Device Bay Crosslinks; Interconnect Bay Crosslinks - HP BladeSystem c7000 Setup And Installation Manual

Device bay crosslinks

Device bay crosslinks are wired between adjacent horizontal device bay pairs.
For half-height blades, these signals connect a four-lane PCIe module to a partner blade such as a tape blade
or a PCI expansion blade. For full-height blades, these signals are used to connect a PCIe module to a partner
blade in the lower adjacent bay and require a PCIe pass-thru mezzanine card installed in mezzanine
connector 3. The Onboard Administrator disables the device bay crosslinks when they cannot be used, such
as when two server blades reside in adjacent device bays.

Interconnect bay crosslinks

Interconnect bay crosslinks are wired between adjacent interconnect bay pairs.
You can enable these signals to provide module-to-module connections, such as Ethernet crosslink ports
between matching switches, or Virtual Connect modules as stacking links. Onboard Administrator disables
the interconnect bay crosslinks when they cannot be used, such as when two different modules reside in
adjacent horizontal interconnect bays.
