3.1 Unpacking and equipment check
3.1.1 Before you start …
Before you start the installation of the FOX615, please check and complete
preparatory steps as follows:
• Layout of the equipment in the rack
The proper layout of the FOX615 (and other) equipment in the rack is a
prerequisite for all installation. This layout must consider
− FOX subracks with cable trays
− Fan units (optional)
− Alarm units (optional)
− Heat deflection shields (optional)
− Power supply, including power cabling and fusing
− Signal cabling
− Other equipment
The layout must indicate the exact position of each cable tray, subrack,
fan unit, alarm unit and heat deflection devices in the rack considering its
mechanical dimensions and the rules for the equipment installation.
• Rack (19-inch / ETSI)
− Rack is installed.
− Metallic parts of the rack connected to the system ground.
• -48/-60 V
DC
power supply
− Power distribution points installed.
− Positive rail connected to system ground.
− Negative supply rail features an individual circuit breaker protection for
each subrack power feeding cable: Rating 30 A (slow).
− The power supply circuit(s) is (are) available on the FOX cable tray.
The circuit(s) is (are) checked and fused (30 A slow) at the supply side
(terminal block “A”). Refer to Figure 1: FOX615 power distribution (on
page 14).
• Heat dissipation
− Measures for heat management in the rack implemented.
This includes in particular measures for the heat evacuation from the
rack.
− The ambient temperature at the bottom of the subrack must never
exceed the temperature range for system operation as specified in
1KHW002460 FOX61x Product Features and Characteristics.
• Checks of material
− FOX equipment (cable trays, subracks, fan units, units etc.)
− Optional equipment (fan units, alarm units, heat deflection shield etc.)
− Cables (including latching clips for connectors)
Material checked and ready for installation.
• Subrack
− The slot (number) in the subrack defined for each unit.
