A Cisco TelePresence EX90 endpoint is not registering successfully, and the endpoint IP address is not known. What is the proper method to obtain the current IP address of the device?

Rebooting the device to watch the screen during boot is unreliable and may not display the IP address long enough or at all depending on firmware configuration.

Telnet requires an IP address as its destination - it cannot connect using a MAC address, making this method technically invalid.

The Cisco TelePresence Remote can navigate some on-screen menus but does not provide a direct or reliable path to displaying the current IP address compared to the dedicated Touch Control interface.

Connecting a computer to the NIC on the EX90 and enabling DHCP would only configure the computer's network interface, not reveal the EX90's existing IP address.

The Cisco TelePresence Touch Control system menu allows an administrator to navigate to the system information or diagnostics section, where the current IP address is displayed. This method works regardless of whether the endpoint is successfully registered, making it the proper approach when the IP is unknown. No prior knowledge of the address or network connectivity from a separate device is required to use the Touch Control locally.
