CHAPTER 2
HARDWARE PREPARATION AND INSTALLATION
2.1 INTRODUCTION
This chapter provides unpacking instructions, hardware preparation information,
and installation instructions for the MPB.
When you unpack the MPB from its shipping carton, verify that all items are in
good condition. Save packing material for storing and shipping the MPB.
NOTE
Should the MPB arrive damaged, save all packing material, and
contact the carrier’s agent.
2.2 HARDWARE PREPARATION
This portion of the manual explains how to prepare the MPB before use, as well
as how to configure the MPB for system operation. This section also explains
MPB installation in the MMDS and MEVB.
The MPB has been factory tested and is shipped with installed jumpers. A jumper
installed on a jumper header provides a connection between two points in the
MPB circuit. The MPB has two types of jumper headers: three-pin and two-pin
with a cut-trace short. A cut-trace short has a copper trace between the feed-
through holes (bottom or solder side of the MPB). Table 2-1 describes each type
of jumper header.
The MPB has four jumper headers (for which Table 2-2 is a quick reference
guide). You may re-configured these jumper headers to customize MPB
functionality. The following paragraphs explain each jumper header function.
There is also an insertion point (E1) for connecting an external ground. Figure 2-1
shows the location of the MPB jumper headers and the insertion point.
There are two versions of the M68MPBF333: B and C. On the B version the
MCU is installed in a production socket on the board (Figure 2-1 shows the B
version board layout). On the C version the MCU is installed in a clam-shell
socket on the board (Figure 2-2 shows the C version board layout).
