Resolving A Vga Monitor Problem - IBM Power System 8335-GCA Manual

15. Is the system an 8348-21C, and are all 32 of the DIMM locations populated with 32 GB DIMMs?
If Then
Yes: Continue with the next step.
No: Go to step 18.
16. Use the baseboard management controller (BMC) to update the system firmware. For instructions,
see Updating the system firmware by using the BMC. Does the problem persist?
If Then
Yes: Continue with the next step.
No: This ends the procedure.
17. Is your system is an 8335-GTB?
If Then
Yes: Replace the Baseboard management controller (BMC) card. Go to "8335-GTB locations" on
page 121 to identify the physical location and the removal and replacement procedure. If
the problem persists, continue with the next step. Otherwise, this ends the procedure.
No: Continue with the next step.
18. Replace the system backplane.
v If your system is an 8335-GCA or 8335-GTA, go to "8335-GCA and 8335-GTA locations" on page
111 to identify the physical location and the removal and replacement procedure. Then, continue
with the next step.
v If your system is an 8335-GTB, go to "8335-GTB locations" on page 121 to identify the physical
location and the removal and replacement procedure. Then, continue with the next step.
v If your system is an 8348-21C, go to "8348-21C locations" on page 133 to identify the physical
location and the removal and replacement procedure. Then, continue with the next step.
19. Does the problem persist?
If Then
Yes: Go to "Collecting diagnostic data" on page 109. Then, go to "Contacting IBM service and
