Removing an MX2008 SFB

To remove an MX2008 Switch Fabric Board (SFB) (see Figure 1):

Note

You can remove the SFB as a unit.

Caution

Before removing an SFB, ensure that you know how to operate the ejector handles properly to avoid damage to the equipment.

  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. Open the ejector handle outward to unseat the SFB.
  4. Grasp the ejector handle, and slide the SFB about halfway out of the chassis.
  5. Place one hand underneath the SFB to support it, and slide it completely out of the chassis.
  6. Place the SFB on the antistatic mat or into an antistatic bag.
  7. If you are not replacing the SFB immediately, install a blank panel over the empty slot.

Installing an MX2008 SFB

To install an SFB (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. Remove the SFB from the electrostatic bag.
  3. Carefully align the sides of the SFB with the guides inside the chassis.
  4. Slide the SFB into the chassis until you feel resistance, carefully ensuring that it is correctly aligned.
  5. Grasp the ejector handle, and gently close it inward until the SFB is fully seated.
  6. Check the LEDs on the SFB faceplate to verify that it is functioning normally.
    • The green OK/FAIL LED should light steadily a few minutes after the SFB is installed.

    • If the OK/FAIL LED is red, remove and install the SFB again. If the OK/FAIL LED still lights steadily, the SFB is not functioning properly. Contact your customer support representative. See Contacting Customer Support.

  7. Check the status of the SFB by using the show chassis sfb command:
    user@host> show chassis sfb
