ACU not recognized by the primary codec or is disconnected which is causing issues with the light shroud, or when running hardware setup for ACU, getting error message that the primary codec cannot communicate with ACU.
Auxiliary Control Unit
The auxiliary control unit provides the ability to conserve energy by powering the Cisco TelePresence System lights on and off.
There is one power inlet, five controlled power outlets, and one power outlet that is not controlled (unswitched).
In addition, there are two serial ports and an incoming and outgoing Ethernet connection that allows you to control peripheral items.
The auxiliary control unit is controlled by your CTS Administrator and can be configured to:
Turn the CTS lights on during a Cisco TelePresence call and turn the lights off after the call completes, or to stay on for a period of time after a call completes
Turn the CTS lights on according to a configured time schedule
Leave the CTS lights on continuously
Conditions / Environment
Faulty hardware and/or incorrect cabling and/or firmware rev can cause issues with the ACU which can affect the light shroud activation.
CLI command output from codec for "admin: show hardware all"
Show hardware all: (partial) (if ACU not showing up will see):
Aux Control Unit Model : INFO:ACU disconnected
Aux Control Unit Version : INFO:ACU disconnected
Aux Control UDI Vid : INFO:ACU disconnected
Aux Control UDI Pid : INFO:ACU disconnected
Aux Control UDI Sn : INFO:ACU disconnected
Or if ACU recognized will see:
Control Unit Model : Auxiliary Control Unit
Aux Control Unit Version : System Firmware: 01.30
Aux Control Unit UDI Vid : V01
Aux Control Unit UDI Pid : CTS-LIGHT-CTRL Aux Control Unit UDI Sn : VLX13100PWB or checking the CTS logs check nv/log/capture/showsysinfo.log
Working unit will appear as follows:
Unit not working or missing or with cabling issue
Aux_Control_Unit_Model=INFO:ACU is disconnected
Aux_Control_Unit_Ver=INFO:ACU is disconnected
Aux_Control_Unit_UDI_Vid=INFO:ACU is disconnected
Aux_Control_Unit_UDI_Pid=INFO:ACU is disconnected
Aux_Control_Unit_UDI_Sn=INFO:ACU is disconnected
Troubleshooting requires access to the CTS GUI as well as more importantly the CLI of the codec
Power Off / Power On of the ACU (Check for powe switch LED)
Reset button back of ACU ( Reset button is on the back of the ACU between the Ethernet ports and Serial interfaces)
Installation troubleshooting Cabling:
Ensure Main Power cable for ACU is connected to its own electrical circuit and NOT connected into a PDU
Ensure that the light shrouds are connected into the ACU and NOT directly into PDUs
Ensure Ethernet cable connects ACU (Ethernet Port 2) to Master Codec (Auxiliary Ethernet Port / Document Camera Port)
CTS GUI Troubleshooting:
See if you can turn the light segments on / off from System
Reset ACU from System Administration Web GUI
The Firmware for the ACU can be checked to be out of date which is likely causing this issues with the light shroudas well
The ACU firmware should be "1.30" for the firmware for the ACU but if it is showing to be 1.27: Aux_Control_Unit_Model=Auxiliary Control Unit Aux_Control_Unit_Ver=System Firmware: 01.27 this is then outdated firmware.
Go into the CLI and issue the following to force the firmware upgrade:
“admin:set upgrade auxilary-control force reboot”
admin: set upgrade firmware auxiliary-ctrl force reboot”
Setting forced firmware upgrade
Admin: show upgrade detail (should be 1.30 for Aux control)
