2 Safety instructions
To ensure reliable and safe long-term operation of your device, please note the following guidelines:
Read this user manual carefully.
Only use the device according to this user manual. Failure to follow the instructions described can
damage the device or endanger the security of your data.
Take any required ESD precautions.
WARNING
Risk of electric shock due to freely accessible power connections when the chassis is open
Risk of bruising, abrasion or shearing of fingertips due to rotating fan when the chassis is open
If the chassis is opened while power is supplied to the device, electric shock may occur if the internal
wiring is touched. If a running fan is touched while the case is open, bruises, abrasions or shearing of
fingertips may occur.
There are no necessary maintenance procedures that require opening the chassis.
Do NOT remove the cover of the chassis.
Do NOT install the device in environments where children are likely to be present.
CAUTION
Risk of burns due to tremendously heated chassis surface after a long period of operation
When the chassis is fully equipped, the surface of the chassis can become very warm after a long period
of operation. If the chassis surface is touched after a long period of operation, this can cause skin burns.
Protective gloves must be worn to transport a fully equipped chassis after a long period of operation.
Ensure that there is sufficient distance from the operator, e.g., for mounting under a table.
Do NOT install the device in environments where children are likely to be present.
Installation Location
While operating the device and the power supply units can get warm. Damage to the device can occur in a
damp environment.
Use the device only in dry, indoor environments.
Use the device only in a room with adequate ventilation.
For rack-mount installations, at least 0.5 RU (rack unit) is required above the device for ventilation.
Do not place the power supply units directly on top of the device.
Existing ventilation openings on the device must always be free.
If installing the device under the table, place the device at a sufficient distance from the operator.
Place all power sockets including the sockets for the supplied external power supply units easily
accessible and directly next to each other.

Chassis 474-BODY Safety instructions

Connection
Check the device and the power supply units for visible damage before connecting it.
Only connect the device if the device and the ports are not damaged.
Only use power supply units originally supplied with the product or manufacturer-approved
replacements.
Only use power supply units without any visible damage at the chassis or the cable.
Connect all power supply units to grounded outlets.
Ensure that the ground connection is maintained from the outlet socket through to the power supply
unit's AC power input.
Only connect the device to KVM devices using the interconnecting cable - not to other devices,
particularly not to telecommunications or network devices.
Disconnect the Device from the Circuit
NOTICE
The cable plugs on the device side can contain a lock. In the event of a necessary quick and complete
disconnection from external electric circuits:
Remove all corresponding cable plugs from the socket,
Or set the power switch of the power outlets (if available) to the “Off” position.

3 Consignes de Sécurité
Pour garantir un fonctionnement fiable et sûr de votre périphérique à long terme, veuillez respecter les
directives suivantes :
Lisez attentivement ce manuel d'utilisation.
N'utilisez le périphérique que conformément à ce manuel d'utilisation. Le non-respect des instructions
décrites peut endommager le périphérique ou mettre en danger la sécurité de vos données
Prenez toutes les précautions nécessaires contre les décharges électrostatiques.
AVERTISSEMENT
Risque de choc électrique dues de l'accès libre aux connexions électriques lorsque le châssis est
ouvert
Risque de contusion, d'abrasion ou de cisaillement des bouts des doigts dues de la rotation du
ventilateur lorsque le châssis est ouvert
Si le châssis est ouvert alors que le périphérique est sous tension, un choc électrique peut se produire si
le câblage interne est touché.
Si vous touchez un ventilateur en marche alors que le châssis est ouvert, vous risquez de vous blesser,
de vous abraser ou de vous cisailler le bout des doigts.
Aucune procédure d'entretien nécessaire ne requiert l'ouverture du châssis.
Ne retirez PAS le couvercle du châssis.
N'installez PAS le périphérique dans des environnements où des enfants sont susceptibles d'être
présents.
ATTENTION
Risque de brûlures dues à la surface du châssis très chaude après une longue période
d'utilisation
Lorsque le châssis est entièrement équipé, la surface du châssis peut devenir très chaude après une
longue période de fonctionnement.
Si la surface du châssis est touchée après une longue période d'utilisation, cela peut provoquer des
brûlures de la peau.
Des gants de protection doivent être portés pour transporter un châssis entièrement équipé après une
longue période d'opération.
Veillez à ce que la distance avec l'opérateur soit suffisante, par exemple pour un montage sous une
table.
N'installez PAS le périphérique dans des environnements où des enfants sont susceptibles d'être
présents.

4.1 System Overview - Numbering of the Chassis Slots
The numbering of the slots in the chassis runs from bottom left to top right (2-/4-/6-slot chassis) and from
left to right (21-slot chassis). The slot numbering is relevant for the placement of an SNMP module in a
backplane chassis (see example) or a USB 2.0 stand-alone module in chassis without backplane (slot 2).

NOTICE
Too low power supply voltage
With Draco vario chassis 474-BODY6R-R1 a redundant power supply voltage is possible up to a current
of maximum 5 A (modules inclusive connected periphery). If the power supply voltage of the internal
power supply unit fails, the device's power supply voltage is secured via the 5 V external power supply
unit.
If there is no redundant power supply voltage and the current is above 5 A, the device is not supplied with
sufficient power supply voltage and fails.
Note the maximum current draw of the chassis (see chapter 6.3, page 35).
With a current of more than 5 A, use an external power supply unit. In this case, redundancy is
inapplicable.
NOTICE
Excessive current draw
The 6-slot Draco vario chassis with an internal power supply unit is not equipped with a fuse on its
primary side.
The protection against excessive current draw has to be provided by the electrical installation of the
