3–7 Installing the DEC WANrouter 90
NOTE
Figure 3–4 shows the T-connector terminated using a
50-ohm terminator. The 50-ohm terminator is replaced
by a cable if the router is not at the end of a cable seg-
ment. The cable segment must be terminated by 50-ohm
terminators at both ends unless a DEMPR or a DESPR is
used. Where a cable segment is terminated in a DEMPR
or a DESPR at one end only, the opposite end needs to
have a 50-ohm terminator.
3.2.3 Completing the Standalone Router Installation
To complete the standalone router installation, perform the following steps:
1. Connect the H3199 loopback connector to the router’s 50-pin male D-con-
nector.
2. Plug the external power supply connector into the DEC WANrouter 90’s
power connector.
3. Attach the power cord to the power supply (if you are using an international
power supply).
4. Plug the power supply or power supply cord into a working ac outlet.
5. With the power applied to the DEC WANrouter 90, the unit’s Power LED is
lit and the router starts its self
-
test. The self-test takes approximately one min-
ute to complete. Refer to Section 3.4 for information about running the self
-
test.
