Replacing a Card

Replacing a Card


Only the CE8860, CE8861, and CE8868 support pluggable cards. An applicable card can be installed in any slot of the switch.

This section uses a CE8860 switch as an example to describe the procedure of replacing a card. The CE8861 and CE8868 chassises have the same way as the CE8860 chassis.

  • Install filler panels in vacant slots. A switch is delivered with filler panels in slots 2 to 4. Slot 1 that has no filler panel is preferred for card installation.
  • When installing a card, slowly push it into the slot. If you feel resistance or find the card inclined, pull the card out and push it into the slot again. Do not push the card with force; otherwise, the connectors on the card and backplane may be damaged.
  • All cards are hot swappable.
  • Replacing a card will interrupt services on the card. Exercise caution when deciding to perform this operation.

Tools and Accessories

  • ESD wrist strap or ESD gloves


  1. Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  2. Record the cable locations on the old card and check whether the labels on the cables are correct and clear. If any label is unclear, make and attach a new label to the cable to ensure correct connection.
  3. Remove the cables or optical modules from the old card.
  4. Remove the card from the switch.
    1. Press the two green locking clips in the middle of the card to eject the ejector levers.
    2. Turn the ejector levers outward and slowly pull the card out.

    Place the replaced card in an ESD bag.

  5. Install the new card. For details, see Installing a Card.
  6. Connect cables or optical modules to the new card in accordance with the previous connections you have recorded.
  7. Checks whether the new card works normally.

    • Check the corresponding SLOT indicator on the power supply side.
      • Off: No card is present in the slot, a card is present but is not powered on, or the system is not running.
      • Slow blinking green: The card is running normally.
      • Fast blinking green: The card is powering on or resetting.
      • Steady red: A fault that affects services has occurred on the card. The fault cannot be rectified automatically and requires manual intervention.
    • Run the display device command on the switch to view the running status of the new card.

Follow-up Procedure

After replacing the card, collect all tools. If the replaced card is faulty, fill in the Repair Transmission Sheet and send the faulty card with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
