Kyocera 3645 not grabbing an IP address.

[Necrocannibal]

Had a customer buy some new machines to replace some old 1135s, 4 2640s and 1 3645. All machines work fine except the 3645, it won't grab an IP address. Put one of the 2640s where the 3645 was and it does, put the 3645 where the 2640 was it does.

Makes no sense but it only won't grab an IP address at this one spot in this office and will everywhere else but the 2640s will grab one where the 3645 won't. Same network, same ip range, same everything, very odd.

Have you tried setting a static IP address?

Yep, it wouldn't pop up on the network or even show an IP address on the status page, move it to another spot in the office and works fine.

Sounds like you've got a bad cable or network port. Does your laptop pick up a DHCP address? =^..^=

Put the ipaddress in the machine with the network cable unplugged.

Confirm with status page than plug into network

Re: Kyocera 3645 not grabbing an IP address.

Is the router/switch port going bad where you tried to plug the 3645 in? Quick test would be to take a small 4 port switch with you and plug the cable from the wall into the switch and then plug the switch into the machine, if it picks up an address, the router/switch port is going bad. Had a case a couple of years ago on a 6525 that would lose the DHCP address randomly. Plug a laptop into the port and it would pick up an address every time. Finally convinced IT to switch the jack to another port on the switch and it worked fine still is. It is worth a shot.

I agree with blackcat. The best thing he can do at this point is plug in his laptop and see if it pulls a DHCP address. That way, you'll eliminate either the machine or their network as the problem and go from there.

Everything else picks up an IP address there and works like it should, I moved the 3645 to a different spot and put a 2640 there. The 3645 is the only thing that doesn't work in that spot, it's weird.

That rules out a bad port on the switch or anything on their network. It's possible that the the Mac Address is blocked. Not likely, but possible.

Re: Kyocera 3645 not grabbing an IP address.

PS - Describe the network in the office. What kind of switches, routers, ect?

Do they have an IT person?

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.

Re: Kyocera 3645 not grabbing an IP address.

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.
