General environmental and
installation guidelines
The
i15000 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 after 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).GR-63-CORE NEBS-compliant shelf units can operate at maximum air temperature of up to 131°F (55°C). Operation at the maximum temperature is supported on a short term basis, per GR-63-CORE.
- 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.
- Route and secure power cords so that they do not obstruct removal of the fan tray.
Due to the weight of the platform, at least two people
are required to install this chassis into a rack. Failing to use two people
can result in severe personal injury or equipment damage.
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.
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.
Il y à risque d'explosion si la batterie
est remplacée par une batterie de type incorrect. Mettre au rebut les
batteries usagées conformément aux instructions.
Chassis rack-mount spatial
requirements
The
i15000 Series
platforms ship with a rack mount kit to
help install the system more easily. This kit requires that the rack or cabinet
has certain clearances and spacing, as shown here.Rack mounting

Guidelines for power supply units (PSUs)
All iSeries platforms support either single or dual
power supply units (PSUs). When your system includes dual PSUs, both
supplies must be of the same type. To verify this, make sure that the
supplies have matching base part numbers (PWR-XXXX). You can find the base
part number printed on the label on top of the individual power
supply.
The full part number is a nine digit
number (PWR-XXXX-YY). The base part number is seven digits and must match,
but the suffix (-YY) does not need to match.
Example of label to check PWR-XXXX part
number
If you cannot read the base part number, ensure that the
pull handles are both in a
vertical
orientation and that the sheet metal on the power cord
face for each supply has the same perforation shapes.When you add or replace a PSU in your system, be sure to
verify the supply's features and that the PWR-XXXX part numbers match to
ensure that you have the correct supply.
Guidelines for AC-powered
equipment
An AC-powered installation must meet these requirements:
- Use a50amp external branch circuit protection device to install the unit.
- Use one power feed for each individual power supply.
The platform must be installed in a RESTRICTED ACCESS
LOCATION, such as a central office or customer premises environment.
The power cables included with this unit are for
exclusive use with this unit and should not be used with other electrical
appliances.
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.
High leakage current. Earth connection essential before
connecting supply.
Guidelines for DC-powered equipment
A DC-powered installation must meet these
requirements:
- Use a 15 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.
- Cabling for the system must be grounded on both sides.
- Use one power feed for each individual power supply.
Install DC-powered equipment only in restricted access
areas, such as dedicated equipment rooms, equipment closets, or similar
locations.

uniquement dans des zones à accès reglementé, telles que des salles de
matériel, des armoires de materiel ou tout emplacement similaire.
Guidelines for NEBS platforms
This information applies to the Network Equipment-Building System (NEBS)
version of the this 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
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 connected
metallically to interfaces that connect to the outside plant (OSP) or its
wiring.
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 of the chassis.
