Quarter-Height Blades

A quarter-height blade supports one mezzanine card. The mezzanine card slot supports Fabric B or Fabric C, depending
on the slot in the sleeve where the blade is installed.
I/O Module Port Mapping—Full-Height Blades
NOTE: The I/O port mappings in the following sections are applicable only to the I/O Pass-Through Modules.

Standard LOM (Dual-Port) Mapping

Each LOM has two port connections. For a full-height blade in bay

:
• 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.
• Integrated LOM1 connection 2 connects to I/O module A2, port 5.
• Integrated LOM2 connection 1 connects to I/O module A1, port 13.
• Integrated 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.
