3.
If more than one enclosure is installed in the rack, use a CAT5
patch cable to connect the enclosure link-down port on the
upper enclosure to the enclosure link-up port on the lower
enclosure.
NOTE: The enclosure link ports are designed only to
support c-Class enclosures in the same rack. The
enclosure link-up port on the top enclosure is the service
port, and the enclosure link-down port on the bottom
linked enclosure is unused.
NOTE: The BladeSystem c-Class enclosure link ports
are not compatible with the BladeSystem p-Class
enclosure link ports.

To utilize intelligent power discovery, connect the cables to an
intelligent single-phase AC module and then to the OAs.
For more information on intelligent power discovery, see the
Intelligent Power Distribution Unit User Guide on the Hewlett
Packard Enterprise website.
Mapping to interconnect ports
Several port types are referenced in the following tables.
•
Examples of 1x ports are 1-Gb Ethernet (1 GbE) switch
modules and Fibre Channel interconnect modules.
•
An example of a 2x port is a Serial Attached SCSI (SAS)
interconnect module. (Reserved for future use.)
•
Examples of 4x ports are 10-Gb Ethernet (10 GbE)
interconnect modules.
Gen8 servers have FlexibleLOM adapters that have the same
•
port mapping as the previous generation server blade
Embedded NICs.
NOTE: 1x and 2x port mezzanine cards interface with
single-wide interconnect modules. 4x port mezzanine
cards interface with double-wide interconnect modules.
The term "1x/2x" refers to the number of interconnect lanes per port
provided by the controller. The more lanes provided per port, the
higher the data transmission rate coming from that port.
