Suggested action
• Make sure that the iR-M1 is powered on.
• Make sure that the power cable is properly con-
nected to the back panel of the iR-M1 and is
plugged into a wall socket. Verify that the power
cable is not plugged into a switchable wall socket
that has been powered off. (see “Preliminary check-
out” on page 3-1).
• Check internal power supply cable connnections to
the moutherboard, HDD, and power supply.
• Check the AC power cable and ground cable con-
nections to the power supply and power switch (see
“Internal cable connections” on page 4-9).
• If the above does not correct the problem, replace
the power supply (see “Power supply” on page 4-
28).
• Check the UIB cable connection to the UIB and
motherboard (see “User interface board” on page 4-
13).
• If the problem persists, replace the UIB cable.
• If the problem still persists, replace the UIB.
• Make sure that the DIMM(s) are inserted correctly
into the socket(s) (see “DIMM” on page 4-20). If
the problem persists in a product with more than
one DIMM socket, insert the DIMM into another
socket.
If the DIMM fails in the second location, replace it.
• Check power supply cable connections to the
motherboard and power supply.
• Check AC power cable connections to the power
supply (see “Internal cable connnections” on page
4-9).
• If the problem persists, replace the power supply
(see “Power supply” on the 4-28).
• Check the power supply cable connection to the
motherboard (see “Motherboard” on page 4-17).
• Make sure that all other cables are properly con-
nected to the motherboard.
• If the problem persists, try replacing the
motherboard battery (see “Motherboard battery” on
page 4-21).
• If the problem still persists, replace the
motherboard.
