I have an 8203-E4A system that I just purchased a network card for (feature 5623). It is a dual-port Ethernet adapter. I currently have the system up and running in production with an existing 5623 card in it. I am using both ports (one for LAN access, other for Operations Console connectivity). I purchased the second card for failover. I wanted to swap these cards, so that I can verify that the one I just purchased works. I am unsure as to how that will work as far as my connectivity to the system is concerned.
In the networking realm, is a POWER system like Microsoft (ie., I can change the card and the system will tie the new hardware to the existing ETHERNET Device Description), or like UNIX (network configuration is tied to a MAC address so when I change the card I will lose connectivity [console & LAN] to the system? Has anyone done this before?
