Troubleshooting
Network (continued)
Unable to connect to
the network, or the green
LED on the RJ-45
network port is not lit.
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
•
If the E-45 requires a static IP
address (for example, in a non-
DHCP network environment), it may
need to be reconfigured. A static IP
address is deleted when system
software is reinstalled.
•
System software is corrupted
•
Network interface on the E-45
motherboard is faulty
1 If the problem persists, have the network administrator
check Network Setup. To configure a static IP address (if
applicable for the customer site), work with the network
administrator as described on
.
2 If the problem persists, make sure that the network
administrator has checked other devices on the network.
If other devices are not functioning, the problem may be
with the network.
3 If the problem persists, restore the backup, or reinstall the
system software (see
).
Corrupt system software may cause the system to hang.
4 If the rest of the network is functioning properly and the
problem persists, replace the motherboard (see

to check Network Setup. To configure a static IP address
(if applicable for the customer site, as in a non-DHCP
environment), work with the network administrator as
described on
2 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.
