T05-104-07 iR-M2 error messages and conditions (Continued)
Symptom
Network (con’t)
System starts up slowly
then displays one or more
DHCP error messages on
the Control Panel.
Suggested action
1. If the green LED on the 10/100BaseT
connector is not lit on the iR-M2 back
panel, check the cable connection to
the back panel and the network. Make
sure the cable is the correct type.
2. If the network cable is the correct type
and is properly connected to the back
of the iR-M2, connect a new network
cable to the back of the iR-M2.
3. If the problem persists, have the net-
work administrator change the default
in iR-M2 Network Setup.
4. If the problem persists, make sure that
the network administrator has checked
other devices on the network.
If other devices are not functioning,
there could be a problem with the net-
work.
5. If the problem persists, reinstall system
software (see page 4-56).
Corrupt system software may cause
the system to hang.
6. If the rest of the network is function-
ing properly and the problem persists,
replace the motherboard (see page 4-
26).
Possible cause
Possibly one of the follow-
ing:
• Network cable or connec-
tion is faulty
• Network is faulty
• System searches for a non-
existent DHCP server be-
cause DHCP is enabled by
default on the iR-M2, but
the customer’s network is
not using DHCP.
• Ethernet interface on the
iR-M2 motherboard is
faulty
• System software is cor-
rupted
