Safety Guidelines 3
Electrical Safety
Ensure to follow these electrical precautions:
• The 2U chassis must only be operated from a power supply input voltage range of 100–240 VAC,
50–60 Hz.
• The 5U chassis must only be operated from a power supply input voltage range of 200–240 VAC,
50–60 Hz.
• Provide a suitable power source with electrical overload protection to meet the requirements in
the technical specification.
• The power cord must have a safe electrical earth connection. Check the connection to earth of the
chassis before you switch on the power supply.
IMPORTANT: The chassis must be grounded before applying power.
• The plug on the power supply cord is used as the main disconnect device.
• The 2U and 5U chassis are intended to operate with two PSUs.
• Observe the power-supply disconnection caution label affixed to PSUs.
CAUTION: Do not remove covers from the PSU – there is a danger of electric shock inside.
• Return the PSU to your supplier for repair.
• When bifurcated power cords (Y-leads) are used, these cords must only be connected to a supply
range of 200–240 VAC.
IMPORTANT: The RJ-45 socket on the expansion input/output modules (IOMs) is for the Ethernet
connection only and must not be connected to a telecommunications network.
Rack System Safety Precautions
The following safety requirements must be considered when the chassis is mounted in a rack.
• The rack construction must be capable of supporting the total weight of the installed chassis.
The 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 chassis, fill the rack from the bottom up; and empty the rack from the
top down.
• Always remove all CRUs to minimize weight, before loading the chassis into the rack.
• Do not try to lift the chassis by yourself.
