Information About Site Requirement Guidelines

The environmental monitoring functionality in the v protects the system and components from potential
damage from over-voltage and over-temperature conditions. To ensure normal operation and to avoid
unnecessary maintenance, plan your site configuration and prepare your site before installation. After
installation, make sure the site maintains an ambient temperature of 41°F to 104°F (5°C to 40°C) with
short term temperatures ranging from 23°F to 131°F (–5°C to 55°C), and keep the area around the SCE
2000 chassis free from dust.
Planning a proper location for the SCE 2000 and the layout of your equipment rack or wiring closet is
essential for successful system operation. Equipment placed too close together or inadequately
ventilated can cause system over-heating. In addition, chassis panels made inaccessible by poor
equipment placement can make system maintenance difficult.

Airflow

Figure 4-2
Left
When you plan the location and layout of your equipment rack or wiring closet you need to consider how
air flows though your system. The SCE 2000 draws cooling air in through the intake vents on the left
side of the chassis, moves the air across the internal components, and out through the right side and rear
panel of the chassis. The above figure illustrates the airflow through the SCE 2000 .
Note Remember to leave a two inch (5 cm) clearance on both sides of the SCE 2000 and five inches (12.7 cm)
at the rear for adequate airflow for the inlet and exhaust vents.
