109 Dell EMC PowerEdge MX SmartFabric Configuration and Troubleshooting Guide
Dell EMC Networking MX5108n
The following MX5108n components are labeled in Figure 101:
1. Luggage Tag
2. Storage USB Port
3. Micro-B USB console port
4. Power and indicator LEDs
5. Module insertion/removal latch
6. One QSFP+ port
7. Two QSFP28 ports
8. Four 10GbE BASE-T ports
NOTE: While the examples in this guide are specific to the MX9116n FSE and MX7116n FEM, the use of two
MX5108n switches in a single chassis is supported for the solutions shown. Cabling options for the MX5108n will
differ from the MX9116n/MX7116n as shown in the
Dell EMC PowerEdge MX IO Guide.
A.8 PowerEdge MX7000 Fabrics I/O slots
The PowerEdge MX7000 chassis includes two I/O fabrics: Fabric A and Fabric B. The vertically aligned
compute sleds in slots one through eight connect to the horizontally aligned IOMs in slots A1, A2, B1, and B2.
This orthogonal connection method results in a midplane-free design and allows the adoption of new I/O
technologies without the burden of having to upgrade the midplane.
The MX740c supports two mezzanine cards, and the MX840c supports four mezzanine cards. Each
mezzanine card connects to a pair of IOMs installed in the corresponding fabric slots as shown in Figure 102.
For example, port one of mezzanine card A1 connects to fabric slot A1, containing an MX9116n FSE for
example (not shown). Port two of mezzanine card A1 connects to fabric slot A2, containing an MX7116n FEM
for example (not shown).
