To support network connections for specific signals, install an
interconnect module in the bay corresponding to the embedded NIC or
mezzanine signals.

Bay-to-bay crosslinks
For bay-to-bay communication, the enclosure midplane provides
four-trace SerDes signals between adjacent bays.
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 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. Onboard
Administrator disables the device bay crosslinks in instances where
they cannot be used, such as when two 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. Onboard Administrator disables the interconnect bay
crosslinks in instances where the crosslinks cannot be used, such as
when two different modules reside in adjacent horizontal interconnect
bays.
