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)

FFBM 17G5550 - Convert a 3745 41A to 61A

(8MB memory size)

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

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.

Installation Instructions

To save installation time and machine down

time, some tasks will be performed after the

General IPL Section (Step 11.4).

When hardware installation is complete and

before starting Test Procedure section (11.0),

each CE should check the other CE's work.

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
