Getting Started
Refer to Intel's board-specific manuals for connectivity options and limitations. For document
ordering information, see
2.4
Setup and Configuration
The ZT 5085's midplane has several features that can be used to tailor the system for use in a
specific environment. The following topics address Chassis Management Modules (CMMs), slot
assignments, setting V(I/O), and disabling the power standby switch.
2.4.1
CMM Configuration
For detailed information about optional CMM configuration and diagnostics, refer to the Intel®
NetStructure™ ZT 7102 Chassis Management Module Technical Product Specification and
specific Intel® NetStructure™ processor board user documents. See
Reference"
2.4.1.1
Operating with Redundant CMMs
The following requirements apply in systems configured with two CMMs:
1. Switches must be installed in slots 2 and 21.
2. The switches must provide the HEALTHY# output signal.
3. The switches must support port 19 (LP19). Port 19 of switch slot 2 is routed on the backplane
to CMM slot 1A. Port 19 of switch slot 21 is routed on the backplane to CMM slot 1B.
4. The switches must have a network connection between them, either via the inter-fabric port
(LPf) or via external connections.
Note: Optionally, the CMMs may be connected through an external ethernet switch. See the Intel®
NetStructure™ ZT 7102 Chassis Management Module Technical Product Specification for more
information.
2.4.1.2
Operating without CMMs
The CMM controls the BD_SEL# signal to each slot. It asserts BD_SEL# to enable a board's
"backend" power. The ZT 5085's midplane provides jumpers for grounding each slot's BD_SEL#
pin.
For the system to operate correctly, either:
At least one CMM and no BD_SEL# jumpers J1 through J20 must be installed
Or:
No CMM and all BD_SEL# jumpers J1 through J20 must be installed.
The BD_SEL# jumpers do not tie the IPMBs together so there is no management if there is no
CMM. Refer to
