The following
I/O module port mapping options are available on the four-bay chassis
configuration that supports up to four half-width compute sleds.
NOTE: In the four-bay PowerEdge
FX2s configurations that support storage sleds mapped to compute sled(s),
the I/O module ports are mapped only to the compute sled(s). If storage
sleds are installed, the corresponding ports on the I/O modules mapping
to these slots are not active.
Figure 1. I/O module port
mapping—half-width compute sleds with dual port NDC
A half-width compute sled that is configured with dual
port Network Daughter Card (NDC) is mapped to a single port on each
I/O module. The following table lists the compute sleds and the ports
to which they are mapped.
Table 1. I/O module port
mapping—half-width compute sleds (dual port NDC)In a four-bay chassis, the half-width compute sled configured
with dual-port NDC populated in bay 1 is mapped to port 1 on both
IO Module A1 (Top) and IO Module A2 (Bottom). In a four-bay chassis,
the half-width compute sled configured with dual-port NDC populated
in bay 2 is mapped to port 3 on both IO Module A1 (Top) and IO Module
A2 (Bottom). In a four-bay chassis, the half-width compute sled configured
with dual-port NDC populated in bay 3 is mapped to port 5 on both
IO Module A1 (Top) and IO Module A2 (Bottom). In a four-bay chassis,
the half-width compute sled configured with dual-port NDC populated
in bay 3 is mapped to port 7 on both IO Module A1 (Top) and IO Module
A2 (Bottom).

Figure 2. I/O module port
mapping—half-width compute sleds with quad port NDC/network output
A half-width compute sled configured
with quad-port NDC is mapped to two ports on each I/O module.
A half-width compute sled with four compute nodes is
configured with a quad-port network output, which is mapped to two
ports on each I/O module. The network traffic from the nodes in the
compute sled to the I/O modules in the enclosure is routed through
a network switch that is embedded on the compute sled system board.
For more information, see the Dell PowerEdge FM120x4 Owner's Manual at Dell.com/poweredgemanuals.
The following
table lists the compute sleds and the ports to which they are mapped.
Table 2. I/O module port
mapping—half-width compute sleds (quad port NDC/network output)In a four-bay chassis, the half-width compute sled configured
with quad-port NDC populated in bay 1 is mapped to ports 1, 2 on both
IO Module A1 (Top) and IO Module A2 (Bottom). In a four-bay chassis,
the half-width compute sled configured with quad-port NDC populated
in bay 2 is mapped to ports 3, 4 on both IO Module A1 (Top) and IO
Module A2 (Bottom). In a four-bay chassis, the half-width compute
sled configured with quad-port NDC populated in bay 3 is mapped to
ports 5, 6 on both IO Module A1 (Top) and IO Module A2 (Bottom).
In a four-bay chassis, the half-width compute sled configured with
quad-port NDC populated in bay 3 is mapped to ports 7, 8 on both IO
Module A1 (Top) and IO Module A2 (Bottom).
