5 Installing the system
5.1 Assembly requirements
ξ
The server should not be installed:
in rooms with strong sunlight,
in rooms with high humidity,
in rooms with a high dust concentration,
too close to devices which generate strong electromagnetic fields,
in rooms where the device may be exposed to chemical substances.
ξ
It is recommended to mount the 2U server in a factory 19" casing or any other casing owned
by the user on condition that it meets requirements for fire-safety casings according to PN-EN
60950 "Safety of IT ports". If the server is installed in the user's cabinet, make sure there is
enough room for each server component system. This concerns both the server shelves and
cables as well as the power supply system with the battery supply support.
ξ
The servers should be supplied from a 230 V, 50 Hz AC power network.
NOTE!
A 230 V power network socket used for the server should have a protective screw and the efficiency of
its anti-shock protection should be confirmed by an appropriate protocol. Non-compliance with this
requirement causes a risk of electric shock!
Access shall be provided to the main grounding bar (terminal) in the installation area so that it
is possible to ground/earth the server (by connecting a cable with a cross-section conforming
to an appropriate standard, to the protective grounding terminal marked ).
NOTE!
ALWAYS ground/earth the server (regardless of the fact whether it is mounted in a factory casing or
the user's cabinet) with regard to its impact on the efficiency of protection against over voltage from
telecommunication lines connected to the server. Due to that, remember to tighten sufficiently the
mounting screws of the front panels of port cards to the shelf housing.
5.2 Buffer power input
A battery connection consists in making a connection between the BATTERY socket in the master
power supply and the socket on the battery casing (connecting cable is supplied with the casing).
Making compensating connections is optional and depends on the type of cabinet in which the system
is mounted. If the rack manufacturer specifies that the buses to which shelves with ports are screwed
ensure an electrical connection between individual shelves and the external casing or frame, it is not
necessary to make such connections. Otherwise, compensating connections must be added (cross
section of the cable should be selected according to an effective standard) between individual shelves
and the rack protective terminal and marked (the same symbol is used for marking locations on
the server shelf casings where the compensating cable should be connected).
6 System Telephones and consoles
6.1 Connecting additional consoles to CTS-202/CTS-203.IP
system phones
Slican CTS-202 or Slican CTS-203.IP system phones can be connected to the server. Four of these
phones can be connected to up to five Slican CTS-232 consoles. This enables the extension of the
number of quick dial keys in such a set to 162 keys. The remaining CTS-202 system phones may be
