or refer to the IBM Sales Manual for information on the
compatibility of hardware and software for xSeries
servers. The Sales Manual is updated periodically as new
features and options are announced that support these
servers.
Limitations: This BladeCenter H Chassis requires 200 to
240 V ac power.
Planning information
Customer responsibilities: This product is designated as
customer setup. Customer setup instructions are shipped
with the product.
Configuration information
BladeCenter H Chassis configuration:
A control panel
located on the right side of the unit contains the following
status LEDs:
• Power good
• Chassis location
• Over temperature
• Information
• General fault
Two USB ports are located at the bottom right of the
control panel, and a DVD-ROM drive is included. An
optional USB-attached 1.44 MB diskette drive is available.
Four power modules are front loading for serviceability.
The rear housing contains:
• Two hot-swap, redundant blower assemblies in the
center, mounted one on top of the other
• Ten I/O module bays
• One standard management module for
KVM/Management and one additional management
module bay
Rack installations: The BladeCenter H Chassis 9 U
rack-drawer enclosure is designed to be installed in a
19-inch rack cabinet designed for 28-inch deep devices,
such as the NetBAY42 ER, IBM S2 42U SR, IBM S2 25U
SR, or NetBAY11.
If you choose not to use an IBM rack:
• The rack must meet EIA
 -310-D standards for
mounting flanges and hole locations.
• The front to rear distance of the mounting flanges must
be between 698.5 mm and 762 mm (27.5 and 30
inches).
• The thickness of the mounting flanges must be
between 1.9 mm and 3 mm.
• The mounting flanges must have either 7.1-mm (.28-in)
diameter holes or 9.6-mm (.38-in) square holes on the
standard EIA hole spacing.
• The rack must have a minimum depth of 70 mm (2.76
in) between the front mounting flange and inside of the
front door for appropriate cooling.
• The rack must have a minimum depth of 157 mm (6.2
in) between the rear mounting flange and inside of the
rear door to install the server and make space for
cable management.
• The minimum side-to-side clearance in the rack
between the front and rear mounting flanges must be
467 mm (18.2 in) to accommodate the width of the
server and the slide mounting brackets.
• The minimum side-to-side clearance in the rack
between each door and the mounting flanges must be
484 mm (19.1 in.) to accommodate the slide mounting
brackets.
• The rack must not prevent the flow of cool air into the
front of the rack and hot air out of the rear of the rack
(front and rear doors, if present, must be perforated).
• It is recommended that any side and top panels be
used to try and prevent any unnecessary recirculation
within the rack. In addition, it is also strongly
recommended that any adjoining racks be sealed
between them, also to prevent recirculation. Any
openings between, above, or below the rack
equipment, can cause significant increase in inlet
temperature (and hence increase fan and blower
speeds undesirably) from this recirculation, so it
should be avoided if at all possible.
• All empty EIA space in the rack must be closed off with
filler panels to prevent the recirculation of air within
the rack.
• The weight-handling capacity of the rack must be able
to support the maximum rack configuration, including
all servers, external cables, and PDUs.
• The rack must provide proper stabilization so that the
rack does not become unstable when servers are
pulled out for service.
Power considerations: BladeCenter H Chassis comes with
one pair of 2,900-watt 200 to 240 V ac power modules.
These standard power modules support blade server bays
one through seven with power redundancy.
