Front-end and back-end switch connections
The front-end switch management ports connect to back-end switch ports via two CAT6 cable
and two 1GBaseT SFP.
These two cables and two SFP are used for Dell EMC switches. If you are deploying in a third party
rack with customer switches, or using customer switches in a Dell EMC rack, these two cables and
two SFP are not required.
The connection between the front-end switch ports and back-end switch ports are as follows:
l
Hare (FE2) to Fox (BE1)
l
Rabbit (FE1) to Hound (BE2)
The connections are shown with green lines in the following diagram.
