Follow the instructions for the model you are working on:
v Models 270 and 820 (See page 465)
v Models 800, 810, 825, 830, 840, 870, 890, SB2, and SB3 (See page 466)
Instructions for Models 270 and 820
1. Choose one of the following:
v If you are working on a Model 820, use Table 1. below to determine the service information.
This
ends the procedure.
v If you are working on a Model 270, continue with the next step.
2.
Is function 20 available on the system unit control panel?
v No: Continue with the next step.
v Yes: Select function 20 on the system unit control panel. Record the processor feature code
(characters 5 through 8). Use Table 1. below to determine the service information.
This
ends the procedure.
3. The system unit backplane is in position MB1. To determine which system unit backplane is installed,
remove the cover on the left side. See Models 270, 800, 810 - Covers. Then, continue with the next
step.
4. Examine the card positions on the system unit backplane.
v If there are card positions labeled M01 and M02, then you are working on a Model 270 with a
Network Interface Controller (NIC) embedded in the processor card.
v If there are no card positions labeled M01 and M02, then you are working on a Model 270 with a
Network Interface Controller (NIC) embedded in the system unit backplane.
