`The ``set`` ``lcd_settings`` ``hwident`` `command enables and disables the UID (unit identification) button on Trinzic appliances. When you enable the UID button, the LCD panel on the front panel blinks and the UID LED on the rear panel glows blue. In a rack environment, the UID feature allows you to easily identify the appliance when moving between the front and rear of the rack.

# Syntax

`set lcd_settings hwident {off | on}`

| **Argument** | **Description** |
| --- | --- |
| off | Disables the UID feature on the Trinzic appliance. |
| on | Enables the UID feature on the Trinzic appliance. |

# Examples
