I have two questions for anybody who can help i have N+ soon.

one(1): what is the purpose of the NIC leds A. does it tell you the NIC is sending are receiving or B. that the system board is working?.

two(2):If a server is configre for DHCP and a client is using a static IP address what will hapen. A. someone else will try to use the Ip or B that person will be the sole owner of that ip address?

let me know what you all think , i have been getting mixed answers for these two questions!

    There is no standard for nic leds. They are primarily for troubleshooting purposes. If there is 1 led, it is usually to indicate connectivity to a hub or switch (often called a link light). If there are 2 leds, the second one is an "activity" led which goes on and off when there is network traffic detected. If there are more leds, they are usually an indication that the nic is multispeed (eg: 10/100) and the appropriate led will be lit based on the manufacturers specs. I don't believe that the leds have anything to do with the system board.

    Your question about DHCP server and static IP is not real clear to me. The DHCP server will not assign an IP addres to a client with a static IP because no request will be sent from the client to the server for an IP address. If someone statically assigns the same IP address as one that is already in use, there would be an error generated advising that the address is in use (unless that client is not logged on to the network). So the answer is your option "B" - the person who logs on first with a particular IP address will be the sole owner of that IP address.

    Just wanted to add that the answer to the first question can be found here also:

    Your second question wasn't clear to me either, though I think jheal00 answered it already. Also a DHCP server can ping an IP address before it issues it to a client to check if it is not in use (manually assigned) already. If you know that certain IP addresses are manually assigned, you can exclude those from the range from which the DHCP server issues addresses.
