TROUBLESHOOTING 138
Network (cont.)
System starts up slowly
then displays one or more
DHCP error messages on
the Control Panel.
Possibly one of the following:
• Network cable is connected to the wrong
RJ-45 port
• No cable/wrong type of cable is
connected to the network port
• Network cable or connection
is faulty
• Network is faulty
• System searches for a nonexistent DHCP
server because DHCP is enabled by
default on the E-41, but the customer’s
network is not using DHCP
• Ethernet interface on the E-41
motherboard is faulty
• System software is corrupted
1. Make sure that the correct cables are connected to the
correct ports on the E-41 back panel. The lower RJ-45 port is
the copier/printer interface; the upper RJ-45 port is the
network interface.
2. If the green LED on the (upper) RJ-45 network port is
not lit, check the cable connection of the upper RJ-45
network port and the network. Make sure that the cable is a
straight-through cable, not a crossover cable (see
page 122).
3. If the network cable is a straight-through cable and not a
crossover cable and is properly connected to the (upper)
RJ-45 network port, connect a new network cable to the
(upper) RJ-45 network port.
4. If the problem persists, ask the network administrator
to check Network Setup.
5. If the problem persists, ask the network administrator
to check other devices on the network.
If other devices are not functioning, the problem may
be with the network.
6. If the problem persists, reinstall system software
(see page 105).
Corrupt system software may cause the system to hang.
7. If the rest of the network is functioning properly
and the problem persists, replace the motherboard
(see page 65).
