This chapter describes the Sun Fire V125 server and contains an overview of the following main features:
Bezel Features
The front bezel of the Sun Fire V125 server contains the server status indicators and a space for placing an identification label.
FIGURE 1-1 Location of Status Indicators
Server Status Indicators

Front Panel
Access the front panel by opening the bezel, which you do by pressing the release buttons on each side and rotating the bezel forward.
The front panel contains the following:
- On/Standby button
- Hard drive
- System configuration card
On/Standby Button
The On/Standby button controls only the power state of the server; it does not isolate the server from its electrical power source. The On/Standby button is a momentary switch that you can operate two ways:
- Press and immediately release
- Press and hold down for more than 4 seconds
The results of these actions are summarized in TABLE 1-2.

Table describes power states of the server when running Solaris OS, not running Solaris OS, or in standby.Controlling Server Power States
The server immediately goes into Standby mode as soon as it is connected to a power source. As long as it remains connected to the power source, the server stays in either the Standby or On power state. An explanation of the power states is given in TABLE 1-3.
TABLE 1-3 Explanation of Power States
Power State
|
Description
|
On
|
Server is connected to a power source and the power is enabled.
|
Standby
|
Server is connected to a power source but power is not enabled.
|
Off
|
Server is not connected to a power source. Power cable is disconnected.
|
Table describes on, standby, and off power-states for the server.
Note - The only way to completely remove power from the server is to disconnect the power cable.
|
Hard Drive
The Sun Fire V125 server ships with one hard drive; however, the server has slots for two hard drives. The slots accept any Sun LVD SCSI hard drive conforming to the 1-inch SCA-2 form factor.
The hard drive has two indicators associated with it. See TABLE 1-4 for a summary of what the indicators mean.

For information on removing and replacing a hard drive, see Removing and Replacing the Hard Drive.
DVD Drive
The Sun Fire V125 server contains a bay to accept an optional slimline ATAPI DVD drive. The bay is located on the front panel and is accessed by opening the bezel.
For information on DVD drive installation, see Removing and Replacing the DVD Drive.
System Configuration Card
The system configuration card (SCC) is housed in a slot behind the front bezel, next to the On/Standby button. The card contains unique network identity information, including the MAC address and host ID (known as the IDPROM), and the OpenBoot PROM configuration (also known as NVRAM).
The server attempts to access the SCC while booting.
- If a properly formatted card is not present in the reader, the system does not boot.
- If the content of the NVRAM section is invalid, the system is not initialized with its default NVRAM configuration.
It is essential that you store the SCC safely if you have to remove it from the server, and replace it before restarting the system.
For more information, see Swapping a System Configuration Card Between Servers.

The I/O ports on the back of the Sun Fire V125 server are arranged as shown in FIGURE 1-2. For more information on the I/O ports, refer to the Sun Fire V125 Server Getting Started Guide.
Network Status Indicators
Each network connector has two status indicators.
FIGURE 1-3 Location of Network Status Indicators
The network status indicators convey:
- Network link status
- Network speed status (does not apply to the NET MGT port)
For a summary of what the Network Link status indicators mean, see TABLE 1-6.

|
Table describes the network speed status when the green Network Speed indicator is on or off.USB Ports
The server has two USB ports for attaching supported USB devices. The ports are USB 1.1 compliant. They support device speeds of 1.5 Mbit/sec and 12 Mbit/sec, and a 5V supply is available at each connector to power the external device.
External SCSI Port
The SCSI port is a multimode Ultra160 SCSI interface. To operate at Ultra160 SCSI speeds, it must be in Low Voltage Differential (LVD) mode. If a single-ended device is connected to the server, it automatically switches to single-ended mode.
Power Supply Unit
The Sun Fire V125 server has one PSU and two associated status indicators. TABLE 1-8 summarizes the function of the indicators.

System Prompts
The following default server prompts are used by the Sun Fire V125 server:
- ok - OpenBoot PROM prompt
- sc - Advanced Lights Out Manager (ALOM) prompt
- # - Solaris OS superuser (Bourne and Korn shell)
FIGURE 1-4 shows the relationship between the three prompts and how to change from one prompt to another.
FIGURE 1-4 System Prompt Flow Diagram
