The Sun Fire V480 server is a rack-based server that measures 8.75 inches
high by 17.5 inches wide by 24 inches deep (22.225 centimeters [cm] x
44.7 cm x 60.96 cm), as depicted in Figure 1-1.

The server weighs approximately 79 pounds (35.83 kilograms [kg]) in its
minimum configuration and up to 97 pounds (44 kg) fully configured. The
server is mountable in either a two or four-post rack by using rack mount
kits.

Sun Fire V480 Server Dimensions

The Sun Fire V480 server includes a bay for a slim-line Digital Video Disk

The Sun Fire V480 server can be rack-mounted into a four-post or
two-post rack. The server ships with a rack-mount kit and a cable
management arm, which are required for installing the Sun Fire V480

server into a Sun four-post rack (Delorean, Sun Fire rack, or NGR-900
rack) or other EIA-310-D-1992-compliant, 19-inch wide cabinet.

Space Considerations

The Sun Fire V480 server is five Rack Units (RU) high and 24 inches deep.
The rack that you use must be able to accommodate these dimensions, as
well as the total weight of the server or servers, any other installed
components, and the rack kits. The Sun expansion cabinet is 72 inches tall
and holds a power sequencer that allows an administrator (with the aid of
a colleague due to the weight involved) to install six Sun Fire V480 servers
into the rack (seven servers would fit into a rack, but the rack could only
power six servers).

D

o

no

Caution – When you install servers into the rack, ensure that the rack is
securely bolted to the floor or has sturdy and extendable anti-tip legs
installed and extended. This prevents the cabinet from tipping when one
or more servers are fully extended out of the front of the cabinet.

The ambient temperatures of the CPU modules and the Fibre Channel
backplane are monitored by the Platform Information and Control Library
(PICL) driver of the Solaris™ Operating System (Solaris OS). This
software polls the thermal monitoring devices that are connected to the
thermal diodes and monitors the status of the fan trays.
The server’s environment is also monitored at the Boot PROM level.
These monitoring devices ensure that the devices being monitored are
operating within a prescribed temperature range. If one or more
monitored devices are above or below their prescribed temperature range,
warnings are issued to the system console and the system Fault LEDs
light appropriately.
Note – As a safeguard, a hardware trip point shuts down the server if the
CPU thermal set point is exceeded. This procedure is not a graceful
shutdown.

In addition to monitoring the temperature ranges of devices, the software
and hardware components also monitor the system fans, power supplies,

system LEDs, and the front panel system control switch.

Temperature and Humidity Levels

D

o

no

To operate properly, the Sun Fire V480 server requires a temperature
range between 41 degrees Fahrenheit (F) to 95 degrees F (5 degrees
Celsius [C] to 35 degrees C) with a relative humidity between 20 percent
and 80 percent.

1-18

In a non-operating environment, the temperature range that must be
maintained is -4 degrees F to 140 degrees F (-20 degrees C to 60 degrees C)
with a humidity reading of less than 95 percent.
The Sun Fire V480 server incorporates several features to maintain proper
temperature and cooling during operation, including environmental
monitoring software and system fans.

The fan trays in the Sun Fire V480 server are not hot-swappable or
hot-pluggable. Therefore, both fan trays must remain in the server at all
times. In addition, the fans that are located within the fan trays run at full
speed at all times and have no variable speed controls.

Airflow through the server moves from the front to the rear of the
enclosure. Two fan trays within the Sun Fire V480 server are responsible
for this airflow and for maintaining the temperature within the enclosure,
these are:
●

Fan Tray 0 – CPU fan tray

●

Fan Tray 1 – PCI fan tray

Fan Tray 0

The CPU fan tray (Fan Tray 0) contains three individual fans. Fan Tray 0 is

The PCI fan tray (Fan Tray 1) contains two fans. Fan Tray 1 is accessible

The two standard hot-swappable power supplies in the Sun Fire V480
server provide N+1 redundancy to the system. If one power supply fails,
the system continues operating with the remaining operational power
supply.
The power supplies have the following characteristics:
●

Operate over an AC input range of 100 to 240VAC, at 50 to 60 hertz
(Hz), without user intervention.

●

Capable of providing up to 1100 watts of direct current (DC) power.

●

Plug directly into connectors on the Power Distribution board.

●

Provide 48-volt (V) and 5V standby outputs to the server.

●

The 48V output powers point-of-load DC/DC converters that
provide 1.5V, 1.8V, 2.5V, 3.3V, 5V, and 12V to the components.

●

Output current is shared equally between both supplies by means of
active current-sharing circuitry.

Note – Each power supply has its own AC inlet and power cord, therefore
an ideal configuration would be to plug each power supply into separate
AC circuits. If a circuit fails in this case, the second circuit is more likely to
remain functional, providing power to the system.

D

no

Accessing the Power Supplies

The power supplies are accessible from the front of the system chassis (see
Figure 1-2 on page 1-8). However, the power supplies’ corresponding AC
outlets are located at the rear of the chassis (see Figure 1-5 on page 1-13).
The power supplies are located in bays 0 and 1, starting at the left when
viewed from the front panel.
Note – Power supply bay 0 or bay 1 should always be occupied because
their internal fans help cool the disk drives.

Figure 1-12 Power Distribution Board (Detailed View)

The Field Effect Transistor (FET) switch is designed to handle large
amounts of current and voltage. The FET switches control the 48VDC
power to the CPUs by provide overcurrent protection to the CPUs. The
third FET switch provides the same protection to the system power.

Power Distribution

Point-of-load DC/DC converters provide and regulate 1.5V, 1.8V, 2.5V,
3.3V, 5V, and 12V power applied to the different server components.

Figure 1-13 on page 1-24 shows a detailed view of the power distribution
paths in the Sun Fire V480 server.

no

Each of the power supplies provides 48V, as well as the 5V standby power
used by the system LEDs. The Power Distribution board provides the 48V
necessary to power each of the CPU/Memory modules.

The logic signals are the Power on and Power OK (POK) signals delivered
by the different system components when the system is powering up.
Each converter issues a Power on signal upon receiving power and a POK
signal after successfully powering up.

The DC/DC converters can be a single point of failure for the system.
There are LEDs associated with each of the converters that are pertinent to
system power-on. See ‘‘Sun Fire V480 Server LEDs’’ on page 1-25 for
further details.

Sun Fire V480 Server Power Supplies
Power is passed to the centerplane and then converted by the DC/DC
converters to provide:
1.5V, which provide 16 Amps for bus termination

●

3.3V, which provide 30 Amps for logic signals

●

2.5V, which provide Amps to 10/100/1000 Ethernet chips

●

1.8V, which provide Amps for the Cassini ASICs

Power then passes to the PCI Riser board and is distributed across three
DC/DC converters to provide (see Figure 1-13):
●

3.3V, which provide 30 Amps required to provide PCI support

●

5V, which convert power to be used by the centerplane and the PCI
Riser board to provide the 21 Amps required for PCI support, disk
drives, the DVD-ROM, the front panel LEDs, and system logic

●

12V, which convert power to be used by the centerplane and the PCI
Riser board to provide the 5 Amps required for PCI support, disk
drives, fans, and the -12V converter for PCI support

Sun Fire V480 Server LEDs

Sun Fire V480 Server LEDs
The Sun Fire V480 server contains several different LEDs for determining
system status and assisting in diagnostics. These LEDs are:
Front and rear panel LEDs

●

Disk drive LEDs

●

Fan tray LEDs

●

Power supply LEDs

●

Centerplane LEDs

●

PCI riser LEDs

Upon bootup, all LEDs are individually toggled on and off to ensure that
they are functioning properly. If a fault occurs, the appropriate LED
illuminates to indicate a problem.

Because all front panel, rear panel, and interior status LEDs are powered
by the server’s 5V standby power source, Fault LEDs remain illuminated
for any fault condition that results in a shutdown.
