It is important to be aware of the information listed below before installing your Trenton rackmount
computer. System performance may be affected by incorrect usage of these features.

Incoming AC power must be supplied to the rear-mounted, fixed power supply receptacle located in the
rear of the chassis. This AC power connection ensures that the system power supply is connected to a
power source with a solid earth ground and is capable of delivering 110-240VAC at 50 to 60Hz.

Incoming AC power must be supplied to both of the receptacles located on the rear of the chassis. This
dual AC power connection ensures that the main system power supply as well as the fail-over supply are
each connected to a power source with a solid earth ground and is capable of delivering 110-240VAC at 50
to 60Hz. The typical maximum current draw of the rackmount computer is 4.07A per incoming power
receptacle.

The maximum current limits for the +5V, +3.3V and +12V outputs from the system power supply are 32A,
32A and 65A respectively. The system’s power monitoring circuits will shut the system down if these
maximum current limits are drawn from the power supply.

When installing the chassis, ensure that a minimum free air space is available around the system. The
installation should have a minimum of 4-6 inches (101-152mm) behind the chassis and 1-3 inches (25-
75mm) in front of the chassis. Any front cabinet doors or access aisles must accommodate a TRC4011 /
TVC4403 front chassis clearance of at least 4.0” (102mm) in order to provide proper cable clearances for
any front panel I/O port connections and to gain access to the system air filter for maintenance. Ideally, a
chassis clearance of 0.5-1.5 inches (13-38mm) above the system is desirable, but not required.

OUNTING
The TRC4011 / TVC4403 system can be installed in a rackmount cabinet that conforms to EIA standards
for computer equipment with 19-inch wide panels. The cabinet must be tall enough to accommodate the
computer’s height and deep enough to accomendate the system’s depth, while providing the proper
clearences for air flow and cabling. A cabinet with a standard depth of 31.5 inches (800mm) should be
sufficient; however, a rack with a non-standard depth dimension of at least 22 inches (559mm) will provide
the suggested minimum front and rear chassis clearances needed for an installation.
