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 more information, see
"Port Auto-Disablement in Quad-Port Network Daughter Card (M710HD Only)" on
page 49.
For example, in a half-height blade in slot 5, integrated LOM1 connection 1
connects to I/O module A1, port 5 and LOM1 connection 2 connects to I/O
module A2, port 5. LOM2 connection 1 connects to I/O module A1, port 21
and LOM2 connection 2 connects to I/O module A2, port 21.
