DC Power Connectivity

Before installing the switch system, make sure an over-current DC circuit breaker of up to 100A is installed at the rack.

Connect the DC power supplies in the switch according to the following recommendations:

  1. Make sure circuit breakers are in their “Off” state.

  2. Ground the PSU with a 14 AWG wire.

  3. Using an 8 AWG wire for the power feed, unscrew the screws on the DC PSU terminals, connect the DC power cord lugs, and tighten the screws.

  4. Repeat all steps for secondary PSU.

  5. Turn on the switch by switching the circuit breaker to the “On” position for both PSUs.

Configuration

  1. Connect the host PC to the Console (RJ-45) port.

  2. Configure a serial terminal program.

  4. Initial configuration

    1. Onyx (MLNX-OS): Go through the configuration wizard. For further information, please refer to: https://docs.nvidia.com/networking/category/mlnxos.

    2. ONIE: Please refer to the ONIE User Manual - https://docs.nvidia.com/networking/category/oniesw.

    3. Cumulus: By default, the MGMT port will acquire the IP from DHCP. You can cross reference the MAC of the switch with your DHCP server (MAC can be found on switch label) or using "ifconfig eth0" (when using MGMT0).
