This appendix gives information on the Netra 440 server LEDs. All of the information in this appendix is related directly to instructions in this guide.
Enclosure Status LEDs
As you install your Netra 440 server, be aware of several enclosure status LED indicators on both the front and back panels. These indicators provide general enclosure status, alert you to system problems, and help you to determine the location of system faults.
At the top left of the server front are three general enclosure status LEDs. Two of these LEDs, the system Service Required LED and the System Activity LED, provide a snapshot of the overall enclosure status. One LED, the Locator LED, helps you to locate a specific system quickly, even though it might be one of many systems in a room. The Locator LED is lit by command from the administrator. For instructions, refer to the Netra 440 Server Diagnostics and Troubleshooting Guide (817-3886-xx).
Other LEDs located on the front of the server work in conjunction with specific fault LED icons. For example, a power supply fault illuminates the associated power supply Service Required LED and the system Service Required LED. Since all front panel status LEDs are powered by the server's 5-volt standby power source, fault LEDs remain lit for any fault condition that results in a system shutdown. Locator, Service Required, and System Activity LEDs are also found at the upper-left corner of the back panel.
The enclosure status LEDs operate as described in the following table.

|
This white LED is lit by Solaris OS command, by Sun Management Center software, or by Sun Remote System Control software, to locate a system. See the Netra 440 Server System Administration Guide for more information
|
|
Service Required
|
|
This amber LED lights when system hardware or software has detected a system fault. This LED lights for any faults or failures detected in the following areas:
- Motherboard
- CPU/memory module
- DIMM
- Hard drive
- Fan trays
- Power supply
In addition to the system Service Required LED, other fault LEDs might also be lit, depending on the nature of the fault. If the system Service Required LED is lit, check the status of other fault LEDs on the front panel to determine the nature of the fault. See the Netra 440 Server Diagnostics and Troubleshooting Guide for more information.

System Active
|
|
This green LED lights when the ALOM detects that Solaris OS is running.

Alarm LEDs
The alarm LEDs are located at the front of the system, along the left side of the front cover.
The dry contact alarm card has four LED status indicators that are supported by ALOM. Information about the alarm indicators and dry contact alarm states is provided in TABLE B-2. For more information about alarm indicators, refer to the Sun Advanced Lights Out Manager Software User's Guide for the Netra 440 Server (817-5481-xx). For more information about an API to control the alarm indicators, refer to the Netra 440 Server System Administration Guide (817-3884-xx).
