Hmc Configuration Rules - IBM p5 590 System Handbook

only one or two processor books and more I/O drawers than can be
configured in the primary system frame should carefully consider their future
system growth requirements to determine which Expansion Rack
combination to purchase.
The number of Bulk Power Regulators (FC 6186) and Bulk Power Distribution
Assemblies (FC 7837) varies, depending on the number of processor books
and I/O drawers and battery backup features (p5-595 only) installed in the
p5-590 or p5-595 server. For detail the number of BPRs and BPDs required
for different combination, refer to p5-590 and p5-595 Sales Manual.
Battery backup
An optional Integrated Battery Backup is available, if desired. The battery backup
features are designed to protect against power line disturbances and provide
sufficient power to allow an orderly system shutdown in the event that the power
sources fail. The battery backup features each require 2U of space in the primary
system frame or in the Expansion Rack (FC 8691).
The Integrated Battery Backup, Primary or Redundant-Front Mounted (FC
6200) is used to back up the front-mounted power subsystem. It interfaces to
the power regulators with the FC 6240 cable. If battery backup is desired, one
battery backup (FC 6200) should be ordered for each power regulator in the
front power subsystem.
The Integrated Battery Backup, Redundant Rear Mounted (FC 6201) is used
for the rear-mounted power subsystem if redundancy is desired. It interfaces
to the power regulators using the FC 6240 cable. If redundant battery backup
is desired, one FC 6201 should be ordered for each power regulator in the
rear power subsystem.
The Integrated Battery Backup, Primary or Redundant-Front Mounted (FC
6200) is a prerequisite to ordering the Integrated Battery Backup, Redundant
Rear Mounted (FC 6201).
If additional external communication and storage devices are required,
7014-T00 or T42 racks should be ordered. There is no limit on the quantity of
7014 racks allowed.

5.2.11 HMC configuration rules

In order to configure and administer a partitions on p5-590 and p5-595 systems,
you must attach at least one IBM Hardware Management Console for pSeries to
the system. We recommend that a second HMC is configured, and each HMC
has a second network connection for service and management. The HMC can be
ordered as a separate product, as shown in Table 5-6 on page 134. For more
information about the HMC, see Chapter 8, "Hardware Management Console
overview" on page 195.
