Type 4758 - Battery Replacement Procedure - IBM iSeries 270 Service Manual

For the 2890:
b. At least one memory module is required in positions DIMM 0, DIMM 1, DIMM 2 or DIMM 3.
c. An IXS adapter card IOP (see Type, model, and part number list for part number) is required in
the IOP DIMM position. This IXS memory module is NOT interchangeable with the memory
module(s) in positions DIMM 0, DIMM 1, DIMM 2, or DIMM 3.
For the 2892:
d. Memory modules are required in pairs in either positions DIMM 0 and DIMM 1, or DIMM 2 and
DIMM 3. The only other configuration would be memory modules in DIMM 0, DIMM 1, DIMM 2,
and DIMM3.
This ends the procedure.

Type 4758 - Battery replacement procedure

For use by authorized service providers.
Use this procedure to remove or replace the PCI Cryptographic coprocessor cards batteries in Type
4758-023.
Note: Two battery replacement kits (see Type, model, and part number list ) are required to replace the
batteries in the 4758-023 card, since the card contains two batteries, and each battery replacement kit
contains two new batteries. (Individual models of the 4758 PCI Cryptographic Coprocessor family of cards
contain either two or four batteries. For cards that contain four batteries, two battery replacement kits must
be ordered.)
CAUTION:
The battery is a lithium battery. To avoid possible explosion, do not burn or charge the battery.
Exchange only with the IBM
regulations. (RSFTC227)
Attention: Any loss of battery power erases data stored in the card's protected memory and renders the
card useless.
To remove or replace the PCI Cryptographic coprocessor card's batteries in Type 4758-023:
1. Choose from the following:
v For Models 830, 840, SB2, and SB3, remove the 4758 PCI Cryptographic Coprocessor card from
the system. See the following card remove and replace procedures:
– Models 830/SB2 with FC 9074 - Cards (concurrent)
– Models 840/SB3, FC 8079 (lower half), FC 9079 Cards (concurrent)
– FC 5074, FC 5079, FC 5094, FC 5294 - Cards (concurrent)
– FC 5075 - Cards (concurrent).
v For Models 270 and 820, remove the 4758 PCI Cryptographic Coprocessor card from the system.
See the following card remove and replace procedures:
– Model 270 - Cards (concurrent)
– Model 820 - Cards (concurrent)
– FC 5074, FC 5079, FC 5094, FC 5294 - Cards (concurrent)
– FC 5075 - Cards - Concurrent
2. Find the location of the 4 lithium batteries. They are located in adjacent holders, with the Battery 2
holder above the J3 connector. Refer to the illustration below.
