105 XXXX SRN being displayed, XXXX is the SRN. 105 = Message type 1xx 2xx 3xx 4xx = encoded SRN c01 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = First FRU location code c02 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Second FRU location code c03 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Third FRU location code c04 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Fourth FRU location code 1. Determine the SRN by translating the rightmost two digits of each position within the encoded SRN (1xx 2xx 3xx 4xx) using the table at the end of the following substep. You can cycle through the numbers again by pressing the Reset button. 2. The FRU location codes translate into an eight-digit location code (AB-CD-EF-GH). Each digit of the eight-digit location code is presented as a three-digit number in the operator panel display. A B C D E F G H = Eight-digit location code c01 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = First FRU location code c02 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Second FRU location code c03 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Third FRU location code c04 1xx 2xx 3xx 4xx 5xx 6xx 7xx 8xx = Fourth FRU location code Note:If a ccx (x can be any digit from 2 through 9) is encountered as part of the location code, only the part of the code that is different from the location code of the previous FRU is shown. To form the complete location code of the next FRU, substitute the information following the ccx into the location code of the previous FRU. For example, if the previous FRU location is: c01 100 200 300 401 500 601 700 800, and the next FRU location is listed as: cc2 602, the complete location code of the next FRU is: cc2 100 200 300 401 500 602 700 800. To identify each digit of the location code (AB-CD-EF-GH), translate the right-most two digits using the following table. See "Location Codes" in this chapter to determine the physical location of the resource. xx Value xx Value xx Value xx Value 00 = 0 11=A 21=K 31=U 01 = 1 12=B 22=L 32=V 02 = 2 13=C 23=M 33=W 03 = 3 14=D 24=N 34=X 04 = 4 15=E 25=O 35=Y 05 = 5 16=F 26=P 36=Z 06 = 6 17=G 27=Q 07 = 7 18=H 28=R 08 = 8 19=I 29=S 09 = 9 20=J 30=T 3. The only way to recover from an 888 type of halt is to power the system unit Off. Return to the MAP step that directed you here.
