Virtual Connect modules 231
Stacking Links screen
To access this screen, click the Stacking Links link in the left navigation tree.
Be sure to connect any Ethernet module stacking cables before running the network setup wizard.
IMPORTANT: HP strongly recommends that redundancy be maintained in stacking links to
ensure continued connectivity of servers to the external networks.
Stacking links are formed between Ethernet modules in two ways:
• Externally, using stacking cables to connect modules
• Internally, using dedicated cross connects between horizontally-adjacent modules
The domain stacking mode determines how stacking links are configured between Ethernet modules in the
VC domain.
Use this screen to configure the domain stacking mode.
To configure the domain stacking mode, select one of the following:
• Full Stacking is the default stacking mode for the VC domain. In Full Stacking, all Ethernet modules
within the domain are connected by horizontal cross connects or by stacking cables.
• Horizontal Stacking disables all vertical stacking links. In horizontal stacking mode, each horizontal
bay pair is a separate logical interconnect. For example, if bay 1 and bay 2 are populated, they form
a logical interconnect.
• Primary Slice Stacking disables all stacking links outside of the primary slice. The primary slice is the
primary and standby interconnect modules for the enclosure. In primary slice stacking, the primary slice
is a logical interconnect.
