Chapter 4 Removing and replacing FRUs
Precautions before operations
FRUs (Field Replaceable Units) are components or parts that can be replaced while
making repairs. If failure occurs in your T2 and the failed part is included in any FRU,
you can repair it by replacing the FRU without disturbing other components in the
system.
This chapter mainly describes removal procedures of FRUs. Unless otherwise
documented, installation procedures will be in reverse order of removals. If any
installation instructions are documented, be sure to follow them.
The procedures described in this chapter are examples for T2 4K Elite, which also
applies to other models unless otherwise mentioned.
For the list of replaceable FRUs and location of each FRU, refer to
.
NOTE: Only Grass Valley products and components are supported. Do not install
any non-Grass Valley parts.
NOTE: Do not discard any of the removed parts such as screws or stays.
WARNING: Be sure to turn off the system and disconnect the power cord from the
product body prior to removing or replacing any parts of T2. Otherwise, electric
shock or product failure may result.
WARNING: When you attach parts of T2, be sure to use exactly the same screws as
were originally used on the parts.
WARNING: Part of T2 may be damaged by electrostatic discharge or physical
impacts. When you work on your system, be sure to wear a wrist strap for preventing
electrostatic discharge (ESD) and provide grounding.
Required tools
Phillips screwdriver #1, nippers
Turning off the T2 and disconnecting the power cord
You must always turn off your T2 and disconnect the power cord from the product
body prior to removing or replacing FRUs (Field Replaceable Units).
CAUTION: Be sure to shut down T2 with a proper procedure prior to turning off
the system. For instructions on how to shut down the system from the maintenance
mode, refer to
