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.

FIGURE 1-1 Front Panel Components

This figure shows the system components accessible from the front panel.

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.

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.

TABLE 1-2 Enclosure Status LEDs
Name	Icon	Description
Locator		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 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 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.

FIGURE 1-4 Hard Drive Status LEDs

This figure shows the location of the hard drive LEDs located along the top right section of the system, above each hard drive.

[ D ]

The following table describes the hard drive LEDs.

TABLE 1-3 Hard Drive LEDs
Name	Icon	Description
OK-to-Remove		This blue LED lights when the hard drive has been taken offline and is safe to remove from the system.
Service Required		Reserved for future use.
Activity		This green LED lights when the system is powered on and a hard drive is present in the monitored drive slot. This LED flashes slowly during the hard drive hot-swap procedure. It flashes rapidly when the hard drive is spinning up or down, or during read/write activity.

Fan Tray Status LEDs (0-2)

The fan tray LEDs are located behind the front cover, directly above each fan tray. Note that these LEDs give information only for fan trays 0-2; they do not give information on fan tray 3, located inside the system.

FIGURE 1-5 Fan Tray Status LEDs

This figure shows the location of the fan tray status LEDs located along the top right section of the system, above each fan tray (fan trays 0-2).

[ D ]

The following table describes the fan tray LEDs.

TABLE 1-4 Fan Tray LEDs
Name		Description
Service Required		This amber LED lights when there is a fault detected with the fan tray. Note that the Service Required LEDs on the front and back panels also light when this occurs.
Activity		This green LED lights when the fan tray is on and operating normally.

Alarm LEDs

The alarm LEDs are located at the front of the system, along the left side of the front cover.

FIGURE 1-6 Alarm LEDs

This figure shows the location of the alarm LEDs located along the top left side of the system.

[ D ]

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 1-5. 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).

In all cases when the user sets an alarm, a message is displayed on the console. For example, when the Critical alarm is set, the following message is displayed on the console:
Note that in some instances when the Critical alarm is set, the associated alarm indicator is not lit.

SC Alert: CRITICAL ALARM is set

Locating Back Panel Components and LEDs

Back Panel Components

FIGURE 1-7 shows the system components that you can access from the back panel. Note that the power supplies shown in FIGURE 1-7 are for the DC-powered servers; the power supplies for the AC-powered servers would be in the same location as those shown in FIGURE 1-7, but would have different input connectors.

Back Panel Slots and Ports

The back panel provides access to the PCI slots, external ports, and Advanced Lights Out Manager (ALOM) card ports.

PCI Slots

The Netra 440 server has three 33-MHz PCI slots and three 66-MHz PCI slots. These are labeled on the back panel. The Advanced Lights Out Manager (ALOM) card is located to the left of the PCI slots.

FIGURE 1-9 PCI Slots

This illustration shows the six PCI slots, numbered 0 to 5, from right to left. Low-speed slots are 0, 1 and 3. High-speed slots are 2, 4 and 5.

External Ports

The Netra 440 server has eight external data ports on the back panel, which are described in TABLE 1-10.
