The following sections briefly introduce the hardware on the rear of the enclosure.
CPU/Control Board
The CPU/Control board (FIG. 3) is on the left rear of the enclosure, between the input connectors and the
power supplies.
Each CPU includes the following port options:
Control port (DB-9 serial) – for attaching an external control device (see page 31)
USB (mini-B) port
–
for attaching an external control device (see page 33)
Enc Link port (Ethernet RJ-45)
–
for linking to other types of enclosures (see page 23)
Two LED indicators are located on the far left side of the CPU/Control board:
Communication Status Indicator

Power Supply Units
Each power supply unit on the rear of the enclosure (FIG. 4) has a power receptacle that will accept
all major international standard power sources. (US power cords are included with all shipments unless
ordered otherwise.) Maximum power specifications are provided on the power supply receptacles.
For information on applying power, see page 38.
The power supply unit has three LED indicators (listed left to right):
AC ( ): When the LED is green, the power is good.
DC ( ): When the LED is green, the power is good.
Temperature ( ): When the LED is not illuminated, the temperature is good; when the LED
is amber, the temperature is above normal.
Caution: Each power supply has a small toggle switch to the left of its LEDs that controls internal
power and must remain flipped to the right for the system to operate. Do not flip this switch to the left.
