Overview

Figure 5 shows a fully loaded FX2 chassis configured with two 10GbE PTMs. Four FC630 servers reside in
the front slots, each containing a quad-port converged network adapter (CNA). The PTMs reside in slots A1
and A2 in the back of the chassis.
This configuration requires eight uplinks from each PTM to the ToR switch, one for each server CNA port. If
an uplink fails, the corresponding CNA port goes down until the link is restored.

The same FX2 chassis with the two PTMs replaced by two FN410S IOMs is shown in Figure 6.
The four external ports on each FN410S are configured in a 40GbE LACP port channel connected to the ToR
switch. Anywhere from one to four uplinks can be used from each FN410S. The bandwidth of each LACP port
channel will equal the sum of the connected links.
Dell EMC recommends a minimum of two uplinks from each FN410S for redundancy. If an uplink fails, traffic
continues to flow on the remaining uplink(s) in the port channel without affecting connectivity of the server
CNAs.
