Preparing for installation
Preparing the installation site
Before installing the router, inspect and prepare the installation site to be sure that the router will
work in a good operating environment. For the operating environment requirements of the router, see
Generic Operating Environment Requirements of H3C Devices Installed Indoors .
Weight support
Make sure the floor or ground at the installation site can support the combined weight of the router
and the rack. The total weight of the router includes the chassis and its components (for example,
modules and power supplies) and accessories. For information about the weights of the router and
its components, see
H3C CR16000-M Routers Hardware Information and Specifications .
TIP:
To assess the load-bearing requirements for the floor, take potential system expansion (for
example, adding more modules) also in consideration.
Temperature and humidity
CAUTION:
If condensation occurs on the chassis after you move it from a lower temperature to a higher
temperature, dry the chassis before powering it on to avoid short circuits.
Adverse temperature and humidity conditions in the equipment room will accelerate the aging of
devices and reduce the capability of the device to withstand harsh environment conditions.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and bring issues including
loose screws and circuit failure.
•
High temperature can accelerate aging of insulation materials and significantly lower the
reliability and lifespan of the router.
•
Lasting high temperature and relative humidity can aggravate corrosion of corrosive gas and
particles to the bare parts of the device and significantly reduce the service life of the device.
To prevent the preceding issues, maintain the temperature and humidity in the equipment room in
the ranges as described in
Table2-1 .
