VPDCONC

For use by authorized service providers.
The failing component is the VPD concentrator hardware.
1. Choose from the following options:
v If you are on a Model 270, 800, 810, or 820: Replace the system unit backplane at location MB1.
See Locations and addresses for the model you are working on to find part information and links to
the remove and replace procedures.
This ends the procedure.
v If you are on a Model 825, 830, 840, 870, 890, SB2, or SB3: Continue with the next step.
2. Is this system a Model 825?
v No: Continue with the next step.
v Yes: Replace the system unit backplane at location CB1. See Model 825 - System unit backplane -
CB1.
3. Is this system a Model 830 with SB2 system unit and FC 9074?
v No: Continue with the next step.
v Yes: Replace the following FRUs in order one at a time until the problem is resolved. Be sure to IPL
in SLOW OVERRIDE mode after each replacement. See Locations — Models 830, SB2 system unit
with FC 9074 base I/O tower for part number and remove and replace information.
a. Clock card in location M06A in the 830 system unit.
b. Network interface controller (NIC) card in location M06 in the 830 system unit.
This ends the procedure.
4. Is this a Model 840, SB3 system unit and FC 9079 base I/O tower?
v No: Continue with the next step.
v Yes: Replace the clock card in location M19 in the 840 system unit. Be sure to IPL in SLOW
OVERRIDE mode after each replacement. See Locations — Models 840, SB3 system unit with
processor tower and FC 9079 base I/O tower for part number and remove and replace information.
This ends the procedure.
5. This is a Model 870 or 890 system unit with FC 9094 base I/O tower. Replace the Network interface
controller (NIC) card in position M41 in the 870 or 890 processor tower. See Locations — Models 870
and 890 with an FC 9094 Base I/O Tower.
This ends the procedure.

VPDPART

For use by authorized service providers.
A VPDPART may be failing.
Attention: AC power must be removed from the system before removing or installing regulator 3.
Perform the following to determine the part for the failing VPDPART. The address of the failing frame and
unit is shown in the second, third, and fourth characters of the 4 leftmost characters of the SRC. 11-x
xFFU-xxxx (F=frame and U=unit).
