2. See “Locations — Models 830, SB2 System Unit with FC 9074 Base I/O Tower”
on page 709.
Replace the following FRUs in order one at a time until the problem is
resolved. See “Chapter 4. Removal and Installation Procedures” on page 617.
Note: Be sure to IPL in SLOW OVERRIDE mode after each replacement.
a. Clock card in location M06A in the 830 System Unit.
b. JTAG cable
c. Processor Regulator card in location M01
3. This is a Model 840, SB3 System Unit and FC 9079 Base I/O Tower.
See “Locations — Models 840, SB3 System Unit with Processor Tower and FC
9079 Base I/O Tower” on page 719.
Replace the following FRUs in order one at a time until the problem is
resolved. See “Chapter 4. Removal and Installation Procedures” on page 617.
Note: Be sure to IPL in SLOW OVERRIDE mode after each replacement.
a. Clock card in location M19 in the 840 System Unit
b. JTAG cable
c. Regulator card in location M04 in the 840 System Unit
d. Regulator card in location M07 in the 840 System Unit
This ends the procedure.
CMPRES1
The compressed device and the compression IOA are not compatible.
This ends the procedure.
CRYPBAT
The batteries for the IBM 4758 cryptographic adapter card need to be replaced.
Attention: If you remove any of the batteries without first backing up the power
with a fresh battery, the data in the card’s protected memory could be lost, which
would render the 4758 Adapter card useless and require replacement of the 4758
Adapter card. Because the 4758-023 Adapter card contains 4 batteries, and the
Battery Replacement Kit contains only 2 batteries, DO NOT attempt to remove or
replace batteries unless you have two Battery Replacement Kits (PN 09J8199).
(Individual models of the 4758 PCI Cryptographic Coprocessor family of cards
contain either 2 or 4 batteries. For cards that contain 4 batteries, two battery
replacement kits must be ordered.) Refer to “Type 4758 – Battery Replacement
Procedure” on page 687 for additional information.
This ends the procedure.
CTLPNCD
The interactive card, or the Processor Capacity card, that plugs into the control
panel assembly is the failing item. If the type number from the FRU information is
zero, contact your next level of support. Otherwise, get the location from the
Reference Code Table (N02-A or N02-B). Use the type number from the FRU
information to determine the part number from the “Type, Model, and Part
Number list” on page 885. Exchange the failing item. Go to either “Models 830/SB2
with FC 9074 – System Unit Control Panel (NB1)” on page 667 or “Model 840/SB3
