General environmental and installation guidelines

The EM 4000 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.
  • Leaving at least 100 mm of space from the front panel of the unit to the rack front or rack door provides enough room for you to route the cables without excessive bending or insulation damage.
  • Do not allow the air temperature in the room to exceed 104°F (40°C).
  • 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 Networks 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.

Guidelines for DC-powered equipment

A DC-powered installation must meet the following requirements:

  • Use a 25 amp external branch circuit protection device to install the unit.
  • For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
  • Use only copper conductors.
  • Ground the cabling for the system on both sides.
  • Use one power feed for each individual power supply.

The platform employs a negative pressure fan system, which draws cold air in from the front of the chassis and exhausts hot air out the back of the chassis.
