Removing a TX Matrix Fiber-Optic Array Cable
 | 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
following methods:
- Issue the following CLI command:
user@host> request chassis sib slot slot-number lcc lcc-number offlineThe 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 LCC0 through LCC3.
- Press and hold the online/offline button next to the TX-SIB adapter until the RX LED is not lit.
- Press and hold the online/offline button on the T640-SIB faceplate until the RX LED is not lit.
- Issue the following CLI command:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect 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 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 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 recommend that you reinstall the pulling-eye assembly on one end of the cable to facilitate pulling the cable through the raceway.
