Installing and Cabling the HP CCI Solution
IMPORTANT:
Be sure to route the cables for your enclosure in a manner
that provides rapid, easy access to the console connector for a local client
device, such as a laptop computer. Also be sure to route the cables so
they do not block or restrict airflow from any of the fan openings.
5. Repeat steps 1 through 4 for each Blade PC enclosure you have
installed.
Null-Modem Cable
If you are cabling a serial device such as a laptop computer to the
console connector on the Integrated Administrator, be sure to use a
null-modem cable and not a straight-through cable. The following
table defines the wiring of a null-modem cable.
