interconnect. Depending on the configuration requirements, additional mezzanine cards and interconnects can be populated in:
•Mezzanine 1 and Interconnect Bay 2
•Mezzanine 2 and Interconnect Bays 3 and 4
•Mezzanine 3 and Interconnect Bays 3 and 4
The full-height server blade has four embedded NICs and can accept up to three additional mezzanine cards. Each embedded NIC and optional mezzanine port is mapped through the signal midplane to specific ports on interconnect bays. A full-height server blade installed in device bay 1 would have NICs mapped in the following manner:
•NIC 1 (PXE default) — Interconnect bay 1 port 5
•NIC 2 — Interconnect bay 1 port 13
•NIC 3 — Interconnect bay 1 port 1
•NIC 4 — Interconnect bay 1 port 9
Figure 12. Port mapping for HP BladeSystem c3000 full-height server blades to interconnect bays
Half-height server blades connect to a single power and signal connector on the signal midplane. The remaining signal connector is allocated to the adjacent device bay (that is, device bays 1 and 5). As a result, half-height server blades do not support four-port mezzanine cards on connector 1, and they do not contain a Mezzanine 3 connector. The extra lanes on the signal midplane are allocated to the adjacent device bay. A four-port PCIe x8 mezzanine card installed in connector 2 PCIe x8 can send x2 signals to interconnect bays 3 and 4.
