Polycom Sidecar/Expansion Module Continuously Reboots

Symptom

After connecting a Polycom Sidecar or Expansion Module to the physical device, sidecar boots up continuously. The desk phone is connected and working properly yet the sidecar does not come up with the lines configured in Account Manager or Admin Console. Rebooting desk phone and side car it do not fix the issue either.

Applies To

• Account Manager
• Admin Console
• Polycom desk phones
• Side car/ Expansion Module

Resolution

Replace the desk phone the sidecar is connected to as the AUX port might be faulty.

Cause

Faulty/defective AUX port on the desk phone.
