Will Setting DHCP affect my static IP addresses?

[d3lt4]

Sorry it's about Mac's. I know most ppl here like normal pc's including me, but I have never touched a server in my life (til yesterday)
I am trying to set up a network at the business where I work. Here is what there is.
1gb cajun p120 switch
g4 xserve (second gen with os x)
T1
a few macs and some pc's
Belkin pr-N router that supplies wireless internet to a number of clients who pay monthly.

Right now the xserve has assigned the T1 modem, itself, and the router a static ip address. I need to set up DHCP for the rest of the computers, but if I set up DHCP will it mess up any of the static ip addresses, or will they remain the same?

please help. Even if you only know this for a normal linux or windows server.
Edit: removed rant

If the xserve is assigning IP addresses that would mean you're already using DHCP (unless there's something apple specific going on) so I suspect the devices have default IPs, or someone else has assigned them.

Nope, they will remain the same. DHCP client does not run if you assign a static IP.

Harsh, but think of the experience, and maybe if you do a good job you can ask for a bonus...

give us an idea of these static addresses. Do they start down in the xxx.xxx.xxx.2,.3 range?
If so, set up your dhcp server to start at xxx.xxx.xxx.100
This will prevent address conflicts.

IPs are IPs, regardless of whether it is OSX or Windows or Linux.

Just set your DHCP range outside of what the static IPs and no worries.

My boss assigned the Ip adresses.
They are in the xxx.xxx.xxx.1-10 range

So I will set my ip range above this. Thanx for all the help.

Edit: My boss dd not assign the IP's on the server. They are self assigned. Would the server reassign them in this case? Would that slow down the internet over the router because of NAT being used through the server and then through the router?

yeah just set the DHCP like kami said, you're fine

ok I set DHCP and two of four computers picked up the DHCP assigned IP addresses, subnet mask, DNS, and router ip. Unfortunately 2 of them didn't. THe ones that did work had self assigned IPv6 numbers where as the two that didn't did not. I don't think it is the network card in these two computers, because My cp had the same problem when I tried to hook it up. It said that a network cable is umplugged, but when i put it into the belkin router it worked fine. So to make a long story short what do I need to do to make these computers see the network and pick it up.

Secondly when I enable NAT on the server it doesn't work. I made sure DHCP only assigned one IP address and then enabled NAT to test it out. The first CP took the IP address and the second took an IP in the NAT IP range. The problem was that the one with the NAT IP address couldn't connect with the internet. It saw the network and such, but it just couldn't connect to the internet. Then I switched to DHCP w/o NAT and added a few more possible IP addresses and it worked fine. What can I do to fix this? the only real options for NAT are to turn it off and on.

anyone?
