I/O Module Port Mapping
The LOM and optional mezzanine cards are mapped to the I/O module ports
based on the following rules.
NOTE: The I/O port mappings in the following sections are applicable only to the
I/O Pass-Through Modules.
Full-Height Blades
Standard LOM (Dual-Port) Mapping
Each LOM has two port connections. For a full-height blade in bay n:
• Integrated LOM1, connection 1 connects to I/O module A1, port n .
Integrated LOM1, connection 2 connects to I/O module A2, port
n .
• Integrated LOM2, connection 1 connects to I/O module A1, port
n+8 .
Integrated LOM2, connection 2 connects to I/O module A2, port
n+8 .
For example, in a full-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 13
and LOM2 connection 2
connects to I/O module A2, port 13.
NOTE: Even though PowerEdge M610x is a full-height blade system, only one
network controller (LOM1) is available.
For PowerEdge M610x blade in bay n:
• The integrated NIC connects to I/O module A1, port n and I/O module
A2, port n
