The WM-4T1i module has four T1 ports, using RJ-48 connectors, and two 10/100 Mbps autonegotiating
Ethernet ports, using standard RJ-45 connectors. The WM-4T1i 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-4T1i module supports T1 and
autonegotiation of 10BASE-T and 100BASE-T.
The default configuration of the WM-4Ti module is as follows:
• The four T1 ports allow 1.54 Mbps.
• The other two ports in autonegotiation mode allow 10 Mbps or 100 Mbps, and full duplex or
half-duplex operation.
WARNING!
To reduce the risk of fire, use only 26 AWG or larger telecommunication line cord.
You must ground the Alpine 3800 series chassis to ensure safe operation of the WM-4T1i module. For
information about grounding requirements for the Alpine 3800 series chassis, see "Grounding the
Alpine 3800 Series Chassis" on page 155.
