Chapter 1. Reference Information

This chapter provides an overview of the Eserver pSeries 690, including a logical description and a

physical overview of the system. Additional details pertaining to the server are also provided. They include

the following:

v Memory overview and ordering rules

v General description of the operator panel

v Cabling rules

v System location rules and descriptions

v Powering on and powering off the system

v Power flow

The pSeries 690 server is a multiprocessor, multibus system composed of the following subsystems:

v 7040 Model 61R, a 24-inch wide and 42-EIA-high rack unit that also contains the following:

– An 8-EIA unit power subsystem, consisting of two redundant bulk power assemblies that distribute

bulk power at 350 V to each of the subsystems.

– An optional 2 EIA-unit integrated battery feature (IBF), which is available in either a redundant or

non-redundant configuration.

v 7040 Model 681 Processor Subsystem, a 17 EIA-unit processor subsystem, which contains the

processors, L3 cache, memory, and service processor and a 1 EIA-unit media subsystem containing a

diskette drive, a CD-ROM, and an operator panel, with space for up to three additional optional media

There is an option to expand the number of RIO (in this case RIO-2) ports to 28. This allows up to eight

RIO-2 I/O subsystems, if cabled in RIO or some combination of RIO and RIO-2, each with 2

GB-per-second transfers on each planar. Processor speeds up to 1.5 GHz and 1.7 GHz are also

available. Additional memory cards that operate at the higher 567 MHz bus speed are available.

v 7040 Model 61D I/O Subsystem, 4 EIA-units, which can have up to 20 PCI adapters and up to 16

DASD disk drives.

This subsystem may also be purchased to allow 10 or 20 PCI-X adapters, for use with the RIO-2

cabling option. Additionally, there is an option that allows 1 GB RIO-2 on each remote I/O port. RIO-2

allows up to 2 GB I/O transfers when cabled as a single planar loop (four CEC RIO-2 ports per I/O

v A Hardware Management Console (HMC), which provides a standard user interface for configuring and

operating partitioned systems. One HMC can support multiple partitions on multiple systems.
