▶ If a DC power cord is used, the server must be connected to a proper DC
source and earth ground stud/end.
▶ Ensure that the server is connected to a properly grounded power outlet
close to the server.
▶ Ensure that the power sockets on the server and the properly grounded
power outlets are easily accessible.
▶ The On/Off button or the main power switch (if present) does not isolate the
server from the mains power supply. In case of repair or servicing
disconnect the server completely from the mains power supply, unplug all
power plugs from the properly grounded power outlets.
▶ Always connect the server and the attached peripheral devices to the same
power circuit. Otherwise you run the risk of losing data if, for example, the
server is still running but a peripheral device (e.g. memory subsystem) fails
during a power outage.
▶ The adequately shielded data cables must be used.
All data and signal cables must have sufficient shielding. The use of cable
type S/FTP Cat5 or higher is recommended. Use of unshielded or badly
shielded cables may lead to increased emission of interference and/or
reduced fault-tolerance of the device.
▶ Ethernet cabling has to comply with EN 50173 and EN 50174-1/2 standards
or ISO/IEC 11801 standard respectively. The minimum requirement is a
Category 5 shielded cable for 10/100 Ethernet, or a Category 5e cable for
Gigabit Ethernet.
▶ Route the cables in such a way that they do not create a potential hazard
(ensure that no-one can trip over them) and that they cannot be damaged.
When connecting the server, see the relevant instructions in this manual.
▶ Never connect or disconnect data transmission lines during a storm (risk of
lightning hazard).
▶ Ensure that no objects (e.g. jewelry, paperclips etc.) or liquids can get inside
the server (risk of electric shock, short circuit).
▶ In emergencies (e.g. damaged casing, controls or cables, penetration of
liquids or foreign bodies), contact the server administrator or your customer
service team. Only disconnect the server from the mains power supply if
there is no risk of harming yourself.
