    Cisco switch 6500 / Bizhub c451 Dropping off

    Has anyone out there experience the dropping off having to reboot every morning to get the unit back on-line or on the network? We have a couple of C451's that every morning the customer has to reboot in order to get them back on the network. We have the switch and copiers at 100 full duplex.

    I haven't run into a daily issue. But, many times I have had to service a copier that had 'dropped off-line' I found another device that was using the same IP address.

    With the older Minolta print controller, specifically the Pi......ok forget the model number, used on the Di251 of which I had about 50 connected, the controller could lock up to the point where a power recycle wouldn't work. Had to fuss around with resetting the factory defaults and firmware loads to get them back to working condition.

      Problem is Power over Ethernet

      This has caused problems for all the Konica Units we ever had (On a Cisco Catalyst 6500). 7145s, C450, C451s. You can have the Network Admin turnoff PoE on the relevant ports, (but that still caused problems for use.) I ended up using Netgear switches (stuck to the back of the units using velcro) to clean out the cisco garbage and clean up the traffic going to both the emperon and the fiery.

      Problems went away.
