5.36 Connect the shelf-ground cable to the rack housing the Tellabs 7300 NE
by performing the following steps:
__ 1. Prepare the point of connection on the rack by removing any paint.
Use only a non-metallic product, such as 3M synthetic steel wool, to
prevent an accumulation of steel fibers that can short-circuit the
equipment.
__ 2. Place a small amount of oxidation preventive grease compound over
the prepared area.
__ 3. Connect one end of the wire with lug to the Tellabs 7300 NE shelf
ground connection. Refer to Figure 5.9, page 2-55 or Figure 5.10,
page 2-55. Use an M-5 screw to attach.
__ 4. Single-crimp the copper wire to a #10-12 AWG lug at the rack end.
__ 5. Depending upon rack type, use the appropriate screw to terminate the
opposite end of cable to the area of the rack that was prepared in step
1, page 2-56.
Installing the Modules (Tellabs 7345 Switch only)
5.37 If module installation is required, follow the procedures in this section to
install modules in the Tellabs 7345 shelf.
5.38 Always use the 10G Switch module’s ejector latches (located on the front
of the module) when installing or removing it from its slot. Make sure that the
module is firmly seated after it is installed. Do not try to force the module into or out
of a slot by pushing or pulling on the module’s front panel.
5.39 To install a module using the ejector latches, first pull the latches outward
from the front panel, slide the module into the shelf until the latches are at the edge
of the shelf, and then seat the module fully by pulling the latches inward.
Warning:
Failure to connect the shelf to a high-quality ground connection may reduce the
performance and availability of the shelf and the equipment that connects to it.
Improper grounding may increase electrical noise in the shelf, causing data loss
and other performance failures.
Warning:
Electrostatic discharge (ESD) may damage sensitive electronic components
resulting in a traffic-affecting condition. Ensure that plug-in modules are stored
in static preventive material. Do not touch any components on the modules.
Handle modules by the edges or front panel. Always wear a properly grounded
wrist strap when handling, removing, or inserting a module and when touching
the equipment shelf or cables. ESD protective flooring, used with proper ESD
footwear, may be used as an alternative to a wrist strap. Check ESD wrist straps
and footwear daily to verify performance.
