4.
Bundle network and power cables together and route them to the outer edge of the rack.
NOTE:
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.
