Preparation For Installation

To ensure normal operation and prolonged
life of the DES-7200, the appropriate temper-
ature and humidity must be maintained in the
equipment room.
If the equipment room has temperature and
humidity that do not meet the requirements, the
equipment may sustain damage.

Table 1. Temperature and Humidity Requirements
Note:
1. The ambient temperature and
humidity should be measured
at the point that is 1.5m above
the floor and 0.4m before the
equipment when there is no
protective plate in front or back of
the equipment rack.
2. The short-term working condi-
tions apply where the continuous
working period does not exceed
48 hours and the cumulative total
period within a year does not
exceed 15 days.
Static Discharge Damage Prevention
To prevent damage from static electricity,
please conform to the following guidelines:
1. Be sure to a adequately ground all
electronic equipment.
2. Use appropriate dust prevention measures.
3. Maintain the required humidity in the
operating environment.
4. Always wear an anti-static wrist strap when
working around any electronic circuitry.
5. Hold a circuit board by its edges. Do not
touch any components on the PCB.
6. Do not allow clothing to touch a circuit
board. An antistatic wrist strap can only
prevent static electricity from the human
body, but cannot mitigate static electricity
from clothing.

Moving the Device
The DES-7200 is large and heavy. When
handling, please pay close attention to the
following guidelines:
- Avoid moving the equipment frequently.
- At least two people are needed to move
the equipment. Do not attempt to move the
equipment alone.
- Turn off all power supplies and unplug all
power cables before moving the equipment.
- Use the side handles to remove all line cards,
the fan tray, and the power module from the
chassis before moving.

WARNING:
Do not move the equipment by
grasping the panel, power supply
handle, or ventilation holes, as they
are not designed to bear weight.
System Grounding Requirements
Proper grounding will help to ensure stable and
reliable operation of the DES-7200. Be sure
to verify that the grounding conditions at the
installation meet the grounding requirements,
and ground all devices appropriately.
