Introduction
When installing the equipment observe the following:
3.1
Possibility of personal injury. Keep your fingers away from the rotating fan
blades. Pull the fan-tray module by the thumbscrews only and wait for the fan
blades to stop spinning before you attempt to remove the fan-tray module
completely from the chassis.
Possibility of personal injury. The Alcatel-Lucent 1677 SONET Link requires
at least three people to support, align, and attach it to an equipment rack. To
prevent equipment damage or personal injury, make sure you have enough
help.
Possibility of personal injury. To prevent personal injury and equipment
damage due to unbalanced loading of the equipment rack or cabinet, make
sure the equipment rack or cabinet is properly secured to the floor, ceiling,
or other rigid structure before mounting the Alcatel-Lucent 1677 SONET Link
in it. For approved methods of securing the equipment rack, read the
equipment-rack installation instructions or contact the equipment-rack
manufacturer.
Take appropriate safety precautions when performing procedures on
3.2
electrical equipment. Hazardous electrical potentials are present when system
power is on.
Some procedures in this manual require working with small
3.3
conductive objects, such as screwdrivers, fuses, washers, screws, and nuts.
When working on a chassis at the top of an equipment rack, a dropped object
that falls into a lower chassis can cause physical damage and electrical short
circuits. To prevent this, place a piece of paper or other cover over the lower
chassis to catch fallen objects. Remove the paper or other cover when work is
complete.
Possibility of personal injury. Install the Alcatel-Lucent 1677 SONET Link in
a restricted-access area only. Entrance to a restricted-access area is
intended for qualified or trained personnel and access to it is controlled by a
locked barrier.
