Objectives

When you complete this module you will be able to:

Install NMS SS7 software

Install TX series hardware Verify that TX board is well installed

Configuring the Board(s)

The 'NMS TX CPs' Control Panel configuration applet is nolonger part of SS7.

First, run 'txcpcfg' and verify the bus and slot of theinstalled board(s). You should see the following:

2 4 UNDEFINED

For each UNDEFINED board, run txcpcfg

Ex. C:\ txcpcfg 2 2 1


5/46

Updating Board Firmware Usingtxflash

Update the on-board kernel with the latest firmware image

txflash - r oldfirmw.bin -w cpk3220.bin -b 1

r = read the old firmware image into filename specified

w = write filename image to flash memoryb = board number

Reset the board to execute the new firmware image

txreset -b 1
