Power Supplies
ARX power supplies (all models/platforms):
• ARX-500 Power Supply
The ARX-500 power supply distributes up to 600 Watts of DC power to
the chassis components. The power supply runs at 72% efficiency, so it
consumes up to 833 Watts of AC power (833/0.72) to meet the 600-Watt
demand. This is equivalent to 2,843 BTUs/hour.
• ARX-1500 Power Supply
The ARX-1500 is powered by a 1+1 redundant power system consisting
of two power modules and one power system frame. Two power modules
are recommended for full redundancy and load-sharing.
Each power supply can provide the following:
– Hot-swappable/hot-pluggable, redundant power
– Load sharing between two power modules
– Separate AC line power cord for each power module
– Power Module Input: 100-240 VAC; 47-63Hz, 4 -2A
– Active Power Factor Correction (PFC)
If the power unit is operating properly, then the individual LEDs and
external warning LEDs are lit green. If you remove a power supply, then
the warning buzzer in the power system sounds, and the external warning
LED, which displays the status of the total power supply system, begins
to blink. The LEDs on the front of the power module, which indicate the
power supply’s status will not light. The power supply continues to back
up the power output without affecting the computer system’s operation.
When the warning buzzer sounds, you can reset the warning buzzer by
pressing the buzzer reset. When you re-insert the power module that was
removed earlier, then the sound of the warning buzzer disappears and the
LEDs above the power supply turn green.
• ARX-2000 Power Supply
The AC/DC power supplies provide the following functions:
– Input: 100VAC – 240VAC, 47/63HZ
– Output: -12V @ 1A, +3.3V @ 32A, +5V 30A, +12V 62A
– Remote sensing to maintain stable voltage and to account for any DC
loss in cabling.
– AC alarm to indicate when power is about to be removed from the
system. When this alarm is activated, the power supply maintains full
regulated load for a minimum of 20 milliseconds, enabling the system
to power down gracefully.
• ARX-2500 Power Supply
The ARX-2500 is powered by a 1+1 redundant power system consisting
of two power modules and one power system frame. Two power modules
are recommended for full redundancy and load-sharing.
