I/O Module Port Mapping—Quarter-Height Blades
NOTE: Up to four quarter-height blades are installed in a sleeve. This section includes all four blades when
referring to a sleeve.

Standard LOM (Dual-Port) Mapping

Each LOM has two port connections. For a sleeve in enclosure slot
n
:
•Blade a LOM connection 1 connects to I/O module A1, port
n
, and connection 2 connects to I/O module A2, port
(n+16)
.
•Blade b LOM connection 1 connects to I/O module A2, port
n
, and connection 2 connects to I/O module A1, port
(n+16)
.
•Blade c LOM connection 1 connects to I/O module A1, port
(n+8)
, and connection 2 connects to I/O module A2,
port
(n+24)
.
•Blade d LOM connection 1 connects to I/O module A2, port
(n+8)
, and connection 2 connects to I/O module A1,
port
(n+24)
.
For example, in a sleeve in enclosure slot 8:
•Blade a LOM connection 1 connects to I/O module A1, port 8, and connection 2 connects to I/O module A2, port
24.
•Blade b LOM connection 1 connects to I/O module A2, port 8, and connection 2 connects to I/O module A1, port
24.
•Blade c LOM connection 1 connects to I/O module A1, port 16, and connection 2 connects to I/O module A2, port
32.
•Blade d LOM connection 1 connects to I/O module A2, port 16, and connection 2 connects to I/O module A1, port
32.
