To avoid equipment damage, always unplug the card first before you disconnect the
MSS-ODU cable (at MSS or ODU side).
1.7 Fan, equipment rack, and equipment cabinet
When installing the equipment observe the following:
Danger:
•Keep your fingers away from the rotating fan blades. Pull the fan-tray card by the
thumbscrews only and wait for the fan blades to stop spinning before you attempt to
remove the FAN card completely from the MSS-4/8 shelf.
•The 9500 MPR may require two people to support, align, and attach it to an equipment
rack. To prevent equipment damage or personal injury, make sure you have enough help.
•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 correctly secured
to the floor, ceiling, or other rigid structure before mounting the 9500 MPR in it. For
approved methods of securing the equipment rack, read the equipment-rack installation
instructions or contact the equipment-rack manufacturer.
1.8 Electrical precautions
Take appropriate safety precautions when you perform procedures on electrical
equipment. Hazardous electrical potentials are present when system power is on.
Some procedures in this manual require working with small conductive objects, such
as screwdrivers, fuses, washers, screws, and nuts. When working on a shelf at the
top of an equipment rack, a dropped object that falls into a lower shelf can cause
physical damage and electrical short circuits. To prevent this, place a piece of paper
or other cover over the lower shelf to catch fallen objects. Remove the paper or other
cover when work is complete.
