Solution

Verify eth1 interface of the Server or Application Server has link and is administratively up.  In the CLI of the Server or Application Server, run the command: 
ip addr show dev eth1

> ip addr show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
...

If eth1 has no link, but the interface is administratively up:
- Verify the switch to which eth1 connects is powered and switch port is working
- Check the cabling connecting eth1 and switch port
