7970 Expansion Module all lights are red

Goal

The purpose of this document is to troubleshoot the 7970's expansion module with all lights are red. 

Problem

Expansion module all light up red.

  • CCM: CHI CM 6.
  • Phone Model: 7970
  • Expansion module: 7914

The phone had an old firmware(TERM70.6-0-2-0S)

It couldn't upgrade directly to the CHI CM 6 default load for 7970's(SCCP70.8-5-3S).

The old firmware doesn't work with the side car.

Solution

  1. Upgrade the phone to version : SCCP70.8-3-1S.
  2. Then upgrade to Version: SCCP70.8-4-4S.
  3. Then remove the load specified in CCM so it would upgrade to the default version: SCCP70.8-5-3S
