Nortel Networks 114200-E manual To connect X.25 PAD services

Installing and Operating Passport ARN Routers

To connect X.25 PAD services:

1.Position the X.25 breakout box above the ARN in one of the following ways:

•Attach the rubber feet that came in the shipping container to the four raised areas on the bottom of the breakout box chassis; then, place the box on top of the ARN (Figure 1-18).

•Using the screw holes on the sides of the breakout box, install the box above the ARN in a standard equipment rack. For information about rack-mounting the ARN, see “Rack-Mounting the ARN” on page 1-6.

2.Connect the DB-60 cable on the breakout box to the X.25 PAD connector on the installed module (Figure 1-18).
