IMPLEMENTATION OF A UTILITY MODEL

In the detailed description of the implementation of the utility model given below, numerous implementation details are provided, intended to provide a clear understanding of the present utility model. However, it will be obvious to a person skilled in the subject area how the present utility model can be used, both with and without these implementation details. In other cases, well-known methods, procedures and components have not been described in detail, so as not to unnecessarily complicate the understanding of the features of the present utility model.

In addition, it will be clear from the above presentation that the utility model is not limited to the given implementation. Numerous possible modifications, changes, variations and replacements, preserving the essence and form of the present utility model, will be obvious to specialists qualified in the subject area.

This technical solution is implemented as a single device, namely a stackable Ethernet aggregation-level switch for telecom operators and corporate clients.

The declared Ethernet switch provides the ability to connect 48 ports (interfaces) of the SFP+ form factor (10/100 Mbit/s), 4 ports (interfaces) of the SFP28 form factor (10/25 Gbit/s), 2 ports (interfaces) of the QSFP+ form factor (40 Gbit/s).

In addition, the Ethernet switch supports traditional functions such as:

Hot-swappable redundant power supply;

Supports front-to-back airflow direction;

Support for Control Board on COM Express TYPE 6 platform.

The declared Ethernet switch contains the following elements.

Main board. The main board has 48 10/100 Mbps ports, 4 10/25 Gbps ports, 2 40 Gbps ports, 1G management port, USB and serial console port.

Management port is a port that is used for remote management and configuration of a network device.

The main module is implemented on the basis of ASIC BCM56170 and is connected to the STM32F103 controller via the PCIex1 bus.

The network interface connections are directly connected to the Serdes interfaces of the BCM56170 switching chip without a PHY, ensuring minimal latency and reduced power consumption.

The main module uses 12VDC and 5VDC from the hot-swappable power module. The built-in DC/DC power supplies are used to generate 3.3V, 1.8V, 1.2V, 1.0V, 2.5V, 1.25V from 12VDC. Each DC/DC is monitored to provide emergency power-off if the DC/DC voltage level deviates from the monitored threshold. The system power-on sequence starts from high voltage to low voltage.

The STM32F103 controller is responsible for controlling the main module and peripheral devices, hereinafter MCPU - this is a built-in service processor for controlling all system modules. It is able to control and monitor various aspects of the device at the hardware level. MCPU monitors hardware parameters such as temperature, voltage, fans and sensors. It is responsible for the sequence of switching on the built-in DC / DC. MCPU monitors and controls via SMBus, I2C buses, as well as via discrete GPIO input / output channels.

Fans. The declared device contains 5 fans, which provide the direction of air flow "from front to back".

Fan control module.

The fan control module is connected to the MCPU via the I2C bus and the GPIO line and is implemented on the main module. The main functions of the fan control module are power distribution to 5 cooling modules, as well as the formation of pulse-width modulation (PWM) signals and reading of tachometer readings from each cooling module using commands from the MCPU. The control module provides the ability to "hot" replace cooling modules.

Indication module. The indication module is used for indication on the front panel of the switch and for implementing a button for manual reset of the switch.

Ethernet switch central processing unit module.

The central processor module (Control Plane) is implemented in the COM Express Compact form factor, on which the operating system and software are deployed, under the control of which traffic management is carried out; it is connected to the ASIC via the PCIex1 bus, and to the MCPU via the USB bus and the UART data transfer interface.

The operation of the device is shown below according to the diagram (Fig. 1):

Power supply of 220V is supplied via two connectors on the rear panel, for each power supply unit (PSU). Two PSUs are needed for redundancy with the hot-swappable function. The PSU has a standby voltage of 5V, it is converted on the main board using DC-DC to 3.3V. The MCPU starts, it checks for the presence of the PSU, reads the necessary data via the SMBus bus. If the check is successful, the MCPU starts 12V, checks the power system and turns on all other power supplies and the necessary control signals to start the ASIC BCM56170. After a successful start, it goes into SLASH mode and transfers control to the central processor module. Further in the cycle, it polls the PSU, DC-DC modules, temperature sensors, controls the fan speed, and also configures the SFP modules via the I2C bus. The central processor module is engaged in the transmission and processing of information.
