ONNECTIONS
The ECS3510-28F switch provides 24 downlink fiber ports and four combination
SFP/RJ-45 uplink ports. The 1000BASE-T ports can provide a trunked high-
bandwidth connection to a core switch or router at the CO. Besides balancing the
load across each port in the trunk, the additional port provides redundancy by
taking over the load if the other port in the trunk fails.
The figure below illustrates the ECS3510-28F connecting to a core switch with
UTP cable.
