Locating Front Panel Components and LEDs

Front Panel Components

FIGURE 1-1 shows the system components that you can access from the front panel. In the figure, the system door is opened.

For more detailed information about each of the front panel components, refer to the Netra 440 Server Product Overview.

TABLE 1-1 lists the front panel components The table indicates whether the components are hot-swappable or cold-swappable, and whether they can be removed from the front of the system or through the top of the system.

Front Panel LEDs

Several front panel LEDs provide general enclosure status, alert you to system problems, and help you to determine the location of system faults.

During system startup, the LEDs are toggled on and off to verify that each one is working correctly. LEDs located on the front panel work in conjunction with specific fault LEDs. For example, a fault in the power supply subsystem illuminates the power supply Service Required LED on the affected power supply, as well as the system Service Required LED. Since all front panel status LEDs are powered by the system's standby power source, fault LEDs remain lit for any fault condition that results in a system shutdown.

FIGURE 1-2 shows the LEDs that are accessible from the front. In the figure, the system door is opened.

  FIGURE 1-2 Front Panel LEDs

This figure shows the front panel LEDs. [ D ]

Enclosure Status LEDs

At the top left of the system as you look at its front are three enclosure status LEDs. The System Activity LED and the system Service Required LED provide a snapshot of the overall enclosure status. The Locator LED helps you to quickly locate a specific system even though it may be one of numerous systems in a room. The Locator LED is at the far left in the cluster, and is lit by command from the administrator.

  FIGURE 1-3 Enclosure Status LEDs

This figure shows the location of the enclosure status LEDs located along the top left corner of the system.[ D ]

Each enclosure status LED has a corresponding LED on the back panel.

The enclosure status LEDs operate as described in the following table.

Description

Locator

This illustration shows the Locator LED icon. 

This white LED is lit by a Solaris OS command or by ALOM software to locate a system. See the Netra 440 Server System Administration Guide for more information.

Service Required

This illustration shows the Service Required LED icon. 

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 Activity

This illustration shows the System Activity LED icon. 

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


Hard Drive Status LEDs

Each hard drive has its own status LEDs directly above the drive.

1 (TableFootnote) NC state is the normally closed state. This state represents the default mode of the relay contacts in the normally closed state.
2 (TableFootnote) NO state is the normally open state. This state represents the default mode of the relay contacts in the normally open state.
3 (TableFootnote) The user can shut down the system using commands such as init0 and init6. This does not include the system power shutdown.
4 (TableFootnote) Based on a determination of the fault conditions, the user can turn the alarm on using the Solaris platform alarm API or ALOM CLI. For more information about the alarm API, see the Netra 440 Server System Administration Guide and for more information about ALOM CLI, see the Sun Advanced Lights Out Manager Software User's Guide for the Netra 440 Server.
