Step 3: Perform an SIB Swap Test

SIBs are hot-insertable and hot-removable.

NOTE: Before performing a swap test, always check for bent pins in the midplane and check the SIB for stuck pins in the connector. Pins stuck in the component connector can damage other good slots during a swap test.

Action

To perform a swap test on an SIB, follow these steps:

1. Take the SIB offline by doing one of the following

• Use the following CLI command:

user@host> request chassis sib slot number offline

• Press the online/offline button on the SIB faceplate. Press and hold down the button until the green ONLINE LED goes out (about 5 seconds).

2. Have ready an antistatic mat placed on a stable, flat surface.
3. Attach an electrostatic discharge (ESD) wrist strap to your bare wrist, and connect the wrist strap to one of the ESD points on the chassis.
4. Loosen the captive screws on the ejector handles on each side of the SIB faceplate.
5. Flip the ejector handles outward to unseat the SIB.
6. Grasp both ejector handles, pull firmly on the SIB, and slide the SIB about three-quarters of the way out of the chassis.
7. Move one of your hands underneath the SIB to support it, and slide it completely out of the chassis.
8. Hold the replacement SIB by placing one hand underneath to support it and the other hand on one of the ejector handles on the SIB faceplate.
9. Carefully align the sides of the SIB with the guides inside the chassis.
10. Slide the unit into the chassis, carefully ensuring that it is correctly aligned.
11. Grasp both ejector handles and press them inwards to seat the SIB.
12. Tighten the captive screws on the ejector handles.
13. Bring the SIB online by doing one of the following

• Use the following CLI command:

user@host> request chassis sib slot number online

• Press the offline/online button until the green ONLINE LED lights to bring the SIB online.
