10.4Interpreting the Front and Back Panel LEDs

The Sun Fire V120 and Netra 120 servers each contain two front panel LEDs:

A Power LED (see FIGURE 10-7)

This LED is lit when the server is powered on. It is unlit when the server is in standby mode.

A Fault LED (see FIGURE 10-7)

When the Fault LED is lit (but not flashing), this indicates a problem that is not fatal to the server but that you should attend to as soon as possible. Circumstances that cause the Fault LED to light up include the following:

The temperature inside the server’s enclosure is unusually high.

The voltage on one of the server’s output supply rails is unusually high.

One of the server’s internal circuit breakers has tripped, indicating a problem with a device connected to the SCSI or USB ports.

The System Configuration Card, containing the server’s serial number, MAC address and NVRAM settings, has been removed.

One of the DC power inlets has failed.

The LOM watchdog has timed out, indicating that the server has locked up. You can configure the server to restart automatically after a lockup (see Section 9.2, “Configuring Automatic Server Restart (ASR)” on page 9-8).

When the Fault LED flashes on and off, a problem has occurred that is fatal to the server. Circumstances that cause the Fault LED to flash include the following:

The speed of one of the fans inside the server is too low.

The temperature inside the server’s enclosure is too high. (By default, this causes the server to shut down. For information about configuring the server not to shut down in this condition, see Appendix C.)

The voltage on one of the server’s output supply rails is too high. (By default, this causes the server to shut down. For information about configuring the server not to shut down in this condition, see Appendix C.)

The temperature inside the CPU is too high. (This causes the server to shut down.)

V120, 120 specifications

Sun Microsystems' V120 and 120 servers emerged as robust solutions in the early 2000s, catering primarily to small to medium-sized enterprises and branch offices. These servers were built to deliver reliable performance, ease of use, and efficient resource management, making them appealing choices for organizations aiming to balance performance with budgetary constraints.

One of the standout features of the Sun V120 server was its UltraSPARC III processor architecture. This powerful processing capability provided substantial improvements in processing power and energy efficiency, allowing users to run demanding applications and serve multiple users without a hitch. The UltraSPARC III architecture supported a 64-bit computing environment, enabling better memory utilization and rapid execution of high-volume transactions.

In terms of memory, the V120 could accommodate up to 32GB of DDR SDRAM. This significant memory capacity allowed for enhanced performance in data-intensive applications, facilitating smoother multitasking and reduced response times. The server supported dynamic reconfigurability, which meant system resources could be adjusted on-the-fly without shutting down operations, thus ensuring minimal downtime.

Storage solutions on the V120 were flexible and optimized for various requirements. The server offered options for internal hard drives for local storage, as well as configurations that supported external storage systems, providing users with a variety of scalability options. The inclusion of multiple SCSI and IDE interfaces allowed for better integration with existing IT infrastructure.

Networking capabilities in the V120 included integrated Ethernet interfaces, which supported both Fast Ethernet and Gigabit Ethernet options. This ensured seamless connectivity and sufficient bandwidth for network applications, while the server’s compact design made it easy to deploy within existing setups.

As for its operating systems, the V120 was compatible with Solaris, Sun's flagship UNIX-based operating system, which was celebrated for its scalability and reliability. Organizations could also run Linux distributions, further broadening the server's appeal and making it versatile for varied workloads.

Additionally, the V120’s design prioritized energy efficiency, which helped companies reduce operating costs and their environmental footprint. The server’s compact form factor allowed for efficient cooling and reduced space requirements.

In conclusion, the Sun V120 server, alongside the V120 model, represented a marriage of advanced technology, expansive features, and flexible deployment options. It provided businesses with a dependable platform for various applications, establishing itself as a valuable tool for organizations looking to leverage the power of enterprise computing without exorbitant costs.
