I/O Module Port Mapping─Half-Height Blades

Standard LOM (Dual-Port) and Network Daughter Card

(Quad-Port) Mapping

Each standard LOM has two port connections. For a half-height blade in bay n:

Integrated LOM, connection 1 connects to I/O module A1, port n. Integrated LOM, connection 2 connects to I/O module A2, port n.

Half-height blades with network daughter card (M710HD) hosts two network controllers (LOM1 and LOM2), each with two port

connections. For a half-height blade in bay n:

• LOM1, connection 1 connects to I/O module A1, port n. LOM1, connection 2 connects to I/O module A2, port n.

• LOM2, connection 1 connects to I/O module A1, port n+16. LOM2, connection 2 connects to I/O module A2, port n+16.

NOTE: If the I/O modules A1 and A2 are not quad-port capable, then the LOM2 ports (NIC3 and NIC4) gets disabled

during system boot.

For example, in a half-height blade, in slot 5:

• Integrated LOM1 connection 1 connects to I/O module A1, port 5.

• Integrated LOM1 connection 2 connects to I/O module A2, port 5.

• Integrated LOM2 connection 1 connects to I/O module A1, port 21.

• Integrated LOM2 connection 2 connects to I/O module A2, port 21.

Dual-Port Mezzanine Cards

For a half-height blade in bay n:

• The integrated NIC connects to I/O module A1, port n and I/O module A2, port n.

• Mezzanine card B connects to I/O module B1, port n and I/O module B2, port n.

• Mezzanine card C connects to I/O module C1, port n and I/O module C2, port n.

For example, in a blade in slot 12, the integrated NIC connects to I/O module A1, port 12 and I/O module A2, port 12.
