NOTE: Ensure that the ejector handle tabs are properly mated inside their
corresponding chassis slots before you tighten the captive screws on the
ejector handles. You might have to close and open the handles a few times
before the tabs catch the slots.
NOTE: After you replace a SIB with a T640-SIB, do not replace another SIB
in the T640 router until you have successfully connected and tested the
T640-SIB you just installed.
CAUTION: While you install the TX Matrix router or replace a fiber-optic array
cable, small deposits of oil, dust, and debris can enter the TX-SIB and
T640-SIB fiber-optic array adapters, the fiber-optic array cable connectors,
and the loopback connectors and adapters. We recommend that you clean
the optics in these components, as well as the loopback connector and
adapter dust covers, immediately before connecting them. For cleaning
instructions, see "Cleaning the TX Matrix and T640 Fiber-Optic Components
Overview" on page 200.
After you convert a switching plane from a SIB to a T640-SIB, you connect a fiber-optic
array cable to it and test it using the following procedure (see Table 4 on page 14 for the
T640-SIB adapter connections):
Using the labels you attached to the ends of the fiber-optic array cables, identify the
