General environmental guidelines
The VIPRION® 4400 Series 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.
- Do not allow the air temperature in the room to exceed 104°F
(40°C).
Note: NEBS-certified units 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.
Guidelines for the AC-powered platform
An AC-powered installation must meet these requirements:
- Install the unit using a 20 amp external branch circuit protection device.
- Normally, one power feed is used for each individual power supply.
Important: The platform must be installed in
a RESTRICTED ACCESS LOCATION, such as a central office or customer premises
environment.
Note: The power cables included with this unit are
for exclusive use with this unit and should not be used with other electrical
appliances.
Note: These guidelines apply to
STATIONARY PLUGGABLE EQUIPMENT TYPE A with simultaneous multiple connections
to the AC MAINS SUPPLY:
- The building installation shall provide a means for connection to protective earth; and
- The equipment is to be connected to that means; and
- A SERVICE PERSON shall check whether or not the socket-outlet from which the equipment is to be powered provides a connection to the building protective earth. If not, the SERVICE PERSON shall arrange for the installation of a PROTECTIVE EARTHING CONDUCTOR from the separate protective earthing terminal to the protective earth wire in the building.
Note: High leakage current. Earth connection
essential before connecting supply.
Guidelines for the DC-powered platform
A VIPRION® DC-powered installation must meet these requirements:
- Install the unit using a 25 amp external branch circuit protection device.
- One power feed must be used for each individual power supply.
- For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
- Use only copper conductors.
- The DC MAINS powering the equipment shall be connected to protective earth.
Important: The platform must be installed in
a RESTRICTED ACCESS LOCATION, such as a central office or customer premises
environment.
Note: The power supply for the VIPRION® DC
platform does not have an on/off switch. You control the power from the
DC power source.
Note: You must use copper wire for the ground wire and all lead
wires.
Note: You should coat bare conductors with an appropriate
antioxidant compound before you make crimp connections. You should bring
all unplated connectors, braided strap, and bus bars to a bright finish,
and then coat them with an antioxidant before you connect them.
NEBS platform guidelines
This information applies to the Network Equipment-Building System (NEBS) version of the VIPRION 4400 Series platform.
This equipment meets NEBS requirements per GR-63-CORE.
This equipment is suitable for installation in these locations:
- Network Telecommunication Facilities
- Locations where the National Electrical Code (NEC) applies
Important: The intra-building interfaces of this platform,
including Ethernet, are suitable for connection to intra-building, or
unexposed wiring or cabling only with shielded and grounded cables at both
ends. The intra-building ports of the equipment must not be metallically
connected to interfaces that connect to the outside plant (OSP) or its
wiring.
Note: You should coat bare conductors with an appropriate
antioxidant compound before you make crimp connections. You should bring
all unplated connectors, braided strap, and bus bars to a bright finish
and then coat them with an antioxidant before you connect them.
Platform airflow diagram
When you install the platform into a rack, it is important to understand the unit’s airflow direction so that you can ensure proper cooling.
The platform employs a negative pressure fan system, which draws cold air in from the front and right sides of the chassis and exhausts hot air out the back and left sides of the chassis.
