Dell ECS EX Series User Manual

EXF900 network cabling
The network cabling diagrams apply to the EXF900 appliance in a Dell EMC or customer-provided rack.
Customers connect to an EXF900 appliance by way of 25GbE ports on the front-end switches. For an EXF900 appliance, the
25GbE ports run at 25GbE. Customer configurations can include 25GbE front-end switches provided by Dell EMC or customers
may provide their own front-end switches.
To distinguish between the two front-end switches and the two back-end switches, each switch has a nickname:
● Hare: The top S5248F 1U 25GbE front-end switch. This switch runs 25GbE SFP28 ports to EXF900 nodes.
● Rabbit: The bottom S5248F 1U 25GbE front-end switch. This switch runs 25GbE SFP28 ports to EXF900 nodes.
● Hound: The top S5248F 1U 25GbE back-end switch running 25GbE SFP28 ports to the nodes.
● Fox: The bottom S5248F 1U 25GbE back-end switch running 25GbE SFP28 ports to the nodes.
