IP address obtained by the device via DHCP or static allocation, real-time monitored alarms at all levels of the device, the electronic tag serial numbers of all inserted boards in the main body of the chassis 1, and the overall health status of the system. Maintenance personnel do not need to carry mobile terminals or log in to the device command line interface via serial or network cables. They only need to observe the LCD display 10 to quickly grasp the core information such as the network location of the device, the current fault focus, and the hardware asset composition within a few seconds. This greatly improves the efficiency of network connectivity confirmation or fault location during the initial commissioning phase of the device.

[0027] When display board 9 experiences intermittent failures due to prolonged operation or requires hardware upgrades, maintenance personnel do not need to power off the entire device or interrupt ongoing data center interconnect services. They can simply wear an anti-static wrist strap, loosen the fixing screws on the display board 9 panel, and smoothly pull it out of the display slot 4. Then, a spare board is inserted until the board-to-board connector 12 is tightly coupled. After tightening the screws, the newly inserted display board 9 will be automatically recognized by the main control system, the driver will be loaded, and it will be re-initialized, restoring all display functions. This process reduces maintenance time from the previously potentially disruptive business window to minutes, greatly enhancing the device's online maintenance capabilities and business continuity assurance level.

[0028] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 A front-mounted display and control hot-swappable NETCONF DCI chassis includes a chassis body 1. The front and back of the chassis body 1 are respectively provided with a chassis front panel 2 and a chassis back panel 3. The chassis front panel 2 is also provided with eight service board slots 5, which support the access of various optical layer and electrical layer service boards.

[0029] The back panel 3 of the chassis has two main control board slots 6 on the left side, three fan board slots 7 in the middle, and two power board slots 8 on the right side. The main control board slots 6, fan board slots 7 and power board slots 8 are connected to the main control board, fan board and power board respectively via board-to-board connectors 12.

[0030] The two main control board slots 6 on the left side of the chassis back panel 3 adopt a 1+1 redundancy design, the two power board slots 8 on the right side of the chassis back panel 3 adopt a power supply redundancy design, supporting the mixed configuration of PSU-AC / HDC and PSU-LDC power modules, and the three fan board slots 7 in the middle of the chassis back panel 3 adopt an N+1 redundancy design.

[0031] The main control board card connected in the main control board card slot 6 supports the NETCONF network management protocol. The main control board card slot 6 provides two RJ45 type NM management interfaces. The NM management interfaces support gigabit and 100 Mbps adaptive speeds and support cascading management through the OSPFv2 protocol, external DCN management network and other devices.

[0032] Furthermore, the DCI chassis of this utility model integrates advanced network management functions and possesses high reliability. Eight service card slots 5 are provided on the right side of the chassis front panel 2, adjacent to the display slot 4. These service card slots 5 are connected to the chassis core via a high-speed backplane, supporting mixed insertion and flexible configuration of various optical and electrical layer service cards. For example, optical transmission unit cards supporting 200G or 400G rates can be inserted to generate and process high-capacity wavelength division multiplexing signals; multi-service electrical layer aggregation cards can also be inserted to aggregate and map accessed 10GE and 100GE client services. This high-density service card slot design enables the chassis to meet the extreme requirements of data center interconnection for transmission capacity and service types. Two main control card slots 6 with a 1+1 redundancy backup design are provided on the left side of the chassis back panel 3. The main control board connected in slot 6 is responsible for the resource scheduling, protocol processing, and service management of the entire system. The firmware of the main control board integrates the NETCONF protocol stack and provides services to the outside world through two RJ45 NM management interfaces provided on slot 6 of the main control board. This allows the network management system SDN controller or network administrator to use the standard NETCONF protocol to configure devices, query status, and subscribe to alarms, realizing the standardization and automation of device management. The NETCONF management mode changes the device operation and maintenance experience. Remote network administrators can write automated scripts or use a graphical interface to batch and accurately configure services for multiple such DCI devices in the network. Its efficiency and accuracy are far higher than traditional manual command line input. At the same time, the SDN controller can continuously subscribe to the device's performance data to achieve fine-grained monitoring of network quality.

[0033] To ensure the absolute reliability of this management core, the dual main control boards work collaboratively in a primary / backup mode. When the primary main control board experiences a hardware failure or software anomaly, the backup main control board can automatically switch to primary mode in a very short time, taking over all management functions and protocol sessions, ensuring uninterrupted management and unaffected business operations. The two power supply card slots 8 on the right side of the chassis back panel 3 support mixed deployment of various power modules such as AC, high-voltage DC, or -48V DC and support 1+1 redundant power supply. The failure of any power supply card will not affect the normal operation of the equipment. The three fan card slots 7 in the middle area of ​​the chassis back panel 3 constitute an N+1 redundant heat dissipation system, which can intelligently adjust the fan speed according to the temperature inside the chassis body 1 and maintain sufficient heat dissipation capacity when a single fan card fails. This comprehensive redundancy design from management and power supply to heat dissipation together forms the high reliability of the equipment.

[0034] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 A front-mounted hot-swappable NETCONF DCI chassis includes a chassis body 1. The front and back of the chassis body 1 are respectively provided with a front panel 2 and a back panel 3. The left side of the front panel 2 is provided with an independent display slot 4. The front panel 2 is also provided with eight service board slots 5. The left side of the back panel 3 is provided with two main control board slots 6. The middle of the back panel 3 is provided with three fan board slots 7. The right side of the back panel 3 is provided with two power supply board slots 8.

[0035] The frame body 1 has a height of 2U. The sides of the frame body 1 are symmetrically equipped with mounting ears 13. The frame body 1 is compatible with 19-inch and 21-inch mounting width racks by replacing the mounting ears 13.

[0036] Furthermore, the main body 1 of the DCI chassis of this utility model adopts a standard 2U height chassis, and its physical dimensions are precisely designed to be 88 mm high, 444 mm wide, and 485 mm deep. This is an optimized size for high-density deployment in a standard 19-inch rack. To enhance its adaptability to various data center environments, the main body 1 can flexibly adapt to 19-inch or some 21-inch deep racks by symmetrically installing replaceable mounting ears 13 on both sides. This provides deployment convenience for data center server rooms of different specifications. The front panel 2 of the main body 1 uses the display board 9 as the visual and interactive center, supplemented by eight service board slots 5, to form a complete front-end operation interface. Maintenance personnel can perform service board insertion and removal, status observation, and local interaction here. The rear panel 3 of the chassis concentrates the main control board slot 6, fan board slot 7, and power supply board slot 8. This front-to-back separation and functional partitioning layout makes the placement inside the rack orderly and is conducive to the isolation of hot and cold aisles and the smooth flow of heat dissipation airflow in the data center.

[0037] Working principle: After the device is powered on, the power supply board converts the input AC or DC power into various voltages required by the device to power the main body 1 of the chassis. The main control board inserted into the main control board slot 6 begins initialization, starts the operating system and network management services. At the same time, the main control board actively scans and identifies all inserted service boards, fan boards and front display board 9 through the backplane bus, loads the corresponding drivers, and builds a complete device hardware topology. After the device is stable, the main control board continuously sends its management IP address, detected device alarms and performance events, and key status information such as the serial numbers of each board collected to the front display board 9 through the internal data bus. The LCD display 10 on the display board 9 displays this information. The operation and maintenance personnel can switch the content to view through the function buttons 11 on the display board 9, thereby realizing local status monitoring without external tools.

[0038] At the business level, customer-side signals are accessed via optical fiber to the customer-side port of the service board. The service board completes photoelectric conversion and signal mapping processing, encapsulating customer services into an OTN frame structure. These service data are aggregated to the line-side interface through the high-speed channel of the backplane, converted into optical signals by pluggable coherent optical modules, and finally amplified and sent into the optical fiber link for long-distance transmission. The reverse process is the same. During the entire operation, the fan board ensures that the interior of the main chassis 1 is at a suitable operating temperature.

[0039] When remote management or configuration is required, network administrators can connect to the NM interface provided by the main control board via IP network, use the standard NETCONF protocol to communicate securely with the device, and perform operations such as service configuration distribution, performance data query and alarm log subscription to achieve automated operation and maintenance. When any hot-swappable component fails, the device will issue an alarm and allow maintenance personnel to directly unplug the faulty unit and insert a new unit without interrupting power or business operations. The system will automatically identify and integrate the new component, quickly restoring the integrity and reliability of the overall system.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
