connector on the rear face of a Blade Enclosure, to the LOWER port, a connector on the rear face of
the Blade Enclosure just above, and the LOWER port, another connector on the rear face, to the
UPPER port, a connector on the rear face of the Blade Enclosure just below, through LAN cables

enclosures.
The EM cards can read the status information of the Blade Enclosures and display the information

in to any Web console through the link to the Web console. See Chapter 4 for details of the Web
console.

overall racks and the upper limit of power consumption allocated for each Blade Enclosure.
Power linkage feature is applied to all over the Blade Enclosures connected with each other.
