The following base drive removal and replacement procedures apply to all 3570 Cxx Models located in
EMEA, and are listed in the most logical order of a typical repair action:

FID EA: Drive Logic Card

Removal of Drive Logic Card: To remove the drive logic card, item

in Figure 317 on

page APPENDD-14, follow the steps below if not done before:

Note: If you are removing the drive logic card only to gain access to another FRU blocked by the drive

logic card, go to step 3. If you plan to replace the drive logic card with a new part, you should
attempt to recover the microcode EC and link level of the drive logic card with the following
procedures.

1. For library models, do the following:

a. Attempt to display the EC level and link level:

1) Press the Mode push button if the operator Options menu is not displayed.
2) Select the drive number that you are working on.
3) Select Services from the Options menu and press Enter.
4) Select Microcode Level from the Services menu and press Enter.

b. If the microcode EC level was displayed in the previous step, write the EC level, link level and

date in “Microcode EC Level History Log” on page PROC-38; and then return here.

c. If you have access to an FMR tape at the microcode EC and link level, go to step 3.

d. If you don't have access to this level of FMR tape, but your machine failure will allow you to

create a FMR tape, do so following the procedure on “Making FMR Tape from Scratch
Tape—Library Models” on page PROC-31 or “Making FMR Tape from Scratch Tape—Drive-Only
Models” on page PROC-31, then go to step 3.

e. If the microcode EC level cannot be displayed, go to step 3.

2. For drive-only machines, there is no current way to read the microcode EC level unless that can be

gathered by the host system. Continue with step 3.

3. Perform the prerequisite procedures for your 3570 model listed on Figure 316 on page APPENDD-13.

Note: Attention:

The logic cards are ESD sensitive. Special care must be used when handling

ESD parts. See “Working with Electrostatic Discharge (ESD) Parts” on page PROC-3.

4. See Figure 317 on page APPENDD-14. Disconnect the flat cable, item

, from the drive logic

card. Pull the cable retainer

away from the connector housing

far enough to release the flat

cable

. Leave the flat cable connected to the drive analog card unless you are going to install a

new drive analog card or flat cable.

Note: The flat cable should be folded as shown in Figure 317 on page APPENDD-14. This will

prevent it from being damaged when installing or removing the cooling pack.

5. Remove the drive logic card, item

, from the mother board, item

Note: You may need to lightly pry the card away from the mother board at each end of the connector

to loosen the drive logic card for removal.

Replacement of Drive Logic Card—Library Models

Note: Before replacing the drive into the library frame, write down the drive serial number that is located

on the drive frame, on the left side when you are facing the front of the drive assembly. You will
need this number in one of the following steps, if you are installing a new drive logic card.
