Maintaining the PTX5000 Switch Interface Boards

Maintaining the PTX5000 Switch Interface Boards

Purpose

For optimum performance, verify the status of the Switch Interface Boards (SIBs).

Action

On a regular basis:

  • Check the LEDs on the SIB faceplate and craft interface.

    During normal operations:

    • The green OK LED on the SIB faceplate is lit.

    • The yellow FAIL LED on the SIB faceplate is not lit.

  • Issue the show chassis fabric topology command. During normal operations, the output for the command shows that the state of the online SIBs and FPCs links are in the OK state.

  • Issue the show chassis environment sib command.

Replacing a PTX5000 Switch Interface Board

Replace the PTX5000 Switch Interface Boards (SIBs) by following the procedures described in the following sections.

Removing a PTX5000 Switch Interface Board

Nine SIBs are installed in the PTX5000. The SIBs are located in the rear of the chassis in the slots marked SIB0 through SIB8. Each SIB can weigh up to 10.4 lb (4.7 kg).

To remove the SIBs (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Twist the ejector handles counterclockwise to unseat the SIB.
  4. Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
  5. Place one hand underneath the 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 PTX5000 Switch Interface Board

Each SIB can weigh up to 10.4 lb (4.7 kg). To install a SIB (see Figure 2):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Place one hand underneath the SIB to support it. With the other hand, hold one of the ejector handles on the SIB faceplate.
  3. Carefully align the sides of the SIB with the guides inside the chassis.
  4. Slide the SIB into the chassis, carefully ensuring that it is correctly aligned.
  5. Twist the ejector handles clockwise until they stop.
  6. Bring the SIB online using one of the following methods:

    • Press and hold the ONLINE/OFFLINE button on the SIB faceplate. The green OK LED on the faceplate begins to blink. Hold the button down until the LED blinks.

    • Issue the following CLI command on the PTX5000:
