Chapter 12 Field-Replaceable Unit Guide
Replacing a Codec Unit—Part Number CTS-CODEC-PRI-G2 (Primary Codec) or CTS-CODEC-SEC (Secondary Codec)
Step 6 Remove the codec from the Display structure.
Step 7 Remove the L brackets from the codec.
See Chapter 8, “Assembling the Remaining Cisco TelePresence Elements” for additional information.
Step 8 Remove the cable management bar from the codec. Retain the bar and the screws.
See Chapter 8, “Assembling the Remaining Cisco TelePresence Elements” for additional information.
Step 9 Make a note of the MAC address of the new primary codec. The MAC address should be printed on a
sticker on the codec. You configure Cisco Unified Communications Manager to use the new MAC
address in the “Powering On the System” section on page 12-1.
Step 10 Attach the L-brackets and Cable management bar to the replacement codec.
See Chapter 8, “Assembling the Remaining Cisco TelePresence Elements” for additional information.
Step 11 Attach the new codec to the display structure front feet using the screws that you removed in Step 5.
Step 12 Turn the codec power switch to the On position.
Caution Make sure each PDU power switch is still in the Off position.
Step 13 Reattach the cables according to your temporary masking tape identification.
See Chapter 9, “Routing Power and Signal Cables” for additional information.
Step 14 Attach the cables to the cable management bar using tie wraps.
Step 15 If the replacement unit was the Primary codec, follow these steps to reset the MAC address in
Cisco Unified Communications Manager:
a. Open a browser on a computer connected to the network.
b. Access the Cisco Unified Communications Manager interface.
c. Change the MAC address for the Primary codec to its new address.
Step 16 Power on the system by completing the steps in the “Powering On the System” section on page 12-1.
Refer to the Cisco TelePresence System Administrator's Guide for your software release for more
information.
Step 17 Perform the Auto Adjust camera setup procedure. This sets the white balance to the correct levels. See
the “Setting Up the Cameras” section on page 10-6 for detailed instructions.
Note If you are replacing the primary codec, power it on and complete all steps before powering on the
secondary codecs. This prevents the secondary codecs from being affected by any software and
peripheral upgrades to the primary codec.
