eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group on raspberry pi 3b+ model

Hi.
when I connect Rpi3b+ to Laptop through LAN cable it works fine and I can connect so easily.
Even I find the LAN cable detected in path below and transfer the fileds easily

sys/class/net/eth0/carrier = 1

But when I connect Rpi to my hardware device its not at all detected and no LEDs are blinking.
what could be the issue?

sys/class/net/eth0/carrier = 0 :x

the output of below command is as
ip addr show eth0
eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether b8:27:eb:31:02:c3 brd ff:ff:ff:ff:ff:ff


Please can you suggest on this NO-CARRIER and DOWN group to make a configuration from Rpi to my Hardware device.

1) Replace device
2) Stop making duplicate posts
My first computer was an ICT1500, my first "personal" computer was the Science of Cambridge Mk14, followed by a TRS-80 Model I later
