Information LED panel
The following illustration shows the server information panel.
System power light: When this green light is on, system power is present in the
server. When this light flashes, the server is in standby mode (the system power
supply is turned off and AC current is present). When this light is off, either a power
supply, AC power, or a light has failed.
Note: If this light is off, it does not mean there is no electrical current present in the
server. The light might be burned out. To remove all electrical current from
the server, you must unplug the server power cords from the electrical
outlets.
Hard disk drive activity light: This green light is on when there is activity on a hard
disk drive.
Ethernet-link status light: When this green light is on, there is an active connection on
the Ethernet port. The Ethernet link-status light is also located on the Ethernet (RJ-45)
connector on the rear of the server.
Ethernet speed light:
When this green light is on, the Ethernet speed is 100 Mbps.
When the light is off, the Ethernet speed is 10 Mbps.
Ethernet transmit/receive activity light: When this green light is on, there is activity
between the server and the network. The Ethernet transmit/receive activity light is
also located on the Ethernet (RJ-45) connector on the rear of the server.
Information light: When this amber light is on, the server power supplies are
nonredundant or some other noncritical event has occurred. Check the diagnostic
panel for more detailed information.
System error light: This amber light is on when a system error occurs. A light on the
diagnostics LED panel will also be on to further isolate the error. (For more
information, see the User’s Reference on the IBM Netfinity Documentation CD.)
