Required Cabling
NOTE: Direct Attach Copper cables listed in the options section below are fully supported by Hewlett Packard Enterprise.
HPE recommends use of these cables. If not identified as a "supported" DAC, VC will allow the connection to proceed if the
discovery process indicates the cable meets the following criteria: connector=copper pigtail; transceiver code=active cable or
passive cable; speed >=10Gb; length between 1m and 7m, inclusive. The connection is logged as an unsupported cable. Prior
to requesting support from HPE, a DAC from the supported list must be used to validate the issue.

Stacking
Stacking links are used to interconnect Virtual Connect Ethernet/FlexFabric Modules when using more than
Configuration
one enclosure or when using more than two Virtual Connect Ethernet/FlexFabric Modules in a single
enclosure.. The following provides recommended configurations.
Interconnecting the modules allows all Ethernet NICs or CNAs on all server blades in the Virtual Connect
domain to have access to any Virtual Connect Ethernet uplink port. By using these module-to-module links, a
single pair of uplinks can be used as the data center Ethernet network connections for the entire Virtual
Connect domain, and allows any server blade to be connected to any Ethernet network.
