Figure 164: Removing a SIB

Use this procedure to install a T640-SIB in a T640 router that is connected to a TX Matrix
platform. To convert the switching plane from standard SIBs to T640-SIBs, see the
procedures in the
TX Matrix Router Hardware Guide
NOTE: While you install the T640-SIB or replace a fiber-optic array cable,
small deposits of oil and dust can enter the T640-SIB fiber-optic array
adapters, the fiber-optic array cable connectors, and the loopback connectors
and adapters. We recommend 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 the
Guide .
