I am using static IP address of 10.1.0.8

+ I see on my switch no "live" network connection - so it
appears that the NIC is not active.
+ I cannot ping a local server
+ I cannot access an Internet site like www.fedora.org
+ gkrellm shows no activity
+ nslookup finds no DNS server
I am able to ping localhost or the hostname (resovled via /etc/hosts)
itself. Just cannot ping remote sites.

+ ping 10.1.0.11
PING 10.1.0.11 (10.1.0.11) 56(84) bytes of data.

/sbin/route:
================================================================
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.1.0.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
default 10.1.0.200 0.0.0.0 UG 0 0 0 eth0

Additionally, I checked:
+ lsmod | grep atl2
alt2 32024 0
+ cat /etc/modprobe.conf
alias eth0 atl2
