Replacing a TXP-F2S SIB
Removing a TXP-F2S SIB
The TXP-F2S SIBs are located in the front of the chassis in slots SIB0 through SIB15. Each TXP-F2S SIB weighs approximately 3.4 lb (1.5 kg).
TXP-F2S SIBs are hot-insertable and hot-removable. When you remove a TXP-F2S SIB, traffic forwarding continues without any degradation as long as four TXP-F2S SIBs remain in the chassis.
To remove a TXP-F2S SIB (see Figure 1):
- Have ready an antistatic mat for the TXP-F2S SIB, and one dust cover for each fiber-optic array cable you remove from the TXP-F2S 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.
- Use one of the following methods to take the TXP-F2S
SIB offline:
- Issue the following CLI command:
user@host> request chassis sib f2 slot slot-number offlineFor more information about the command, see the Junos System Basics and Services Command Reference.
- Press and hold the ONLINE/OFFLINE button on the the TXP-F2S SIB faceplate. Hold the button down until all of the LEDs are not lit.
- Issue the following CLI command:
- Release the latch on the ejector handle of the TXP-F2S SIB faceplate.
- Flip the ejector handle outward to unseat the TXP-F2S SIB.
- Grasp the ejector handle, pull firmly, and slide the TXP-F2S SIB about halfway out of the chassis.
- Place one hand underneath the TXP-F2S 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.

Installing a TXP-F2S SIB
To install a TXP-F2S SIB into the front of the chassis (see Installing a TXP-F13 SIB):
![]() | Caution: Be prepared to support the weight of the TXP-F2S SIB (approximately 35 lb [15.9 kg]) before you lift it. |
- Have ready a replacement TXP-F2S SIB or TXP-F2S 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.
- Lift the TXP-F2S SIB into place and carefully align first the bottom, then the top of the TXP-F2S SIB with the guides inside the card cage.
- Carefully slide the TXP-F2S SIB all the way into the card cage until you feel resistance.
- Grasp the ejector handle and rotate inward TXP-to seat the TXP-F2S SIB until the ejectors latch into the faceplate.
- Use one of the following methods to bring the TXP-F2S
SIB online:
- Press and hold the ONLINE/OFFLINE button on the the TXP-F2S SIB faceplate until the green OK LED is lit. The green OK LED should light steadily a few minutes after the TXP-F2S is installed.
- Issue the following CLI command:
user@host> request chassis sib f2 slot slot-number online
Verify that the TXP-F2S SIB is online and functioning normally:
- Verify that the TXP-F2SIB is online by issuing the show chassis sibs command.
- Verify that the green OK LED is lit steadily.
