Step 3. Reading the Type 103 and 105 Message
A type 103 and 105 message is generated when a hardware error is detected. Use the
following steps and information to record SRN and FRU location code information.
1. Record all characters following the first 103 or 105 in the first line of the operator panel
display. This is the SRN.
2. Record all characters following the number in the first position on the second line, this is
the location code information for the first FRU.
3. Each time the reset button is pressed the operator panel display scrolls upwards one
line. When all the information has been displayed, the bottom line of the operator panel
display contains a line with 888 flashing. This indicates that the message is being
repeated.
Press the reset button and record the information in the bottom line of the operator panel
display. Continue this exercise until a line with a flashing 888 is displayed. Use the
following information to help identify the information in each line.
Note: X represent any character.
Displayed
Information
103 XXX–XXX
105 XXXX
1 XX–XX–XX–XX
2 XX–XX–XX–XX
3 XX–XX–XX–XX
4 XX–XX–XX–XX
Note: All eleven characters of the location code may not be displayed.
4. If multiple SRNs were recorded start with the SRN recorded first. If that does not fix the
problem try the remaining SRNs in the order recorded until the problem is fixed.
5. When the system halts with a flashing 888 you must power-off the system unit to recover.
Go to "Hardware Problem Determination" on page 11-1.
Step 4. Other Numbers
The only valid message types are types 102, 103, 104, and 105. Type 104 messages are
used by the manufacturing plant and should be ignored. If you have any other number
displayed, take the following actions:
1. Press the Reset button again and again until a flashing 888 appears in the first line of
the operator panel display. If you do not get a flashing 888 in the display, you should
consider the numbers as steady numbers. Go to "Hardware Problem Determination" on
page 11-1.
2. When the flashing 888 is displayed, go to Step 1 on page 8-12.
