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 (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. For more information, see
"Port Auto-Disablement in Quad-Port Network Daughter Card (PowerEdge M710HD
Only)" on page 53.
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.
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.
