Installing a T640-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 Platform 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 TX Matrix Platform Hardware Guide. |
To install a T640-SIB into the rear of the chassis (see Installing a T640 Standard SIB or Standard SIB Version B):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see T640 Preventing Electrostatic Discharge Damage.
- Place one hand under the bottom edge of the T640-SIB and one hand around the top of the T640-SIB faceplate.
- If applicable, remove the protective tape covering each T640-SIB fiber-optic array adapter.
- Remove the dust covers from the fiber-optic array cable connectors. To remove a dust cover, loosen the thumbscrew and captive screw on the connector. (Use the supplied small slotted screwdriver to loosen the captive screw.) Store the dust covers in a dust-free resealable plastic bag.
- Install the cable connector to the fiber-optic array adapter. Align
the connector with the fiber-optic array adapter, and carefully press
it into the adapter until it stops. The cable connector and adapter
are keyed to ensure proper mating.
Note: The optics in a fiber-optic array adapter are spring loaded, so you must continue to apply force to a fiber-optic array cable connector or loopback connector while securing it to a TX-SIB or T640-SIB adapter.
Warning: Do not look directly into a fiber-optic array adapter or a connector at the end of a fiber-optic array cable attached to an adapter. The fiber optics emit laser light that can damage your eyes.
- Partially tighten the thumbscrew and captive screw on the fiber-optic array cable connector. (Use the supplied small slotted screwdriver to tighten the captive screw.) Alternate between the thumbscrew and captive screw until the cable connector is secured to the adapter.
- Use one
of the following methods to bring the T640-SIB online:
- Press and hold the online/offline button on the faceplate until the green OK LED next to the button blinks.
- Issue the following CLI command:
user@host> request chassis sib lcc number slot slot-number online
- Check the LEDs on the T640-SIB faceplate to verify that
the SIB is functioning normally.
- The green OK LED should light steadily a few minutes after the T640-SIB is installed.
- If the FAIL LED is lit steadily, remove and install the T640-SIB again (see Removing a T640-SIB and this procedure). If the FAIL LED still lights steadily, the T640-SIB is not functioning properly. Contact your customer support representative.
- Check the status of the T640-SIBs. Issue
the following CLI commands:
user@host> show chassis environment sib lcc numberFor more information and sample output from these commands, see theJunos System Basics and Services Command Reference.
