interconnects. It connects embedded Ethernet NICs to the internal facing ports on the Ethernet
interconnect. Depending on the configuration requirements, additional mezzanine cards and
interconnects can be employed:
• 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 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

Half-height server blades connect to a single power and signal connector on the NonStop 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 NonStop
