Overview" on page 200.
To install a fiber-optic array cable:
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect

the strap to one of the ESD points on the chassis.
Using the supplied label sheets, attach a label to each end of the replacement

fiber-optic array cable to help you identify the corresponding TX-SIB adapter and
T640-SIB. The labels are marked with the chassis ID and the switching plane
(separated with a slash). For example, use the label marked
connection between adapter
22 on page 112 lists the connections between TX-SIBs and T640-SIBs.
NOTE: You must use the same length for every fiber-optic array cable
from a particular T640 router to the TX Matrix router. However, you do
not need to use the same length for all fiber-optic array cables within a
routing matrix.
Route the end of the fiber-optic array cable that plugs into the TX-SIB over the

TX Matrix router to the TX-SIB adapter. If you have installed the optional cable shelf
assembly, use the lowest shelf to support a cable destined to any TX-SIB adapter
labeled , use the next shelf up to support a cable destined to any TX-SIB adapter

NOTE: If you have previously routed a spare fiber-optic array cable
between the TX Matrix router and T640 router, some of the steps in this
procedure have already been performed.
CAUTION: You must maintain a minimum bend radius of 2 in. (5.1 cm).
We recommend that you maintain a bend radius of 10 in. (25.4 cm). If you
must bend a fiber-optic array cable to a 2-inch radius, we recommend
that you do not use more than two such bends.
CAUTION: Plastic wrap-ties can damage or crimp the fiber-optic array
cables (see Figure 117 on page 264). We recommend that you use soft band
straps to secure fiber-optic array cables.
