Removing and replacing FRUs

Field Replaceable Units (FRUs) are modular hardware components that can be
serviced without disturbing other components in the system. The following topics
discuss working with the Dyno controller FRUs:

The pictures in these topics show how to disassemble. Unless otherwise documented,
re-assembly is the reverse.

Unless otherwise indicated, you need only a Torx tool with T15 magnetic tip to
remove and replace parts in the Dyno controller.

You can also replace the entire Dyno controller as a FRU, as explained in

“Replacing

a Dyno controller” on page 44

.

NOTE: Only Grass Valley components are supported. Do not attempt to use
components procured from a different source.

NOTE: Do not discard any hardware unless specifically instructed to do so.

WARNING: To avoid serious injury from high currents, ensure that
the power cords are disconnected prior to removing or replacing any
parts.

CAUTION: This system contains board-level components that must be
protected from static discharge and physical shock. Wear a wrist strap
grounded through one of the system's ESD Ground jacks when
handling system components.

CAUTION: To avoid possible damage to circuit boards and other
sensitive parts, turn off the Dyno controller and disconnect AC power
before opening the top cover or removing any internal parts.
