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:
● 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.
● 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.
● 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.
● Fox: The bottom S5148F 1U 25 GbE back-end switch running 10 GbE SFP28 ports to the nodes. It is located below the
Hound switch in U16 of the EX300 rack.
