4.1.2 Data Transport Connector (Zone 2)
Zone 2 consists of one 120-pin HM-Zd connector, labeled P23, with 40 differential pairs. This data
transport connector provides the following signals:
• Two 10/100/1000Base-T/TX Ethernet base fabric channels (four differential signal pairs each,
16 signals total).
• Two 2 Gbit Fibre Channel ports on the extended fabric (two differential signal pairs each, eight
signals total).
The connector used is AMP/Tyco part number 1469001-1, Intel part number A66621-001.
Figure 17, “Data Transport Connector (Zone 2) J23” on page 75 shows a face view of the
connector.
The following naming convention describes the signals on this connector. Signal direction is
defined from the perspective of MPCBL0001.
