Replacing a TXP-F13 SIB
Removing a TXP-F13 SIB
The TXP-F13 SIBs are located in the rear of the chassis in slots SIB0 through SIB15. Each TXP-F13 SIB weighs approximately 17.0 lb (7.7 kg).
TXP-F13 SIBs in active data switching planes are hot-pluggable. TXP-F13 SIBs in a spare data switching planes are hot-insertable and hot-removable. When you remove a TXP-F13 SIB in a spare switching plane, traffic forwarding continues without any degradation as long as the TXP-F13 SIBs in the other four switching planes remain in the chassis and online. When you remove a TXP-F13 SIB in an active switching plane, traffic forwarding continues without any degradation in the active switching planes. However, removing a TXP-F13 SIB in an active switching plane causes performance degredation in that switching plane. To avoid performance degredation, you can take the switching plane offline before you remove a TXP-F13 SIB.
For more information about the commands for this procedure, see the Junos System Basics and Services Command Reference.
To remove a TXP-F13 SIB (see Figure 1):
- Have ready an antistatic mat for the TXP-F13 SIB, and one dust cover for each fiber-optic array cable you remove from the TXP-F13 SIB.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Ensure the fiber-optic array cables connected to to the TXP-F13 SIB are labeled so you can reconnect them correctly.
- Take the switching plane offline.
- Use one
of the following methods to take the TXP-F13 SIB offline:
- Issue the request chassis sib f13 slot slot-number offline command. For example:
user@host> request chassis sib f13 slot 6 offlineOnline initiated, use "show chassis sibs" to verify
- Press and hold the SIB ONLINE/OFFLINE button in the middle of the TXP-F13 SIB faceplate to take the TXP-F13 SIB offline. Press and hold the EVEN and ODD ONLINE/OFFLINE buttons on either side of the SIB ONLINE/OFFLINE button to take the connections to the TXP-T1600 SIBs offline. Hold the buttons down until all the LEDs on the faceplate are not lit.
- Issue the request chassis sib f13 slot slot-number offline command. For example:
- Remove each fiber-optic array cable (up
to eight) from the TXP-F13 SIB.

Warning: Do not look directly into a fiber-optic array port or a connector at the end of a fiber-optic array cable connected to a port. The fiber optics emit laser light that can damage your eyes.
- Install a dust cover on each cable you removed from the TXP-F13 SIB. Align the dust cover with the cable and carefully press them together until they stop. The cover and the cable are keyed to ensure proper mating.
- Move the fiber-optic array cables to the side of the TXP-F13 SIB so they do not interfere with the removal of the TXP-F13 SIB. You might need to remove the cables from the cable management system.
- Simultaneously turn both ejector handles on the left and right of the faceplate counterclockwise to unseat the TXP-F13 SIB.
- Grasp both ejector handles, pull firmly, and slide
the TXP-F13 SIB about three-quarters of the way out of the chassis.

Caution: Be prepared to support the weight of the TXP-F13 SIB before you slide it completely out of the chassis.
When the TX-SIB is out of the chassis, do not hold it by its ejector handles or edge connectors. They cannot support its weight.
- Place one hand underneath the TXP-F13 SIB to support
it and slide it completely out of the chassis. Place it on the antistatic
mat.

Caution: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.
- If you are not reinstalling a TXP-F13 SIB into the emptied TXP-F13 SIB slot within a short time, install a blank TXP-F13 SIB panel over the slot to maintain proper airflow in the TXP-F13 SIB card cage.

Installing a TXP-F13 SIB
To install a TXP-F13 SIB into the rear of the chassis (see Figure 2):
![]() | Caution: Be prepared to support the weight of the TXP-F13 SIB (approximately 17.0 lb (7.7 kg)) before you lift it. |
- Have ready a replacement TXP-F13 SIB or TXP-F13 SIB blank panel.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Locate the slot in the TXP-F13 SIB card cage in which you plan to install the TXP-F13 SIB.
- Place one hand under the bottom edge of the TXP-F13
SIB and one hand around the top of the TXP-F13 SIB faceplate.

Caution: When the TXP-F13 SIB is out of the chassis, do not hold it by its ejector handles or edge connectors. They cannot support its weight.
- Lift the TXP-F13 SIB into place and carefully align the left and right edges with the guides inside the card cage.
- Carefully slide the TXP-F13 SIB all the way into the card cage until you feel resistance.
- Simultaneously turn both left and right ejector handles clockwise to seat the TXP-F13 SIB.
- Remove the dust cover from covering each TXP-F13 SIB fiber-optic array port.
- Remove the dust covers from the fiber-optic array cable connectors.
- Clean the fiber-optic array ports and cables.

Caution: While you replace a fiber-optic array cable, small deposits of oil, dust, and debris can enter the TXP-F13 SIB and TXP-T1600 SIB fiber-optic array ports, the fiber-optic array cables. We recommend that you clean the optics in these components, as well as the dust covers, immediately before connecting them.
- Connect each cable (up to eight) to its corresponding TXP-F13 SIB
port. Align the cable with its corresponding TXP-F13 SIB port and
carefully press it into the port until it stops. The cable and port
are keyed to ensure proper mating.

Note: The optics in a fiber-optic array port are spring loaded, so you must continue to apply force to a fiber-optic array cable or loopback connector while securing it to a TXP-F13 SIB.
- Use one
of the following methods to bring the TXP-F13 SIB online:
- Press and hold the SIB ONLINE/OFFLINE button in the middle of the TXP-F13 SIB faceplate. The green OK LED should light steadily a few minutes after the TXP-F13 SIB is installed.
- Issue the following CLI command:
user@host> request chassis sib f13 slot slot-number online
Verify that the TXP-F13 SIB is functioning normally:
- Verify that the green OK LED is lit steadily.
- Verify that the TXP-F13 SIB is online by issuing the show chassis sibs command.
