Chapter 5: Advanced Serverboard Setup
5-10 Onboard Indicators
JLAN LEDs
The Gigabit Ethernet LAN ports (lo- cated beside the VGA port) each have two LEDs. One LED indicates activity while the other LED may be green, amber or off to indicate the speed of the connection. See table at right for the functions associated with the con- nection speed LED.
Unit Identifier
A Unit Identifi er (UID) feature on the server makes it easy to locate the unit in a large stack. While servicing the system, if you fi nd you need to work on the other side of the unit, push the UID button (located on the far left of the control panel on the front and to the right of the VGA port on the rear of the chassis) to illuminate an LED on the other side of the chassis. When you walk around to the other side of the rack, the unit will then be easy to spot. The LED will remain on until the UID button is pushed again. The rear chassis UID is a button and LED in one. The front control panel includes a separate LED and button.
