\subsection{RD32 Disk Drive Device Electronics Board Removal}
The RD32 disk drive has an FRU inside it. It is the device electronics board.
Always replace the device electronics board on the RD32 before you replace
an entire RD32 disk drive.
\caution{Do not remove any of the screws that secure the cover (cover/filter
assembly) to the base casting. Removing any of the screws violates the clean area.}
\begin{enumerate}
\item Remove the three flat head screws shown in \figref{3-25} that hold the
device electronics board in place under the drive unit. Besure to locate
the one screw with the nylon washer next to the drive motor when
replaceing the board.
\fig{SHR-0296-86}{RD32 Device Electronics Board Screw Locations}
\newpage
\item Disconnect the cable from J4 (middle of board) as shown in \figref{3-26}.
The J4 connector is not keyed and can be reconnected incorrectly. Make
sure the violet and yellow wire in the connector is located near the LED
and the orange and blue wires are located toward the outer edge of the
board when reconnecting J4.
\fig{SHA-0297-86}{Disconnecting J4 from RD32 Device Electronics Board}
\item Stand the board up. Be careful not to strain any of the connectors or
cables, and tilt the board over center until it rests against the outer
frame.
\caution{Flexible circuit material is fragile and requires careful handling to
avoid damage.}
\newpage
\item Disconnect the cables from J6 and J5 as shown in \figref{3-27} from
the device electronics board. Both connectors and cables are fragile --
handle them with care.
\fig{SHR-0298-86}{Disconnecting J5 and J6 from RD32 Device Electronics Board}
\item Remove the device electronics board from the RD32.
\newpage
\item Position the jumper on the new board to the same position as the jumper
on the old board you just removed (\figref{3-28}). Also be sure the new
board has the resistor termination pack installed.

\item Replace the new device electronics board by reversing the above procedures.
\end{enumerate}
\section{Resistor Load Board Removal from System Box}
The resistor load board loads down the power supply in a diskless system
or when just the RX33 floppy drive is installed in the system box. The
power supply does not have enough of a load on it to regulate properly
in these configurations. The load board simulates the drives by drawing
enough power to regulate the power supply. You must remove the load
board whenever a hard disk drive is installed in the system box.
The resistor load board in the system box is different from the resistor load
board in the expansion boxes. The part number of the resistor load board in
the system box must be 5417163-02. The -01 version goes in the expansion
boxes.
\begin{enumerate}
\item Remove the shield (\para{3.2}).
\item Remove the three screws shown in \figref{3-29} that secure the drive
mounting bracket to the chassis.
\item Disconnect the power cable from the resistor load board.
\item Lift the load board up and out of the chassis.
\item If you are removing the load board to install a drive, remove and
discard the standoffs that the load board sat on, then install the drive by
reversing the removal instructions for that drive. Otherwise, install the
new load board (p/n 5417163-02) by reversing the above procedures.

\item Disconnect the battery cable from the system module.
\fig{MA-0078-87}{Battery Cable Location}
\item Take the battery pack out of its holder.
\item Replace the battery pack by reversing the above procedures.
\note{A new battery needs a minimttm of 25 hours of continous power on to
fully charge the battery. If the battery's charge is low, you will see an error for
the NVR when you power up the system.}
\end{enumerate}
\newpage
\section{Power Supply Removal from the System Box}
\begin{enumerate}
\item Remove the shield (\para{3.2}).
\item Disconnect the power cables from the rear of the drives. If you need
more room behind the drives, remove the three drive mounting screws
and slide the drives out part way.
\item Put the system on its side and remove the four screws shown in
\figref{3-31} that hold the power supply to the bottom of the chassis.

\section{VAXstation 2000 VR260 Monochrome Monitor}
You may need the following tools to repair the VR260 Monitor.
\begin{itemize}
\item Phillips screwdriver
\item Slotted screwdriver
\item High-voltage discharge tool (p/n 29-24717)
\end{itemize}
