System Configuration Card
System administrators often need to replace or upgrade a server with minimal downtime. To facilitate faster
upgrades and repairs, the System Configuration Card (SCC) stores the Netra 240 server’s system configuration,
including the host ID, MAC address, and NVRAM settings.
With the SCC, administrators can easily replace a Netra 240 server with minimal reconfiguration by transfer-
ring the identity from one system to another. Administrators can simply remove the SCC from one server and
insert it into another, along with the boot disk from the original system.
Diagnostics
Designed for easy diagnosis and problem repair, the Netra 240 server includes several PROM-resident and UNIX
platform-based diagnostic programs that service personnel can use.
Power-On Self-Test
Under user control, a power-on self-test (POST) can automatically execute to test the system board, NVRAM, on-
board I/O devices, and memory system each time power is applied to the system. While not intended to be a
comprehensive diagnostic, POST can quickly establish that no severe problems exist with the system.
Administrators can monitor POST tests via a serial port connection to a terminal server, another desktop system,
or an ASCII terminal.
SunVTS™ Software
Used to determine if the system is functioning properly, the SunVTS system exerciser is a graphically-oriented
UNIX application that permits the continuous exercising of system resources and internal and external peripheral
equipment. SunVTS software incorporates a multifunctional stress test of the system through operating system
calls and allows the addition of new tests as they become available.
Rackmount Enclosure and Power
The Netra 240 server is designed to provide reliable and scalable performance while reducing operating expenses
through lower real estate costs. The small form factor of the Netra 240 server enables multiple systems to be
densely packed into rackmounted systems. All internal components and field-replaceable units (FRUs)—including
UltraSPARC IIIi CPUs—are easily accessible from the top of the enclosure. A hinged front bezel allows administra-
tors to easily insert or remove components such as the hot-pluggable disk drives and the System Configuration
Card from the front of the system.
Each Netra 240 server ships with a Sun 4 post 19-in. rackmount kit. In addition, the following options are also
available:
• Rackmount kit for 19-in. 2 post
• Rackmount kit for 23-in. 2 post
• Slide mount kit for 19-in. 4 post
Each of the two slide assemblies has a detachable inner glide which allows the server to telescope in and out of
the rack and to enable toolless removal from the rack.
