Dell EMC S5148F switch
The EX500. EX300, and EX3000 appliances all use the Dell EMC S5148F for the front-end pair of switches and for the pair of
back-end switches. Note that customers have the option of using their own front-end switches instead of the Dell EMC S5148F
switches. The Dell EMC S5148F switches are required for the back-end pair.

Front-end switch pair
Dell EMC offers an optional HA pair of front-end 25 GbE S5148F switches for customer network connection to the rack. It
has two 100 GbE virtual link trunking (VLT) cables per HA pair. These switches are called the Hare (FE2) and the Rabbit (FE1)
switches.
Customers can use their own front-end switch pair (10/25 GbE for EX300 and 25 GbE for EX500 and EX3000) using the Dell
EMC Request for Product Qualification (RPQ) process. In this case, the customer must provide the appropriate VLT cables,
SFPs, or external connection cables.
CAUTION:
It is required to have connections from the customer's network to both front-end switches (rabbit
and hare) in order to maintain the high availability architecture of the ECS appliance. If the customer chooses
not to connect to their network in the required HA manner, there is no guarantee of high data availability for the
use of this product.
