Configuring a Replacement CPU Assembly
Configuring a Replacement CPU Assembly
Description
When only the main CPU board is replaced, it is necessary to
reconfigure it with certain data that is critical for instrument operation.
This information includes the IP address, time, date, instrument serial
number, and the host name. If possible, it is best to capture this
information from the instrument before replacing the main CPU board.
Procedure
Capturing Critical Data for the CPU Board
Ensure that all information is recorded exactly as it is displayed.
1. To view the host name and IP address, press
System and
Configure I/O.
NOTE The Ethernet Address is embedded in the CPU, and it will change when
the CPU is replaced. When the Ethernet Address is changed the Flash
Memory board will reset the IP address and host name to the default
factory values.
2. To view the instrument serial number, press
System, More until
(2 of 3) is displayed, and
Show System. Refer to the note below before
proceeding.
a. Confirm that the serial number on screen matches the number on
the rear panel tag.
b. If the instrument is not functional, use the serial number on the
rear panel tag.
NOTE The serial number stored in memory is used to enable all licensed
options. If the stored serial number is different from the rear panel
serial number sticker, then the instrument has an incorrect CPU board
installed or an incorrect serial number was entered into the CPU when
it was last replaced. If the two serial numbers do not match, determine
the cause and correct the problem.
If you cannot correct the problem, and you use the rear panel serial
number on the new CPU board, the keywords associated with the
stored serial number will no longer enable the options. In this case,
contact Agilent Technologies sales and service office for the correct
license numbers for your instrument. To contact the Agilent
Technologies sales and service office refer to “Contacting Agilent
Technologies” on page 60.
