Page 10: Introduction
The WCM5100 has an internal LAN switch offering full wire-speed switching between ports. The WCM5100 uses MAC address filtering to filter all local traffic and only forward traffic destined for remote stations. Each of the WCM5100’s LAN ports support automatic cross-over switching and will therefore connect directly to a Hub/Switch/Router or PC End Station.
Page 11: Wcm5100 Rear Panel
User Manual 1.1 WCM5100 Rear Panel The WCM5100 device is a compact unit, as shown below, occupying half a shelf in a traditional 19inch rack. All power and data connectors and LED status indicators are accessible from the rear of the unit.
Page 12: Electro Magnetic Compatibility

Page 17: Rackmounting
User Manual 2.3 Rackmounting The WCM5100 is a standalone, desktop unit however it may be mounted in a standard 19 inch rack using the rack mounting kit, part number 80-05-256. To mount the WCM5100 in the 19 inch rack mount adaptor first remove the two M3x12 screws and washers from the rear panel of the unit.
Page 18: Wcm5100 Applications
In this application, the WCM5100 is operating with Traffic Isolation Disabled. In this mode, the WCM5100 acts as a simple, layer 2, 5 port switch with packetsswitched based on MAC address alone. The WCM5100 supports both local and remote switching, and forwarding over the WAN trunk.
