Power-control button/power-on LED Ethernet icon LED 1 2 Information LED System-error LED Power-control button cover Ethernet port activity LEDs Locator button/locator LED The following controls and LEDs are on the operator information panel: v Power-control button cover: Slide this cover over the power-control button to prevent the server from being turned off accidentally. v Power-control button: Press this button to turn the server on and off manually. v Power-on LED: When this LED is lit and not flashing, it indicates that the server is turned on. When this LED is flashing, it indicates that the server is turned off and still connected to an ac power source. When this LED is off, it indicates that ac power is not present or the power supply or the LED itself has failed. Note: If this LED is off, it does not mean that there is no electrical power in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cords from the electrical outlets. v Ethernet-icon LED: This LED lights the Ethernet icon. v Ethernet activity LEDs: When these LEDs flash, they indicate that there is activity between the server and the network on the indicated port. v Locator LED: Use this LED to visually locate the server among other servers. You can use IBM Director to light this LED remotely or press the locator button to light the LED manually. This LED is also lit during startup. In multi-node configurations, when this LED flashes, it indicates that the server is the primary node. When this LED is lit continuously, it indicates that the server is a secondary node. v Locator button: Press this button to turn the locator LED on and off manually. In multi-node configurations, press this button to turn the locator LED on and off in all nodes in the configuration. v Information LED: When this LED is lit, it indicates that there is a suboptimal condition in the server and that light path diagnostics will light an additional LED to help isolate the condition. This LED and LEDs on the light path diagnostics panel remain lit until you resolve the condition or you press the remind button. v System-error LED: When this LED is lit, it indicates that a system error has occurred. An LED on the light path diagnostics panel is also lit to help isolate the error. Electrostatic-discharge connector: Connect an electrostatic-discharge wrist strap to this connector. Scalability LED: When this LED is lit, it indicates that an optional scalability key is installed in the server, which enables support for connecting the server to other servers to form multi-node configurations. 38 IBM System x3850 M2 and System x3950 M2 Types 7141 and 7233: Installation Guide

Power-control button cover
The following controls and LEDs are on the operator information panel:
v
Power-control button cover:
Slide this cover over the power-control button to
prevent the server from being turned off accidentally.
v
Power-control button:
Press this button to turn the server on and off manually.
v
Power-on LED:
When this LED is lit and not flashing, it indicates that the server
is turned on. When this LED is flashing, it indicates that the server is turned off
and still connected to an ac power source. When this LED is off, it indicates that
ac power is not present or the power supply or the LED itself has failed.
Note:
If this LED is off, it does not mean that there is no electrical power in the
server. The LED might be burned out. To remove all electrical power from the
server, you must disconnect the power cords from the electrical outlets.
v
Ethernet-icon LED:
This LED lights the Ethernet icon.
v
Ethernet activity LEDs:
When these LEDs flash, they indicate that there is
