The Netra T1 server’s system board contains several jumpers.

We do not recommend you change the jumper settings. However, for reference, the factory-default settings are listed in TABLE D-1,and the locations of the jumpers are shown in FIGURE D-1(which also illustrates the default settings).

TABLE D-1Factory-Default Jumper Settings

Jumper

Default Setting

Description

 

 

 

JP8

1-2 (Open)

This is the factory default setting for replacement system

 

3-4 (Fitted)

boards. It identifies the system to OpenBoot PROM and Solaris

 

 

as a Sun Fire V120 server. If you are installing a new system

 

 

board for a Sun Fire V120, make sure that the jumpers match

 

 

this setting.

 

 

 

 

1-2 (Fitted)

This setting identifies the system to OpenBoot PROM and

 

3-4 (Open)

Solaris as a Netra 120 server. If you are installing a new system

 

 

board into a Netra 120, you must set the jumpers on the

 

 

replacement board to match this setting. (Note that the factory

 

 

default setting is for the Sun Fire V120, not for the Netra 120

 

 

system. This is why you must change the setting before

 

 

installing the new board.)

 

 

 

JP7

1-2 (Open)

This jumper setting tells the system that its main processor is a

 

3-4 (Open)

550 MHz CPU. Do not alter this setting. It is correct for the CPU

 

5-6 (Fitted)

on your system board.

 

 

 

 

1-2 (Open)

This jumper setting tells the system that its main processor is a

 

3-4 (Fitted)

650 MHz CPU. Do not alter this setting. It is correct for the CPU

 

5-6 (Open)

on your system board.

 

 

 

JP9

1-2 (Fitted)

This jumper is for use by Sun engineers in the development of

 

 

OBP software. Do not alter its setting.

 

 

 

JP13

1-2 (Open)

This jumper is for use by Sun service engineers. It resets the

 

 

LOM device. Do not alter this setting.

 

 

 

JP14

1-2 (Open)

This jumper is for use by Sun service engineers in the event that

 

 

the LOM device on the system board is broken. The default

 

 

setting is Open. If you alter this setting to Fitted, then, if the

 

 

LOM is broken, you can use the On/Standby rocker switch to

 

 

power the system on (or down to standby mode). Note that the

 

 

power signals from the On/Standby switch pass through the

 

 

LOM device, and that setting this jumper to Fitted causes the

 

 

signals from the rocker switch to bypass the LOM.

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.
