Installing 575 System Hardware

A 575 system controller is any 575 CPU installed in slot 1. If you want to

replace a 575 system controller, follow the steps below.

NOTE: Read and abide by the warnings and cautions at the beginning of

this section.

1. Before you remove the 575 system controller, save the memory of the

system controller, any 575 secondaries, and any third-party masters.

2. Ensure that all power is disconnected from the VMEbus base and that

the battery is disconnected.

3. Remove the 575 system controller.

4. Ensure that the dipswitch configuration is the same for the new 575.

Refer to Section 4.10 for information about dipswitch configuration.

5. Install the new 575 system controller.

6. Power up the 575 system.

7. Reconnect the battery after the PCG LED lights up on the 575 system

controller; that is, when the LED on the bottom right-hand side turns

on. See Figure 4-19 for the location of the LEDs.
