Upgrading the Control Unit

! Do not remove any of the existing carriers.

! Refer to the Control Unit Diagram on the flip side of System Planning Form 1.

If you are installing an expansion carrier, remove the rightmost module from the control unit and set it aside. See Figure 9-3 on page 9-11.

! CAUTION:

Before removing any cords from the module, make sure they are labeled first for easier replacement.

! Install any expansion carriers.

See “Installing Expansion Carriers” in Chapter 2.

! Install or replace any modules. If you are upgrading from Release

3.0or later, go to Step 6.

See “Installing the Modules” in Chapter 2.

NOTE:

If you are replacing an 012 module with an 016 (T/R) module, you will need to perform a Board Renumber after completing the upgrade. See System Programming for more information about Board Renumber.
