Installation precautions
Follow these precautions when installing the unit.
Attention: Before starting any installation or maintenance procedure, refer to
“Safety notices” on page xi.
Attention: Do not install the device in an environment where the operating
ambient temperature might exceed 40° C (104° F).
Attention: Make sure the air flow around the front, sides, and back of the device
is not restricted.
Attention: Never leave tools inside the chassis.
Lifting precautions
Attention: Do not use the handles on the power supply units to lift or carry the
device.
See “Rack safety” on page xviii before installing this product in a rack.
Power precautions
Attention:
Make sure you insert the power supply right-side up. It is possible to
insert the supply upside down, although the supply will not engage with the
power backplane when upside down.
Attention: Remove the power cord from a power supply before you install it in
or remove it from the device. Otherwise, the power supply or the device could be
damaged as a result. (The device can be running while a power supply is being
installed or removed, but the power supply itself should not be connected to a
power source.)
Attention: The power supply is designed exclusively for use with the c-series
switches. The power supply produces extensive power. Installing the power supply
in a device other than the c-series switches will cause extensive damage to your
equipment.
Attention: Power supplies are hot swappable. However, you should disconnect
the power supply from AC power before installing or removing the supply. The
device can be running while a power supply is being installed or removed, but the
power supply itself should not be connected to a power source. Otherwise, you
could be injured or the power supply or other parts of the device could be
damaged.
Preparing the installation site
For each device that you install in a rack, you must provide four standard #12-24
pan-head screws with which to mount and secure the chassis. Before performing
this task, you should have an assembled Telco rack and a #2 Phillips-head
screwdriver.
