Measuring points of the working temperature and humidity of S12800 in the equipment
room mean the values measured from the floor above 1.5 m and 0.4 m from the front of
the rack when there are no protection boards.
The short-term work condition means that the work cannot exceed consecutive 48h or
accumulated 15 days in a year.
If the humidity in the equipment room is too high for long time, it causes the poor insulation
and even electricity leak of insulation materials easily. Sometimes, the mechanical
performances of materials change and the metal parts are corroded easily, too.
If the relative humidity in the equipment room is too low, insulation pads shrink, which causes
the fastened screws loose. Meanwhile, in dry environment, static electricity appears easily,
which harms the circuits on the switch.

According to the actual weight of the installed switch and its accessories, estimate the ground
load-bearing requirement and ensure that the ground load-bearing capability of the installation
place meets the requirement. For the weights of the switch components, refer to
Entire Device and Common Module Specifications
When estimating the ground load-bearing, consider the capacity expanding of the switch in the
future (for example, add a card).

To ensure that there is enough operation space for moving the chassis and plugging the
module, it is recommended that the aisle width of the equipment room is no less than 0.8m. If
installing the switch in the cabinet, the net height of the equipment room cannot be less than
3m.
To be convenient for cooling and maintaining the switch, do not install the switch against the
wall. The front and rear space of the switch should be no less than 0.7m.

Dust is harmful for the switch operation. Dust causes electrostatic absorption, which makes the
poor contact of metal connectors. Electrostatic absorption appears especially when the
temperature and humidity are lower, which affects the device life and easily causes
communication fault. The requirement for the dust content and particle diameter in the
equipment room is as shown in appendix table D-3:
