Netfinity 1000 - Controls and indicators, and status indicators

Applicable to: World-Wide

Source: Hardware Maintenance Manual

Controls and indicators
The most commonly used controls and status indicators are on the front of the server.

Server controls


Power Switch: Press this switch to turn the server on or off.

Attention Do not turn off the server if a drive in-use light is on. This might damage the information stored on a hard disk or on a diskette.

When the power is on, there is a period of time during the power-on self-test (POST), a short test that occurs when the server is turned on, when a single touch of the power switch will not turn off the power. If power must be turned off during POST, press and hold the power switch for 5 seconds or disconnect the power cord. After POST, the power switch works normally, unless the server is in a hang condition. If the server is in a hang condition, press and hold the power switch until the power turns off.

CD-ROM Eject/Load Button: Push this button to release a CD from the CD-ROM drive. See CD-ROM drive for additional information about the CD-ROM drive controls and indicators.

Diskette Eject Button: Push this button to release a diskette from the diskette drive.

Status indicators:
The following illustration identifies the indicators located on the front of the server.



Power-On Light: This light comes on when you turn on the server by pressing the power switch.

Hard Disk Drive In-Use Light: This light comes on when the server is accessing a SCSI hard disk drive. If this light remains illuminated, it might indicate that either the SCSI bus or the system microprocessor has stopped.

Ethernet Activity Light: This light comes on when the Ethernet controller is transmitting data to or receiving data from another system in the network.

Ethernet Diagnostic LED: The server contains a diagnostic light-emitting diodes (LEDs) for the Ethernet connector located on the rear panel of the server.

• When the green LED is on, it indicates that the Ethernet controller is connected to a hub or switch and is receiving link pulses. This LED is also known as the Link OK light.
• When the amber LED is on, it indicates that the Ethernet network is operating at 100 Mbps. When this LED is off, it indicates that the Ethernet network is operating at 10 Mbps.

CD-ROM Drive In-Use Light: This light comes on when the CD-ROM drive is accessed.

Diskette Drive In-Use Light: This light comes on when the diskette drive is accessed.
