Replacing an MX2000 SFB

 

Removing an MX2000 SFB

To remove an SFB (see Figure 1 and Figure 2):

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 grounding points on the chassis.
  3. Open the ejector handles outward simultaneously to unseat the SFB.
  4. Grasp the ejector handles, and slide the SFB about halfway out of the chassis.Caution

    The weight of the SFB is concentrated in the back end. Be prepared to accept the full weight—up to 12 lb (5.45 kg)—as you slide the SFB 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.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.

  7. If you are not replacing the SFB immediately, install a blank panel over the empty slot.

Installing an MX2000 SFB

To install an SFB (see Figure 3):

Caution

Before removing or replacing an SFB, ensure that the ejector handles are stored horizontally and pressed toward the center of the SFB.

Caution

If one of the SFBs fails, do not remove the failed SFB until you have a replacement or blank panel to install.

  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. Take each SFB to be installed out of its electrostatic bag, and identify the slot on the SFB where it will be connected.
  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. Place the ejector handles in their proper position, vertically and toward the center of the board.

  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 environment sfb command:
    user@host> show chassis environment sfb
