•
Take care when connecting units to the supply circuit so that wiring is not overloaded.
•
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority
or an electrician if you are uncertain that suitable grounding is available.
•
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to
support the weight of the unit.
•
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
•
When installing or replacing the unit, the ground connection must always be made first and disconnected
last.
•
The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide
the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.
•
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments.
Review Installation Guidelines
Before installing the chassis, verify that these guidelines are met:
•
Site is properly prepared so that there is sufficient room for installation and maintenance. For specifications
on the clearances required for chassis installation, see
Clearance Requirements, on page 62
.
•
Operating environment is within the ranges listed in
Environmental and Physical Specifications, on
page 59
•
Chassis is mounted at the bottom of the rack if it is the only unit in the rack.
•
When mounting the chassis in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
•
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
chassis in the rack.
•
Airflow around the chassis and through the vents is unrestricted.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
Procure Tools and Equipment
Obtain these necessary tools and equipment for installing the chassis:
•
Number 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis.
•
3/16-inch flat-blade screwdriver
•
Tape measure and level
