New C253-network problem

[DadO]

Machine is a brand new, initialization is caried by the book just like other c203-253-353.

I wanted to connect it to the DHCP server by selecting auto IP. After restarting the machine i couldnt see network tab in admin settings.When we printed conf page we saw that machine didnt get ip from server.

I looked at TCP/IP rj45 connector and saw that both led wasnt blinking!
I restarted and waited as long as 10 min to get to the network tab but no luck there. I did data clear in Service mode and reatrived the network tab but again no signal from the machine, like ded NIC.

I update firmware from 16 to 21 and everything is the same except password for admin seting is not 12345678 ??? machine says incorect password? W T F?

Konica will send mi trubleshoot obout machine lozzing mac adres in monday. Could this be it? or shuld i go and update firm to ver 62 whit enhanced functions 1?

THX for any replay

try setting a static ip and use a laptop and cross over. It might be the network (cable/jack/switch/router).

I would but i dont have any signal from the NIC....its ded and i cant go to the administrator via utility button since password is wrong that is "12345678" its not functioning.

First switch off tcp -power machine off -then switch tcp on then it schould work I hope.

The firmware levels you are using are 2 years old, why not upgrade to a more current version? Go from 21 to 62 to 88 then J8. After each upgrade check to see if you get your Admin mode back. I had that problem on a Bizhub 421 and I ended up copying a good card from another 421 to the card in the machine with the problem.

First go to service mode and reinitialize the machine. that should reset all to factory defaults, including the password. Then see if it will pull an address when restarted. If not manually set the IP and connect with a crossover cable to verify that the nic is functional. If the nic is not functional then replace it.

If it works from your laptop but not from the netork then you may have a switch problem, sometimes the nic doesn't negiotate the correct network speed and operation is inconsistant. In those cases you can set the speed to 100 full duplex and and set the port on the switch to match, or you can simply jack it into one of those little 4port switches and connect the switch's uplink to the jack in the wall.

BIG THX GUYS. I apriciate help.
I agree about old formware even tho i am that type of service guy "if it works, leave it! "

I will try all of the options. I did connect machine via straight cable to my laptop but no response. I will try whit cros cable. I will request special firmware from konica to reset nic if nothing else help and will upgrade machine to j8 THX pepper for the info (u saved me shourly an hour searching for correct order of verzions ).

Will let u know the result in monday, possibily a thoursday

THANKS

One other thing and I should have mentioned this before, ( but it slipped my mind) when ever you have a nic problem make sure you have turned off direct SMB hosting, there was a tech tip about a year ago indicating that on some NIC's this will send them into a loop and cause them to lock or appear to be dead.

[DadO]

I will try that one to! thx

Uf, Nothing new except i now can enter in admin mode via utility.

I flashed machine to firm verz. 66. I couldnt access admin yet so i tried via Service mode>enhanced security to create new admin password.

When i type first 8 digits machine ask to re-type the password and the freez?? Then I flashed to ver 88 and from there i can aces admin tab but Netwok tab dosent exist .

I cant access in Direct SMB hosting since there is no network tab to shut it off.

I got this from KM

The Network button will disappear under the following
conditions
• Auto IP enabled
• DHCP Setting OFF
• BOOTP Setting ON
• ARP/Ping Setting ON
• AUTO IP Setting OFF
the network interface will only be accessible if an IP address
will be assigned by ARP/Ping or BOOTP.

Easies way to recover from this condition is to execute
following command from the windows command line -->
arp -S [ip-address] [MAC-address]
for example
arp -S 192.168.0.20 00-20-6b-55-98-FE

If Auto IP is enabled, at least AUTO IP Setting or ARP/PING is
available. If only ARP/Ping is enabled, the network i/f can be
recovered as mentioned above. If only AUTO IP is enabled, the
engine will take a IP address from the subnet 169.254.0.0 /16.


I type it via CMD window but nothing happens since machine cant recieve the command. I noticed that when am in admin tab for 1 min machine display following : " WAITING FOR ARP COMMAND". Apparently machine and computer CANT communicate via TCP/IP line and now am 100% ashured that i got defective mainboard.


Thoughts?
