DEC WANrouter 90 Owner’s Manual
Hardware
Ensure that the ThinWire Ethernet LAN is in place and operable.
Ensure that a DEChub 90 Ethernet backplane is installed and operable; or
if this is a standalone installation, ensure that arrangements have been
made to connect the router’s Ethernet port to a suitable Ethernet interface
device (a DEMPR, a DESPR or a ThinWire segment), and that an appro-
priate ac power source is within 1.6 m (5.5 ft) of the router.
Ensure that the appropriate synchronous or asynchronous device (a mo-
dem, personal computer, or host) is ready for connection to the router’s
serial port.
Electrical and Environmental Requirements
Ensure that the electrical and environmental requirements are within the
ranges described in the DEC WANrouter 90 specifications listed in
Chapter 1.
Cabling Requirements
Ensure that the required adapter cable for connecting the synchronous or
asycnhronous device to the DEC WANrouter 90’s 50-pin port has been
obtained. Note that this cable is not included in the shipment. Refer to
Appendix A for information about the type of cables to use. Refer to Ap-
pendix B for information about ordering cables.
Ensure that appropriate types and lengths of cable are available for con-
nection to the Ethernet (if this is a standalone installation).
Service
Make sure the (optional) service contracts are in place. Call your Digital
sales representative for information on available hardware and software
services to support the DEC WANrouter 90.
