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.
To remove a fiber-optic array cable:
Bring the interface connected by the fiber-optic array cable offline using one of the
1.
following methods:
Issue the following CLI command:
user@host> request chassis sib slot slot-number lcc lcc-number offline
The slot number can be from 0 through 4 and corresponds to the TX-SIB chassis
slot. The LCC number can be 0 through 3 and corresponds to the TX-SIB adapters
labeled through
LCC0
Press and hold the online/offline button next to the TX-SIB adapter until the
LED is not lit.
Press and hold the online/offline button on the T640-SIB faceplate until the
LED is not lit.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Remove the fiber-optic array cable connectors from the TX-SIB and T640-SIB. To
3.
remove a cable connector, partially loosen the thumbscrew and captive screw on the
fiber-optic array cable connector. (Use the supplied small slotted screwdriver to
loosen the captive screw.) Alternate between the thumbscrew and captive screw
until the cable connector is removed from the adapter.
Install a dust cover on each of the two removed cable connectors. Align the dust cover
4.
with the cable connector and carefully press them together until they stop. The cover
and the cable connector are keyed to ensure proper mating. Secure the dust cover by
tightening the thumbscrew and captive screw on the connector. (Use the supplied
small slotted screwdriver to tighten the captive screw.)
Remove the fiber-optic array cable. If the cable is greater than 10 m long, we
5.
recommend that you reinstall the pulling-eye assembly on one end of the cable to
facilitate pulling the cable through the raceway.
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
