Establishing RMC IP Hardware Connections

Using DHCP to Establish an IP Address

12
For IP address configuration, there are two options: DHCP or static IP. The following subsections
provide information on the setup and use of both.
Note: Both options require the use of the RMC's micro-USB serial port, refer to Figure 1-4 on
page 9.
LAN Network (LAN RJ-45) connections to the SGI UV 3000 RMC are always made via the
port.
For DHCP, you must determine the IP address that the RMC has been assigned; for a static IP, you
must configure the RMC to use the desired static IP address.
To use the serial port connection, you must attach and properly configure a micro-USB interface
cable to the RMC's
CNSL
Hardware Requirements" on page 11.
When the serial port session is established, the console will show an RMC login, and the user can
login to the RMC as user "root". Note that there is not (by default) a password required to access
the RMC via the port.
CNSL
To obtain and use a DHCP generated IP address, plug the RMC's external RJ-45 network port
( ) into a network that provides IP addresses via DHCP; the RMC can then acquire an IP
WAN
address.
To determine the IP address assigned to the RMC, you must first establish a connection to the
RMC's USB port (as indicated in the section "USB-Connected Console Hardware Requirements"
on page 11), and run the command "ifconfig eth1". This will report the IP address that the
RMC is configured to use.
To switch from a static IP back to DHCP, the configuration file
/etc/sysconfig/ifcfg-eth1 on the RMC must be modified (see additional instructions
in the "Using a Static IP Address" section). The file must contain the following line to enable use
of DHCP:
BOOTPROTO=dhcp
port. Configure the serial port as described in "USB-Connected Console
