Ethernet Interface; Software Switches; Selecting The Thickwire/Thinwire Or Twisted Pair Ports - Digital Equipment AlphaStation 500 Series User Information

Ethernet Interface

The AlphaStation 500 Series system uses a Media adapter unit (MAU) card to support
Ethernet connections. This module provides for ThinWire, or twisted-pair Ethernet
operation. Refer to Figure 3-3.

Software Switches

Software switches which must be set properly from the console mode. To determine the
system setup, type:
show ewa0
at the >>> prompt. To set the proper mode, type:
set ewa0 x
where x is equal to either twisted-pair operation (which looks like phone connector) or
BNC which is the ThinWire (round coaxial connector).

Selecting the ThickWire/ThinWire or Twisted Pair Ports

Open VMS or Digital UNIX AlphaStation 500 series systems must be told to use the
appropriate Ethernet port.
Change the port types by using the following SRM console commands:
>>> set ewa0_mode AUI
>>> set ewa0_mode twisted
After changeing the port, type >>> init or power cycle the machine. The Windows NT
operating system auto-senses which network port is connected.
