7.0 Default Jumper Settings
This section defines the factory default settings for all IXDP465 development platform jumpers, to
ensure they were not accidentally changed during transport, or repositioned by a previous user of
the platform. The jumper settings are discussed in the following sections:
• “Intel
®
IXDP465 Baseboard Jumpers” on page 12
• “Intel
®
IXP465 Network Processor/DDR Module Jumpers” on page 15
• “Intel
®
IXPETM465 Ethernet PHY Mezzanine Card Jumpers” on page 17
Each section contains a jumper summary table which provides a high-level description of each
jumper and their factory default settings, all of which must be checked prior to powering up the
platform for the first time.
