4. Disconnect all external cables (such as parallel, serial 1, serial 2, serial 3, serial 4,
keyboard, mouse, 100BaseT Ethernet, SCSI).
5. Remove both side covers, as described in “Removing the Covers” on page 301.
6. Record the slot numbers of the PCI adapters. Label and record the location of any
cables attached to the adapters. Disconnect any cables attached to the adapters
and remove all the adapters.
7. If the system has a one-way processor card with memory DIMMs installed, record
the DIMM locations and remove all the memory DIMMs except the ones in slots 1
and 8 (pair A). If a memory riser card with memory DIMMs is installed in slot
P1-M1, record the DIMM locations and remove all the memory DIMMs, except the
ones in slots 1, 2, 15, and 16 (quad A). Make sure the minimum memory DIMMs
configuration of 256 MB is installed in the memory riser card in the first slot of the
system, or the one-way processor card if there is no memory riser card. Use either
a pair or a quad, depending on the memory DIMMs/memory riser cards available.
8. Replace the second memory riser card from slot P1-M2 (if present), with a memory
filler card if one is available. Otherwise, record the DIMM locations, remove all the
memory DIMMs from the second memory riser card, and install it back in slot
P1-M2.
9. Disconnect the SCSI cable from the SCSI connector on the system board.
10. Disconnect the diskette drive cable from the diskette drive connector on the
system board. (Removing fan 3 enables better access).
11. Disconnect the internal parallel and debug port cables.
12. Disconnect the signal and power connectors from the 2-pack and 6-pack
assemblies.
13. Remove the hot swap disk drive(s) from the hot swap bays.
14. Disconnect the signal and power connectors from all the SCSI devices except the
CD-ROM drive.
15. Connect the system unit power cable to the wall outlet and wait for OK on the
operator panel display.
16. Turn on the power.
17. Wait for the operator panel to stabilize at a checkpoint.
Note: Checkpoints E1F2 and E1F3 are stable as soon as they appear. Other
checkpoints may take up to 3 minutes to ensure stability, depending on
system configuration.
Does the operator panel stabilize with code E1F2, E1F3, E1F7 or 20EE000B?
NO Go to “Step 1540-3” on page 55.
YES If the system has a one-way processor card with additional memory DIMMs to
be tested, go to “Step 1540-4” on page 55.
If the system has memory riser cards with additional memory DIMMs to be
tested, go to “Step 1540-6” on page 57.
If there are no additional memory DIMMs to be tested, go to “Step 1540-8” on
page 58.
