Figure 14: PMC Sites 2 and 3 − Pn4 Connector Pinout
Note: a
S The signals available at pins 30 and 31 depend on the settings of the on−board
switches SW7−1 to SW7−4. See
a
section "Switch Settings" on page a 42
a
for further
details.
a
S By default, the PMC I/O Ethernet signals (ETH_xxx) are routed to the on−board
switch via magnetics. As an assembly option the magnetics can be by−passed and
the Ethernet signals can be accessed via an installed PMC uplink module from
Motorola. Consult your local Motorola representative for details.
a
S By default the signals at pins 61 to 64 are routed the zone 3 connectors where they
are available as PMC I/O signals. As an assembly option these signals can be routed
to the on−board Ethernet switch as further 100BaseTX interface. Consult your local
Motorola representative for details.

Parallel ATA Connector
The blade provides one parallel Advanced Technology Attachment (ATA) connector
which allows to connect a 2.5" hard disk to the blade. The location of this connector is
shown in the following figure.
