2 Ethernet cards on Sangoma Linux 7.5.1805

I've Sangoma Linux 7.5.1805 I installed a second ethernet card into motherboardls and since then the integrated interface stopped working As I plug cable into the second NIC the network starts to work again. ifconfig shows me 2 interface eth0 and eth1 I even have 2 ifcfg files **/etc/sysconfig/network-scripts/ifcfg-eth0**

DEVICE=eth0
BOOTPROTO=static
ONBOOT='yes'
IPADDR=19.2168.16.98
NETMASK=255.255.255.0
GATEWAY=192.168.16.2
DESCRIPTION="unset"
TYPE=Ethernet
ZONE=trusted
PEERDNS=no
IPV6_PEERDNS=no

**/etc/sysconfig/network-scripts/ifcfg-eth1**

DEVICE=eth1
BOOTPROTO=static
ONBOOT='yes'
IPADDR=19.2168.16.216
NETMASK=255.255.255.0
GATEWAY=192.168.16.2
ZONE=trusted
TYPE=Ethernet
PEERDNS=no
IPV6_PEERDNS=no

**ipconfig** I also can ping the 192.168.16.98 from another computer **lspci -vv | grep net** How can I make both cards work?
