• 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
IBM BladeCenter H Chassis 4Tx model comes with one pair of 2980 W power
supplies. These power modules support blade server bays 1 through 7 with power
redundancy.
Cable orders
Each IBM BladeCenter H Chassis contains one or two management modules with
Ethernet connections. The RJ-45 connectors provide a 10/100 Base-T interface (at
either half or full duplex) for connecting twisted-pair cable to an Ethernet network.
Cabling is not included with the BladeCenter. To connect the management module(s)
to a repeater or switch, use an unshielded twisted pair (UTP) cable with RJ-45
connectors at both ends. For 100 Mbps operation, Category 5 cabling must be used.
For 10 Mbps operation, Category 3, or better, cabling must be used.
Each BladeCenter H Chassis can contain several switch modules which have cabling
requirements of their own, none of which is included with the BladeCenter.
Installability
The IBM BladeCenter H Chassis requires approximately 30 minutes for installation.
Installation includes unpacking, setting up, and powering on the system. Additional
time is required to install an operating system, additional options, or features.
