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 (PowerEdge 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.

LOM2 connection 1 connects to I/O module A1, port 21 and LOM2 connection 2 connects to I/O module A2, port 21.
