Figure 115: WM-4E1i module
The WM-4E1i module has four E1 ports, using RJ-48 connectors, and two 10/100 Mbps autonegotiating
Ethernet ports, using standard RJ-45 connectors. The WM-4E1i also has eight internal loopback ports
that allow you to configure bi-directional rate-limiting without tying up any of the external ports for
ingress rate shaping. Internal loopback ports are marked with the notation “iL” when displayed on the
command line or with ExtremeWare Vista Web access. The WM-4E1i module supports E1 and
autonegotiation of 10BASE-T and 100BASE-T.
The default configuration of the WM-4E1i module is as follows:
• The four E1 ports allow 2.048 Mbps.
• The other two ports in autonegotiation mode allow 10 Mbps or 100 Mbps, and full duplex or
half-duplex operation.
