Quick Start

To install and begin using your DECserver 90L is simple. It does not

require any programming or other assistance from system management.

After unpacking the unit:

1. Plug the power supply in a working AC outlet and plug the power

connector from the power supply in to your DECserver 90L.

The green power LED turns on to indicate DC power is getting to the

unit. The green self-test turns on to indicate that the unit successfully

completed its internal self-test. The self-test takes approximately ﬁve

seconds to complete.

2. Connect the unit to a properly terminated ThinWire Ethernet.

The green network LED turns on to indicate a good connection.

Overview 1–3

3. Connect a working terminal to one of the terminal ports. Refer to

Table 1–1 for supported terminal characteristics.

4. Turn the power on to the terminal and press Return twice to get the

DECserver 90L prompt (->).

Pressing Return twice causes the green activity LED to blink and

automatically sets the port’s baud rate.

5. Enter the name of the network node you want to connect to and press

Return . The DECserver 90L will display a string of dots ‘‘.....’’, one per

second, until the connection is made.

For more detailed information on installing and using the DECserver 90L

refer to Chapter 2, Installation and Chapter 3, Operation of this manual.
