        Use an RJ45-to-DB9 serial cable to connect to the switch via the console port. The device’s default baud rate is 115200, with the initial username: root and no password. After logging in to the console, execute the command:
            show version
        to view the operating system version information.
        Insert a Juniper-compatible 100G SR4 optical transceiver produced by Moduletek into the device’s Ethernet port; the switch can correctly recognize the transceiver type.
        The switch interfaces default to the highest rate; you need to manually configure the interface to adapt to the rate of the connected optical transceiver. In configuration mode, execute the command:
            set interfaces <port_number> speed <speed>
        Note: Replace <port_number> with the target interface number and <speed> with the actual rate of the optical transceiver.
        Moduletek Limited’s optical transceivers are well compatible with Juniper-related equipment. Welcome to consult and purchase.
