Wireless enabled LOM package configuration

Use this information to set configuration of wireless enabled LOM package.

To enable wireless function of the server, complete the following steps:
  1. Install the wireless enabled LOM package, see Install the system board assembly and LOM packages.

  2. Define the usage scenario and choose the most suitable one from the preset topologies, see Wireless enabled LOM package preset.

  3. If no topology in presets are applicable, it is optional to create a customized one, see Customized configuration.

  4. Enable Wi-Fi/LTE Connectivity on Lenovo XClarity Controller.

    Note: To enable LTE, SIM card installation is required (see Install the SIM card). LTE service is provided by authorized mobile service carriers in respective countries or regions. Server must have a cellular plan from a service carrier to connect to the LTE network.

Inside the wireless enabled LOM package, there is an embedded switch. It works as a router with LTE function, WLAN (AP/Client mode), and 1 GbE ports for uplink and downlink.See more information of the ports:

  • 2x 1GbE SFP ports (port 3 and 4): support 1000 Base–X SFP only

  • 2x 1GbE RJ45 ports (port 5 and 6): support 10/100/1000 Mbps

  • WLAN interface: work as uplink in client mode or downlink in AP mode

  • LTE interface: work as uplink port only. Supports only nano SIM

  • Dedicated internal 10GbE port: connected to the OS (it is called LOM1-Switchboard in Windows OS)

  • Embedded Switch CLI can be accessed by SSH from Management port (port 7) but dedicated address (192.168.70.254)
    • User name: oper

    • Password: (use the same password as XCC)

  • By default, Embedded Switch has active DHCP server on all its physical down-link ports, included Wi-Fi if it is in AP mode

  • IP assignment range:

    • Downlink ports: 192.168.71.x

    • WLAN (AP mode): 192.168.74.x

    • Dedicated internal 10GbE port to the OS (it is called LOM1-Switchboard in Windows OS): 192.168.73.x

Wired networking ports (port 17) are enabled by default. LOM1-Switchboard, Uplink, Downlink, Management, WLAN and LTE interface belong to different VLANs. Embedded switch operates at L3 routing.
  • LOM1-Switchboard (br-x86_lan): default IP is 192.168.73.254/24. DHCP server is enabled by default

  • Uplink (cloud_wan / lte_wan / wifi_wan_sta): default setting is DHCP client

  • Downlink (br-edge_lan): default IP is 192.168.71.254/24. DHCP server is enabled by default

  • WLAN in AP Mode (br-wifi_lan_ap): default IP is 192.168.74.254/24. DHCP server is enabled by default

  • WLAN in Client Mode (wifi_wan_sta): default setting is DHCP client

  • Management port (br-mgmt_xcc_lan)

  • XCC: Can be accessed from Management port only by default. Default setting is DHCP client, fallback IP for XCC is 192.168.70.125/24. Default IP is 192.168.70.254/24. Can be set to DHCP client, or be set as DHCP server.

Note:
  • Uplink/Downlink ports will be changed based on topology preset. Users can adapt configuration via uci CLI commands and save it to customized preset.

  • Fail-over (Cloud Port & LTE) feature is disabled by default, users need to enable it through embedded Switch CLI as follows:
    sudo uci set network.cloud_wan.metric='10' 
    sudo uci set network.lte_wan.metric='30' 
    sudo uci set network.wifi_wan_sta.metric='20' 
    sudo uci commit network 
    sudo /etc/init.d/network restart
    After completing the setting, system starts the function of fail-over/fall-back among port 6 (cloud_wan/eth2), WLAN in Client mode (wifi_wan_sta/wlan0), and LTE port (lte_wan/wwan0).

WLAN configuration

WLAN networking (AP mode and client mode) is disabled by default in ThinkSystem SE350. Users can enable/disable wireless networking and choose mode in XCC GUI (Edge Networking page) or via Embedded switch CLI.

LTE configuration

Wireless networking ( LTE) is disabled by default in ThinkSystem SE350. Users can Enabled/Disabled LTE via XCC GUI (Edge Networking page) or via Embedded Switch CLI.
  • Use embedded switch CLI to set LTE configuration.

  • SIM card PIN number and APN are needed to enable LTE.

BMC network bridge

BMC network bridge is an configuration to select the outbound interface to access to BMC management port. There are four options as shown below. The default is “None”, which means only management port can access XCC interface.
