SSN3EFS4 Is Huawei OSN 1500 EOS Board
Huawei OSN 1500 EOS Board SSN3EFS4 Overview
The EFS4 is available in three functional versions, namely, N1, N2 and N3. The difference between the three versions is their different maximum uplink bandwidths. The N1EFS4 and N2EFS4 are discontinued.
The SSN3EFS4 is used to transmit/receive Ethernet services, manage bandwidths, and realize Layer 2 switching of Ethernet services.
EFS4 boards support the Layer 2 switching, MPLS, and broadcast functions.
The EFS4 consists of the Ethernet access module, network processor module, mapping module, interface converting module, logic and control module, clock module, and power module.
The front panel of the EFS4 has indicators, interfaces, and a bar code.
The EFS4 does not have any jumpers or DIP switches that are used for board settings.
The EFS4 must be installed in a valid slot in the subrack. Otherwise, the EFS4 cannot work normally.
