5.12.3.2 Procedure - Establish Network Connectivity to SAM1620-D
The list below outlines the different actions required to enable and use the front panel
Ethernet interface on a SAM1620-D. If the upgrade is being performed over the backplane
Ethernet interfaces from one of the hub blades, skip these steps.
1. Login to the SAM1620-D front panel serial console using the id root and password
root.
2. Set the environment variable that defines the IP address allocated for the SAM1620-
D's front panel Ethernet interface.
# setenv ip1addr W.X.Y.Z
# ifconfig eth1 W.X.Y.Z
3. If your file server (for SMART EC files) is on a different subnet,
# route add default gw W.X.Y.Z (you need to do this each time you reboot).
If you use the Uboot environment variable gatewayip, the route is set automatically
at reboot (setenv gatewayip W.X.Y.X)
4. If the local subnet is not a class 'C' subnet, you may need to also execute the
command:
# ifconfig eth1 netmask ... to alter the netmask used by the Ethernet
interface
If you use the Uboot environment variable netmask1, this subnet mask is set
automatically at boot up (setenv netmask1 netmask)
5. Ping the file server containing the SMART EC files. You should get a response if the
Ethernet cable is connected.
6. Set the environment variable that keeps the front panel Ethernet interface enabled
following a reboot.
# setenv enable_front_panel_ethernet y
