MAP 0070: 888 sequence in operator panel display

Purpose of this MAP

An 888 sequence in operator panel display suggests that either a hardware or software problem has been detected and a diagnostic message is ready to be read.

• Step 0070-1

  Perform the following steps to record the information contained in the 888 sequence message.

  1. Wait until the 888 sequence displays.
  2. Record, in sequence, every code displayed after the 888. On systems with a 3-digit or a 4-digit operator panel, you may need to press the system's "reset" button to view the additional digits after the 888. Stop recording when the 888 digits reappear.
  3. Go to Step 0070-2.
• Step 0070-2
  Using the first code that you recorded, use the following list to determine the next step to use.

  Type 102

  Go to Step 0070-3.

  Type 103

  Go to Step 0070-4.

• Step 0070-3

  A type 102 message generates when a software or hardware error occurs during system execution of an application. Use the following information to determine the content of the type 102 message.

  The message readout sequence is:

  102 = Message type RRR = Crash code (the three-digit code that immediately follows the 102) SSS = Dump status code (the three-digit code that immediately follows the Crash code).

  Record the crash code and the dump status code from the message you recorded in Step 0070-1.

  Are there additional codes following the dump status?

  No

  Go to Step 0070-5.

  Yes

  The message also has a type 103 message included in it. Go to Step 0070-4 to decipher the SRN and field replaceable unit (FRU) information in the type 103 message.

  Note: Type 102 messages have no associated SRNs.
• Step 0070-4

  A type 103 message is generated by the hardware when certain types of hardware errors are detected. Use the following steps and information you recorded in Step 0070-1 to determine the content of the type 103 message.

  The message readout sequence is:

  103 = Message type (x)xxx (y)yyy = SRN (where (x)xxx = the three- or four-digit code following the 103 and (y)yyy is the three- or four-digit code following the (x)xxx code).

  1. Record the SRN and FRU location codes from the recorded message.
  2. Find the SRN in the Service Request Number List and perform the indicated action.
  Note: The only way to recover from an 888 type of halt is to turn off the system unit.
• Step 0070-5

  Perform the following steps:

  1. Turn off the system unit power.
  2. Turn on the system unit power, and load the online diagnostics in service mode.
  3. Wait until one of the following conditions occurs:
     • You are able to load the diagnostics to the point where the Diagnostic Mode Selection menu displays.
     • The system stops with an 888 sequence.
     • The system appears to hang.
  Is the Diagnostic Mode Selection menu displayed?

  No

  Go to Start of Call.

  Yes

  Go to Step 0070-6.

• Step 0070-6

  Run the All Resources options under Advanced Diagnostics in Problem Determination Mode.

  Was an SRN reported by the diagnostics?

  No

  This is possibly a software-related 888 sequence. Follow the procedure for reporting a software problem.

  Yes

  Record the SRN and its location code information. Find the SRN in the SRN Listing and do the indicated action.
