HUAWEI EM6 SL91 4-Port 2-Port RJ45 Fast Ethernet Gigabit Ethernet Interface Board

HUAWEI EM6 SL91 4-port 2-port RJ45 Fast Ethernet Gigabit Ethernet interface board


Product Description:

The functional version of an EM6 board is SL91.


Application:

EM6 boards can be used to receive and transmit GE/FE services or carry Multiprotocol Label Switching (MPLS) tunnels.

Receiving and Transmitting Ethernet Services

When OptiX RTN 980 uses Integrated IP microwave to transmit Ethernet services, EM6 boards can be used to receive and transmit GE/FE services. The FE/GE services may be from client equipment or Layer 2 networks.

Figure 1 Application scenario for EM6 boards to receive and transmit GE/FE services.


NOTE:

IF boards shown in the preceding figure must be common IF boards or XPIC IF boards working in native E1+Ethernet mode or native STM-1+Ethernet mode.

If required, two MPLS tunnels can be created on both the packet microwave network and local backhaul network so that PWE3 services are transmitted on multi-segment pseudo wires (MS-PWs) in end-to-end mode.

Service boards shown in the preceding figure can be Smart E1 processing boards or Ethernet interface boards.

System control boards can be CSHNA or CSHNU.


Functions and Features:

EM6 boards receive/transmit, process, and converge 4xGE+2xFE service signals. They also can receive/transmit 4xFE optical signals using FE SFP optical modules installed at their SFP ports.

Table 1 lists the functions and features supported by EM6 boards. EM6 boards implement Ethernet service functions by working with packet switching units on the system control, switching, and timing boards.


Table 1 Functions and features that EM6 boards support.

Function and FeatureDescription
Basic functionsReceives/Transmits GE/FE service signals, and processes these signals by working with the packet switching unit.
Port specificationsEthernet port

Provides six Ethernet ports.

Provides two unpluggable FE electrical ports.

Provides four unpluggable GE electrical ports or four SFP optical ports.

Supports the following types of SFP modules:

Dual-fiber bidirectional FE/GE optical module

Colored CWDM GE optical module (CWDM stands for coarse wavelength division multiplexing)

Single-fiber bidirectional FE/GE module

Backplane bus bandwidth

CSHN boards: 2.5 Gbit/s for slots 1 to 6 and 1 Gbit/s for slots 7 to 14

CSHNA boards: 2.5 Gbit/s for slots 1 to 2 and 1 Gbit/s for slots 3 to 14

CSHNU boards: 2.5 Gbit/s for slots 1 to 14

Switching mode

Centralized mode

NOTE:

When a board works in centralized mode, all Ethernet services carried on the board must be forwarded by the packet switching unit of the cooperating system control board.
