2.2.3.2 Subrack installation
The ambient temperature for operation of the FOX615 with active cooling is
rated from -25°C to +60°C with a relative humidity of up to 95% (non-con-
densing).
The ambient temperature for operation of the FOX615 with passive cooling
is rated from -25°C to +55°C with a relative humidity of up to 95% (non-con-
densing).
For detailed specification of the temperature range for FOX operation and
related operational conditions, refer to
1KHW002460 FOX61x Product Fea-
tures and Characteristics .
NOTICE
Attention to temperature range! Attention to temperature range. Risk of equipment damage!
It is essential to preserve the system specifications and to prevent the sys-
tem from overheating.
→ The site of installation must provide an ambient temperature within the
specified range at any time.
If you plan to stack equipment, take into account that the system below will
heat up the air defining the ambient conditions for the equipment above!
To avoid overheating of the equipment due to inadequate installation adhere
to the following instructions.
• Do not block the air flow through the subrack and its cards.
• Avoid the installation of other equipment directly above the FAMO1 or
FAMO1-F unit. Respect a minimum distance of 2 HU (2 x 44.45 mm) to
the equipment above.
If the equipment above is sensible for dissipated heat, you must install a
heat deflection shield R7AI above the FAMO1 or FAMO1-F
(refer to the
figures in section Arrangement in the rack (on page 17)).
• Avoid the installation of the FOX615 subrack (cable tray) directly above
other equipment. Respect a minimum distance of 2 HU (2 x 44.45 mm) to
the equipment below.
If the equipment below dissipates heat, you must install a heat deflection
shield R7AI below the cable tray (refer to the figures in section
Arrange-
ment in the rack (on page 17)).
• Do not install subracks without a cable tray. The cable tray is an integral
part of the FOX615 and allows cold air to flow into the subrack. Install the
cable tray in such a way that 2HU space is provided between the tray and
the chasis air inlet.
• If you stack equipment, install heat deflection shields R7AI between the
subracks (refer to the figures in section Arrangement in the rack (on
page 17)) to evacuate the heated air to the rear or front of the rack.
• In cabinets using a swing frame the uppermost position of an R7AI is
height 1. In cabinets without a swing frame it is height 2. This allows opti-
mum air evacuation through the front door.
• In cabinets without active ventilation it is recommended to omit the dust
filters at the top.
