Overview The H801X2CS board supports the following functions: Two 10GE upstream ports 10GE synchronous Ethernet Figure 1 External connections of the H801X2CS board Working Principle Figure 2 Working principle of the H801X2CS board The basic working principle of the H801X2CS board is as follows: The control module reports the status and manufacture information about the board, and provides interface information. The control module also manages other functional modules on the board and processes alarms. The interface module provides two 10GE ports. The synchronous Ethernet clock module extracts clock signals from the 10GE signals and synchronizes the 8 kHz clock of the control board with the clock signals. The power module supplies power to other functional modules of the board. The clock module provides clock signals for other functional modules of the board. Front Panel Table 1 Front panel of the H801X2CS board RUN: running status indicator Green: blinks every 1s The board is functioning properly. Green: blinks every 0.25s The board is starting up. ALM: alarm indicator Red: on The board is faulty. Red: off The board is functioning properly. LINK: optical fiber connection indicator Green: on The connection of the optical fiber is normal. Green: off The connection of the optical fiber is abnormal. ACT: service running indicator Yellow: blinks Data is being transmitted. Yellow: off No data is being transmitted. Port The ports of the H801X2CS board are located on its front panel. Table 2 describes the ports of the H801X2CS board Table 2 Ports of the H801X2CS board Port Function Connection 10GE optical ports Transmit two channels of 10GE signals upstream. Use an optical fiber to connect the port to the upper-layer device or the cascaded device.
