Safety
1.1.
All plug-in modules and blank plates are part of the fire
enclosure and must only be removed when a replacement
can be immediately added. The system must not be run
without all units in place. In order to comply with applicable
safety, emission and thermal requirements no covers should
be removed.
Permanently unplug the unit if you think that it has become
damaged in any way and before you move it.
• An enclosure can weigh up to 36kg (79.2lb). Do not try to
lift it by yourself.
• The unit must only be operated from a power supply input
voltage range of 100–240 VAC, 50-60 Hz.
• The plug on the power supply cord is used as the main
disconnect device. Ensure that the socket outlets are located
near the equipment and are easily accessible.
• The power connection must always be disconnected prior to
removal of a PSU module from the enclosure.
• A safe electrical earth connection must be provided to the
power cord. Check the grounding of the enclosure before
applying power.
• Provide a suitable power source with electrical overload
protection to meet the requirements laid down in the technical
specification.
• This equipment is intended to operate with two working
PSUs installed in the Power Supply Module. Before removal/
replacement of a PSU disconnect all power for isolation.
• A faulty PSU must be replaced with a fully operational one
within 24 hours.
Caution:
If this equipment is used in a manner not specified
by the manufacturer, the protection provided by the equipment
may be impaired.
Warning:
Do not remove covers from the PSU. Danger of electric
shock inside. Return the PSU to your supplier for repair.
Caution:
The RJ45 sockets on the motherboard/PCI cards
are for Ethernet connection only and must not be connected to a
telecommunications network.
Warning:
The enclosure top cover must be secured, when
the enclosure is in normal use, by rotating the lock 90° to the
‘locked’ position. This is to prevent users/operators from
accessing the service areas.
Rack System Precautions
1.2.
The following safety requirements must be considered when the unit
is mounted in a rack.
• The rack design should incorporate stabilizing features
suitable to prevent the rack from tipping or being pushed
over during installation or in normal use.
• When loading a rack with the units, fill the rack from the
bottom up and empty from the top down.
• The rack design should take into consideration the maximum
operating ambient temperature for the unit, which is 35°C.
• The system must be operated with low pressure rear
exhaust installation (back pressure created by rack doors
and obstacles not to exceed 5 pascals (0.5mm water gauge)).
• The rack should have a safe electrical distribution system.
It must provide over-current protection for the unit and must
not be overloaded by the total number of units installed in
the rack. Consideration of the electrical power consumption
rating shown on the unit’s nameplate should be used when
addressing these concerns.
• The electrical distribution system must provide a reliable
earth for each unit an the rack.
• Each power supply in each unit has an earth leakage
current of 0.75mA. The design of the electrical distribution
system must take into consideration the total earth leakage
current from all the power supplies in all the units. The rack
will require labelling with
“HIGH LEAKAGE CURRENT. Earth
connection essential before connecting supply”.
