SUPER MICRO Computer X9DRG-HTF, X9DRG-HF user manual Unit Identifier Switch, UID LED LE4

Chapter 2: Installation

Unit Identifier Switch

A Unit Identifier (UID) Switch and two LED In- dicators are located on the motherboard. The UID Switch is located next to LAN2 port on the backplane. The Rear UID LED (LE4) is located next to the UID Switch. The Front Panel UID LED is located at pins 7/8 of the Front Control Panel at JF1. Connect a cable to pin 8 on JF1 for Front Panel UID LED indication. When you press the UID switch, both Rear UID LED and Front Panel UID LED Indicators will be turned on. Press the UID switch again to turn off both LED Indicators. These UID Indicators provide easy identification of a system unit that may be in need of service.

Note: UID can also be triggered via IPMI on the motherboard. For more information on IPMI, please refer to the IPMI User's Guide posted on our website @ http://www.supermicro. com.
