4.1 Backplane Connectors
4.1.1 Power Distribution Connector (Zone 1)
Zone 1 consists of P10, a 34-pin Positronic header connector that provides the following signals:
• Two -48 VDC power feeds (four signals each; eight signals total)
• Two IPMB ports (two signals each, four signals total)
• Geographic address (eight signals)
• 5.55 Amperes are allocated to MPCBL0001 on the -48 VDC redundant power feeds. This is
equivalent to 200 Watts at the minimum input voltage (-36 VDC). The Zone 1 connector and
pin out is compatible with the backplane for Intel NetStructure
