CHAPTER 2

CONNECTING TO THE NETWORK

2.1 INTRODUCTION

Installation of a Token Ring network typically requires more planning and explicit configuration than does a transparently-bridged Ethernet network. This chapter provides reference material and instructions that network administrators can use to configure the Token Ring modules.

For instructions on adding a Token Ring module to the ATX, see Chapter 6, Adding/Swapping Modules.

2.2 POWER-UP LED SEQUENCE

Power up the ATX and observe the LED sequence. It takes about 1 minute for the ATX to complete the power-up diagnostics. The ATX begins system diagnostics on the PPE (topmost module) and then individually on each installed module progressing from top to bottom.

The power-up LED sequence for the Token Ring module not attached to a network is as follows:

1.All LEDs flash.

2.The POWER and 16 LEDs remain on.

3.After a few seconds the PROC LED comes on.

4.The ST LEDs come on.

5.The RX and TX LEDs flash briefly.

6.The ST and PROC LEDs go off.

7.The PROC LED comes on and the 16 LEDs go off.

8.The TX and RX LEDs flash briefly.

9.The Token Ring module then boots with the PROC and PWR LEDs on.

10.All other LED activity beyond this point is a function of the configuration and connection of the ATX.
