Installation Instructions
Before Installation (steps 1-8)
VERY IMPORTANT
MES should be installed without delay, after
receipt, to avoid multiple MCLs needed for
the microcode.
Net Priced Feature
All parts removed from this machine are IBM
property and must be returned to IBM.
1.0 Machines Affected
IBM 3745 Model 41A.
This feature should only be applied on the
machine serial for which it is specified.
2.0 Related BMs and ECs
None.
3.0 BMs to be Installed
Install one of the following FFBM.
FFBM 17G5549 - Convert a 3745 41A to 61A
(4MB memory size)
or
FFBM 17G5550 - Convert a 3745 41A to 61A
(8MB memory size)
or
FFBM 17G5551 - Convert a 3745 41A to 61A
(16MB memory size)
and 17G5536 - Installation Instructions.
4.0 Preparation
1. Familiarize yourself with the purpose and
details of the installation instruction before
negotiating machine time with the customer.
2. Check all items listed on the BM(s) to deter-
mine that all parts have been received.
3. The installation must be performed off-line.
4. Ensure that RETAIN search has been per-
formed and all prerequisites have been
installed.
Perform a search using 3745CCUPGRADE as
SAS keyword
5. To check if a new MCLs level is necessary,
perform a RETAIN search using
3745UPGRADE CODE LEVEL for the TDR
which gives the most recent level of micro-
code available for this machine (model).
To install the last level of MCLs, the most
efficient way is with the LIC upgrade proce-
dure. Use the RETAIN search, 3745ECA134
COF , for the TDR which explains the proce-
dure for ordering the latest level microcode
from COF.
Third party can get the latest level of code
through their normal microcode ordering
procedures.
MCLs can be obtained from RETAIN (If if the
customer provide an RSF link), or by
ordering the 3746 optical disk MCL via CCSS.
6. Follow the unpacking instructions attached to
the case to unpack the MES material.
Do not damage the packing boxes, they will
be used for repacking.
7. Before starting Model conversion ensure that
the complete 3745 is available.
Additional information:
All parts to be removed should be handled
carefully. Returnable parts must be received
at the factory in good order.

5.0 Programming
5.1 Diagnostic Programs
To reflect this change, CDF will be upgraded in
Step 11.0. This is essential to allow internal
diagnostics to be run properly.
5.2 System Programs
The customer must update the control program
to implement this change.
6.0 Purpose and Description
6.1 Purpose
Convert a 3745 Model 41A to a 3745 Model 61A.
6.2 Description
Remove the TCM CCU enclosure, PSTY1s,
Air Moving Device, and associated cabling.
Install a new CCU enclosure with Fans, new
PSTY1Bs, and associated cabling.
Logics cards will not be re-used.
7.0 Installation Time
To be reported as MES
8.0 Tools/Materials Required
