Environmental Guidelines
General environmental and installation guidelines
The VIPRION
®
4800 platform is an industrial network appliance that is designed to be mounted in a standard
19-inch EIA rack. Follow these guidelines to adhere to safety precautions:
• Install the rack according to the manufacturer's instructions and check the rack for stability before placing
equipment in it.
• Build and position the rack so that once you install the platform, the power supply and the vents on both
the front and back of the unit remain unobstructed. The platform must have adequate ventilation around
the unit at all times.
• Although not required, a 1U space between units makes it easier for you to remove the unit from the
rack in the event that the unit requires service. A 1U space between units also provides additional cable
routing options.
• Use an open-style rack or cabinet to reduce the restrictions to airflow. Use of a closed cabinet is not
recommended. If a closed cabinet must be used, pay special attention to ensuring that there is adequate
airflow on the front and rear of the chassis, as well as in and out of the cabinet.
• The installation should be set up in a hot aisle-cold aisle configuration. Be sure to minimize leakage
between the two sides.
• Block off empty rack spaces to prevent back-to-front leakage of air flow. Recirculation of hot discharge
air to the chassis air inlet will greatly impede the system cooling efficiency.
• Ensure that your cabinet and data center arrangement has adequate air flow to minimize back pressure
on the discharge side of the system. Restricting flow causes the chassis to run hotter than it needs to.
• Use good cable dressing practices to help minimize detrimental effects on chassis cooling by reducing
the amount of restriction to the chassis inlet. The VIPRION 4800 platform comes provided with cable
managers. Avoid having cables hang in front of the chassis air inlet.
• Do not allow the air temperature in the room to exceed 104°F (40°C).
Note: NEBS-certified platforms can withstand air temperatures up to 131°F (55°C). The maximum
temperature is only required to be met for a short period of time.
• Do not plug the unit into a branch circuit shared by more electronic equipment than the circuit is designed
to manage safely at one time.
Important: This product is sensitive to electrostatic discharge (ESD). F5
®
recommends that you use proper
ESD grounding procedures and equipment when you install or maintain the unit.
Caution: Customers should not attempt to replace batteries. There is a risk of explosion if a battery is
replaced with an incorrect type. Field technicians should dispose of used batteries according to the
instructions.
Attention: Il y a risque d'explosion si la batterie est remplacée par une batterie de type incorrect. Mettre
au rebut les batteries usagées conformément aux instructions.
