A Mac Address can be blocked on a single port or all of 'em.

Just to cover all bases....
A single Mac Address usually isn't blocked on a switch. While it can be done, that's not the way it's usually used. For starters, a Mac Address can be easily spoofed. The way Port Security is used in a production environment is that only a certain number (usually 1) of Mac Address are allowed on a single port (ethernet jack). We don't specify the Mac Address...only the number that is allowed.
The reason it's set up this way is to stop an end user from plugging in a Wireless Access Point or some Rouge DHCP Server.

They do have an IT person and he is very anal about people messing with his stuff, that's the reason I didn't go any further and moved the machine to a different location.
One thing I forgot to mention about all of this is this is the second 3645 that is doing this in that spot, we initially took a different one there and it did that to us so we put the other machine back and it worked so we assumed it was a bad port in the machine. Took a completely different 3645 there and same thing. I am thinking he has something set up on his network that is blocking the machine from getting an IP address thst only affects thst model for whatever reason.

First things first. It's not your responsibility to figure out this problem. Obviously there's nothing wrong with the 3645 because it's working fine on a different port.
It's not like you can log into his switch and change any settings. That's the responsibility of the IT guy.
Last thing. You need to ask the IT guy for an IP address for the machines because it doesn't need to be left on DHCP unless the address is reserved.

Perhaps unrelated ... but some tabletop Lexmarks rebadged as Konica Minolta have known network issues. They just don't work in certain network situations. As an experiment we ordered the Lexmark versions of the same device, which worked fine on this particular network. The theory that made the most sense, was that certain kinds of network activity lock up the NIC. Read here:
Bizhub 4050 freezes/locking up
Konica Minolta bizhub 475 error code E301
bizhub 4052, 4752
Won't scan, print or access user boxes while connected to the network. MFP locks up. When Scan is pressed goes to time clock (forever). Will not print from the network or even internal reports, until the network cable is disconnected. Network traffic causes the MFP to lock up. Affects only all (4) bizhub 4052's on this network. Detail codes: (8) 0X1FFF, (5) 0X9CE2, (2) 0X4002, (1) 0X201A, (1) 0X2017, (2) 0X2008, (1) 0X2015, (1) 0X076C.

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Sorry but can't be. He put another machine on same cable and port and it works.
This is very weird issue will be interested in solution.

I don't reply to private messages from end users.
It's set to static, it won't recognize that or pick one up on it's own using DHCP. It's really odd.

Hopefully I have an answer for it, they might just leave it how I have it set but I told them to get their IT guy to look at it and see if he can figure out why it's doing what it's doing.

I would try changing the NIC speed on the MFP from auto, to a fixed speed.
I’ve had to do this on a couple of occasions. Even a machine that had been there a while, that just stopped working all of a sudden.
Interesting, in 30+ years of working on copiers I have never had to change or adjust any setting related to that. Not sure if I'll be able to work on it again but if I do I'll definitely give it a shot.
