This section covers the following hardware changes:

Cisco Unified Communications Manager does not support any other hardware changes, such as any form of field

For Uninterruptible Power Supply (UPS) integration, see the Cisco Unified Communications Manager release notes

In all hardware changes, any customer-provided hardware must be an exact match for what Cisco has certified to be
supported, i.e., exactly the same vendor, make, model, specs, and third-party part numbers.
