June 2006 Installation Guide

Chapter 5

Activation and Testing

5.1 Introduction

This chapter describes how to power up the MTAS-192 shelf and verify that it is

operating correctly, after all required physical installation of the MTAS shelf, circuit

packs, and associated cabling has been completed as described in the preceding

chapters.

5.2 Powering the MTAS-192

Apply power to the MTAS shelf by inserting the fuse corresponding to the MTAS shelf at

the Power Distribution Block at the top of the rack. (See Appendix A MTAS

Specifications for fuse requirements). For redundant power, remember to insert the

corresponding A and B feed fuses.

5.3 Validating Operation of Control Cards and Line Cards

After applying power to the MTAS-192 shelf, the Light Emitting Diodes (LEDs) on the

card faceplates should behave as listed in Table 12. Figure 33 and Figure 34 show

flowcharts for validating operation of these cards.

Table 12: LED Operation after Successful Power Up

Cards LEDs LED Action After Power Up

PWR/Status

Immediately light solid red, then after a few seconds

light solid green.

Master

Shelf

TAPs 1 and 2

Immediately light solid red, then after a few seconds

light solid green.

PWR/Status

Immediately flash red for several seconds, then light

solid amber. This LED will remain amber until it is

discovered by the master shelf (typically 30 seconds),

at which time it will light solid green and each line card

will be then be restarted, processing from left to right,

with its PWR/Status LED lighting – flashing amber for a

few seconds, then solid green.

Control Cards

Binary ID Indicates configured chassis ID.

Line Cards PWR/Status

Flicker amber until the card can read a valid chassis ID,

then light solid green.
