2.3 Installation and operation precautions
Installation precautions
Follow the instructions below to ensure safety when positioning the SE server:
The Server Unit, Management Unit, Application Units and further components are installed in one or more closed
racks. Consequently the ambient operating temperature inside the rack may be higher than the room
temperature. Install the business server in an environment in which the ambient temperature is always below 35 °
C (95 °F).
Adjust air circulation to prevent the temperature inside the rack from exceeding the maximum ambient
temperature specified for the server components.
The maximum allowable operating temperature of the server components is 35°C (95 °F).
A certain amount of air flow is required for safe operation of the server components.
The server components have ventilation openings at the front and rear. Do not cover or close the ventilation
openings. Doing so may cause the server components to overheat.
Positioning the Business Server may cause the entire rack to be unstable because of uneven mechanical loading.
The racks of the SE server have no stabilizer. When an SU or heavy peripherals are pulled out of the rack, there
may therefore be a risk of it tipping over.
The power supply for the server components is implemented via power distribution units mounted in the rack
which themselves must be connected to the inhouse power supply using appropriate CEE connectors.
The large number of power supply components in the rack means that the configuration can generate leakage
currents > 3.5 mA.
For this reason the rack may be connected to the in-house power network only via permanent links or industrial
cables in accordance with IEC 60309 (formerly IEC 309) .
CAUTION!
Equipment damage
Be sure to follow the precautions below when installing or operating the equipment.
Otherwise, the SE server may be damaged.
!
WARNING!
The SE server is installed on the vendor’s premises. Modifications may only be carried out by Customer
Support. The customer may not make any changes to the server!
The following section is therefore for information purposes only.
!
CAUTION!
Equipment damage
In configurations with multiple feed cables such as the SE server, it must be noted that all cables must be
disconnected to disconnect the system from the power network.
