50 IBM BladeCenter JS23 and JS43 Implementation Guide

3.6 Management Card

The Management Card provides a mean for making the Anchor system

information chip pluggable. Management Card’s plug is located on Base planar,

just below the DIMMs (see Figure 3-4 on page 54). The Management Card is

always present in its specially designated connector on the Base planar.

Both IBM BladeCenter JS23 and JS43 Express have only one Management

Card, located in the Base planar.

Management card contains the TPMD processor, RN50 video controller and

associated SDRAM, RISCWatch, Async and debug ethernet ports, Anchor chip

and P6 characterization connector, and it is a Customer Replaceable Unit (CRU).

3.6.1 Anchor chip on Management Card

The Anchor Smartchip resides on Management Card. This Anchor chip stores

system-specific information. The pluggable Management Card makes it possible

to transfer system-specific information from a faulty system CRU to the

replacement CRU.

3.7 Memory subsystem

For IBM BladeCenter JS23 and JS43 Express, the memory controller is internal

to the POWER6 processor. It is interfaced to memory buffer chips located on the

system board. The memory buffer chip in the POWER6 processor-based server

is the next generation Synchronous Memory Interface ASIC that connects

memory controllers to the Industry Standard Very Low Profile (VLP) Registered

DIMMs (RDIMM).

Note: The IBM BladeCenter JS43 Express has two Service Processors, one

in the Base planar, and one in the MPE planar. The Service Processor located

in the MPE planar has only I/O functions, and does not provide redundancy

nor backup support to the FSP in the Base planar.
