ITTING THE COMMUNICATION SERVER
CHAPTER 4 INSTALLATION
Safety regulations
Be sure to observe the following safety regulations before carrying out work inside a communication
server:
CAUTION: Components, interface cards or system modules can be damaged by electrical voltage.
Always shut down, then disconnect the communication server from the power supply and then wait 3
minutes before removing the housing cover.
CAUTION: Components can be damaged by electrostatic discharge when touched. Always touch the
earthed metal case of the communication server before carrying out work inside the housing. This also
applies to interface cards and system modules that are no longer packed inside the ESD pro-tective wrap-
ping.
Wall mounting
There are two possibilities for wall mounting. In the first variant the front panel faces right (see Minimum
distances for wall mounting (front panel facing to the right)); in the second, it faces downwards (see
Minimum distances for wall mounting (front panel facing downwards)
). The wall-mounting option chosen
will depend on the way the cables are routed. The LED display remains visible whatever the mounting
position, even when the cable cover is fitted.
CAUTION: A wall-mounting option in which the front panel faces upwards or to the right is not permitted.
Inadequate heat dissipation can damage the communication server.
Minimum distances
To ensure adequate heat dissipation, minimum distances need to be maintained with other objects such
as cable ducts, cabinets or mobile objects. Maintaining minimum distances also allows the installation of
EMC • Do not position in strong electromagnetic fields of
radiation(e.g.near x-ray equipment, welding equip-
ment or similar).
Heat dissipation • Do not place any objects on top of the communica-
tion server.
• Observe the clearance requirements for wall
mounting and desktop installation (see Minimum
distances for wall mounting (front panel facing to
the right) and Minimum distances for wall mounting
(front panel facing downwards)).
• In a rack-mounted installation the space to the left
and right between the communication server and
the wall of the 19” rack must remain empty.
Environment • Ambient temperature 5 °C...45 °C
• Relative humidity 30…80%, non-condensing
