X.25 PAD Adapter Module Supplement

118456-A Rev 02

Installing the Breakout Box

To support X.25 PAD applications, the ARN requires an X.25 PAD adapter

module and an attached breakout box that supplies eight additional serial ports.

Both items are part of the ARN X.25 PAD upgrade kit.

You install the X.25 PAD adapter module in one of the two ARN WAN adapter

module slots (Figure 1)

. See Installing and Operating BayStack ARN Routers.

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

• Place the box on top of the ARN (Figure 2)

. Attach the rubber feet that came

in the upgrade kit to the four raised areas on the bottom of the breakout box.

• Install the box above the ARN in a standard equipment rack. Attach the

breakout box to the rack using the screws and cagenuts supplied in the

upgrade kit.
