Device Enabler Installation Instructions
Before using the Cisco Wireless Phone 840 with Cisco Unified Communications Manager Release 11.5, 12.5, 14, and later, the device enabler software must be installed on all Cisco Unified Communications Manager servers in the cluster.
Note: Choose an appropriate time to perform this task. As part of the Device Enabler COP file installation on the Cisco Unified Communications Manager publisher node, the database is updated and files are reloaded, which can cause high CPU utilization on the Cisco Unified Communications Manager subscriber nodes.
Perform the following procedure to install the device enabler for the Cisco Wireless Phone 840.

Cisco Manufacturing CA Certificates Installation Instructions
A new manufacturing certificate authority (CA) is being utilized for the Cisco Wireless Phone 840.
Until the new root and intermediate certificates are natively included in Cisco Unified Communications Manager, additional steps are required in order to trust the new Manufacturing Installed Certificate (MIC), which includes manually adding the root and intermediate certificates to the certificate chain.
1. To install the new Cisco Manufacturing CA certificates, first download the missing root and intermediate certificates from the externally available Cisco PKI website.
https://www.cisco.com/security/pki
The missing certificates to complete the chain of trust up to and including the root for the new MICs are below:
· Cisco Manufacturing CA III (cmca3) - Intermediate
· Cisco Basic Assurance Root CA 2099 (cbarc2099) - Root for Cisco Manufacturing CA III
2. Using your web browser, log in to the Cisco Unified Operating System Administration web page.
3. Under the Security menu, select Certificate Management.
4. Select Upload Certificate/Certificate Chain.
5. Select CallManager-trust for the Certificate Purpose, browse to the certificate, then select Upload.
Note: Repeat this step for all certificates on the Cisco Unified Communication Manager publisher only as the certificate will replicate to all other Cisco Unified Communication Manager nodes.
6. Select CAPF-trust for the Certificate Purpose, browse to the certificate, then select Upload.
Note: Repeat this step for all certificates on the Cisco Unified Communication Manager publisher only.
