HP BladeSystem c3000 Tower Enclosure Quick Setup Instructions

Mapping BL2x220c blades
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 crosslinks are used to 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 in instances where they cannot be used, such as when two
blades reside in adjacent device bays.
