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 each receptacle located at the rear of the chassis. This AC power
receptacle must be connected to a power source with a solid earth ground, and 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 7-8 inches
(178-203mm) in front of the chassis. Any front cabinet doors or access aisles must accommodate a
THS2085 front chassis clearance of at least 7.0” (178mm) in order to provide proper clearance for the
chassis’ front door, 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 THS2085 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 accommodate the system’s depth, while providing the proper clearances for air
flow and cabling. A cabinet with a standard depth of 31.5 inches (800mm) will provide the suggested
minimum rear chassis clearances needed for an installation.
