Chapter 4 Installation and Maintenance Information About Preparing to Install the SCE 2000 Platform 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 • Site Requirements Airflow Figure 4-2 Left Airflow Through the SCE 2000 MNG 1 MNG 2 ALCITNIKV/E101/010000/ ALCITNIKV/E101/010000/ CONSOLE AUX PWR A PWR B STATUS BYPASS LINK RX TX LINK RX TX RX MM TX RX MM TX GBE-1 SUB LINE NET Cisco S4CxEG2B0E00 Series LINK RX TX LINK RX TX RX MM TX RX MM TX GBE-2 SUB LINE/CASCADE NET Right 92775 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 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

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.

Figure 4-2
Airflow Through the SCE 2000
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.
