Configuring Network Attributes

The procedures described in this chapter assume that you have already installed and powered-on
the system according to the instructions in this document. Since the system comes with a pre-
configured DHCP, you may find the explanation in Section 2.7.1.1 sufficient. In case a manual
configuration is required, please refer to the instructions in Section 2.7.1.2.
2.7.1.1 Disable Dynamic Host Configuration Protocol (DHCP)
DHCP is used for automatic retrieval of management IP addresses..

After inserting a power cable and confirming the green System Status LED light is
on, make sure that the Fan Status LED shows green.
If the Fan Status LED is not green, unplug the power connection and check that the
fan module is inserted properly and that the mating connector of the fan unit is free of
any dirt and/or obstacles. If no obstacles were found and the problem persists, call
your Mellanox representative for assistance.
