Installation
This product is a flexible Ethernet Bridge/Router that may be configured to service Local
Area Networks and Wide Area Network connections over leased lines, ISDN circuits, and
frame relay permanent virtual circuits. The router supports two independent LANs plus one
WAN interface or a single LAN plus two WAN interface modules (if two ISDN BRI
modules are installed, this will provide 4 WAN links)
PPP ISDN units provide bridging, IP/IPX routing, and compression over a PPP ISDN
connection and support an ISDN BRI interface via an integral ISDN-ST or ISDN-U link
module. The ISDN BRI interface supports two 64 Kbps B-channels.
PPP Lease line units provide bridging, IP/IPX routing, and compression and support one
or two physical wide area network (WAN) links that may operate at speeds up to 2.048
Mbps.
Frame Relay units provide bridging and IP/IPX routing and support 1 to 128 Permanent
Virtual Circuit (PVC) across two physical wide area links running RAW 1490 or
encapsulated PPP.
The following instructions provide a quick set-up guide for installation of the router:
Unpack the Router
Rough handling during shipment can damage electronic equipment. As you unpack the
bridge/router, carefully check for signs of damage. If damage is suspected, contact the
shipper. Save the box and all packing material to protect the bridge/router should it ever
need to be moved or returned for service.
Check the packing slip that identifies the components and the LAN connector.
Select a Site
Place the bridge/router in a well ventilated area. The site should maintain normal office
temperature and humidity levels. Air vents located on the sides of the bridge/router must
have approximately one inch / 2.5 centimeters of clearance from any object.
