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.
To remove a T640-SIB (see "Removing a T640 Standard SIB or Standard SIB Version
B" on page 212):
Have ready a replacement SIB or blank panel, an antistatic mat, and one dust cover
1.
for the fiber-optic array cable connector you remove from the T640-SIB.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to an approved ESD grounding point.
Ensure that the fiber-optic array cable connectors plugged into the T640-SIB are
3.
labeled so you can reconnect them correctly.
Use one of the following methods to take the T640-SIB offline:
4.
Issue the following CLI command:
user@host> request chassis sib lcc number offline slot slot-number
For more information about the command, see the Junos OS System Basics and
Services Command Reference.
Press and hold the online/offline button on the craft interface that corresponds to
the T640-SIB. Hold the button down until all of the LEDs surrounding the button
are not lit.
Remove the fiber-optic array cable connector from the fiber-optic array on the
5.
faceplate of theT640-SIB.
WARNING: Do not look directly into a connector at the end of a fiber-optic
adapter orfiber-optic array cable connector attached to an adapter. The
fiber optics emit laser light that can damage your eyes.
Install a dust cover on the cable connector you removed from the T640-SIB. Align
6.
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.)
Move the fiber-optic array cables to the side of the T640-SIB so they do not interfere
7.
with the removal of the T640-SIB.
Simultaneously turn both ejector handles on the top and bottom of the faceplate
8.
counterclockwise to unseat the T640-SIB.
