instructions on step 6 on page 2-17 and then return here and continue.
3. Exit Service Processor Menus and remove the power cable.
4. Disconnect all external cables.
5. Remove the side cover
6. Record the slot numbers of the ISA and PCI adapters. Label and record the
location of any cables attached to the adapters. Remove all the adapters.
7. Remove the second processor card (if present). [If second processor removed,
ensure first CPU cable is installed.]
8. Record the position of the memory DIMMs. Remove all installed memory DIMMs
except for one pair from the first Memory card.
Note: The memory DIMM pair must be installed in slots that are next to each
other. For example, install the pair in J1 and J2, not J1 and J3.

14. Turn the power on.
15. Wait for the operator panel to stabilize at a checkpoint.
Note: Checkpoints E1F2, E1F3 and STBY are stable as soon as they appear.
Other checkpoints may take up to 3 minutes to assure stability, depending on
system configuration.
Does the operator panel stabilize with code E1F2, E1F3, E1F7, or STBY?
NO Go to “Step 1540-3” on page 2-20.
YES Go to “Step 1540-4” on page 2-21.
