3: Operating the Adapter Using LEDs to Determine Adapter Functionality The adapter has a single light-emitting diode (LED) display that indicates if the adapter is configured correctly and connected to an active Ethernet. Table 3-1 describes the LED. Verifying That the Adapter Driver Is Loaded Enabling the Adapter Table 3-1 Adapter LED Label Color Meaning LINK/ACT Green Link established The adapter driver should be automatically loaded at boot time. To verify, check for the presence of the cxgb3 driver: lsmod | grep cxgb3 You can load the driver manually as follows: modprobe cxgb3 To enable the adapter, enter the following as root: ifconfig IPaddress netmask mask broadcast address mtu 1500|9000 For example: Yellow Link active Red Power-on indicator (ON by default during power-on but OFF after the driver is loaded.) ifconfig eth2 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255 mtu 9000 For other systems to see the new address, you must enter new addresses in host files, DNS, or NIS as required for your system. For details, see the network documentation for your operating system. 16 007-5476-001
Verifying That the Adapter Is Properly Configured and Enabled Resetting the Adapter Use the installation tool that comes with your operating system to install and configure the adapter. You can use the ifconfig -a command to verify the configuration information, as follows: systemA:~ # ifconfig -a eth2 Link encap:Ethernet HWaddr 00:60:DD:47:81:24 inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: fe80::260:ddff:fe47:8124/64 Scope:Link UP BROADCAST MULTICAST MTU:9000 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Base address:0x3020 Memory:b9160000-b9180000 Resetting the Adapter For more information on ifconfig, see the ifconfig(8) man page. In the unlikely event that you need to reset the adapter, enter the following: ifconfig down ifconfig up where interface is name of the interface. This is usually a driver name followed by a unit number, for example, ifconfig eth0 down, for the first Ethernet interface. For more information on ifconfig, see the ifconfig(8) man page. 007-5476-001 17
