Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Keep the ventilation slits free to ensure good air circulation.
Make sure there is at least 3.94 in (10 cm) of space in front of the
ventilation slits of the casing.
Do not touch the housing during operation or shortly after switching off
the device. Hot surfaces can cause injury.
Exclusively mount the device horizontally in a switch cabinet.
See “Installing and grounding the device” on page 52.
Operating the device in the maximum surrounding air temperature and
stacking devices: When installing the device, make sure there is at
least 1 free rack space (approx. 5 cm) above the device, because heat
is discharged via the housing of the device.
If you are operating the device in a 19" switch cabinet: install sliding/
mounting rails for supporting the weight of the device.
Exclusively use the device with a fan module.
Fans are subject to natural wear. If one or more fans in the fan module
fail, function and lifetime of a device can be negatively affected or the
device may fail completely. Use the monitoring functions of the device
for individual fans and temperature. Depending on your installation
conditions, it may be possible to continue operating your device after
one fan has failed.
Check the temperature measured by your device: In the Command
Line Interface, use the command: show temperature; in the Graphical
User Interface (GUI) in the Basic settings dialog: System,
Temperature. The displayed temperature must not exceed the
maximum value.
See “Climatic conditions during operation” on page 72.
The device may overheat if the fan module fails or is removed. Switch
off the device or replace the fan module within 2 minutes, otherwise
failures or damage to the device may occur.
After removing the fan module during active operation, the individual
fans continue to spin for a few seconds. Do not touch rotating fan
blades. Do not insert objects into rotating fan blades.
Shielded ground
The shielded ground wire of the twisted pairs cables is connected to the
front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shield braiding.
