Technical Product Specification
Introduction
Note: Due to the midplane's CompactPCI* bus segments, some limitations exist with regard to system
slots. Refer to
Section 3.2, “Working with Board-Level Components” on page 35 and Section 3.2.1,
“Removal and Installation of Boards” on page 36 for details.
1.5 Chassis Management Modules
The ZT 7102 is the central management component for all Intel
®
NetStructure™ platforms that are
PICMG 2.16-compliant, including the ZT 5085. It uses standards-based interfaces, allowing
management of third-party IPMI-based products within an Intel NetStructure platform. It
communicates with the components in the ZT 5085 via point-to-point IPMB buses in a unique star
topology to achieve comprehensive, highly available, and secure management.
The ZT 5085 supports two redundant ZT 7102s that operate in active/hot standby modes. Two
redundant
PICMG 2.16 switches must be installed for two redundant CMMs to fully synchronize.
Synchronization of data exchanged via the IPMB connection occurs without the dual switches, but
100% synchronization requires both switches.
