EX300 network cabling
The network cabling diagrams apply to the EX300 appliance in a Dell EMC or customer-provided
rack.
Customers connect to an EX300 appliance by way of 25 GbE ports on the front-end switches. For
an EX300 appliance, the 25 GbE ports run at 10 GbE. Customer configurations can include 25 GbE
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:
l
Hare: The top S5148F 1U 25 GbE front-end switch. This switch runs 10 GbE SFP28 ports to
EX300 nodes. It is located above the Rabbit switch in U22 of the EX300 rack.
l
Rabbit: The bottom S5148F 1U 25 GbE front-end switch. This switch runs 10 GbE SFP28 ports
to EX300 nodes. It is located below the Hare switch in U20 of the EX300 rack.
l
Hound: The top S5148F 1U 25 GbE back-end switch running 10 GbE SFP28 ports to the nodes.
It is located above the Fox switch in U18 of the EX300 rack.
