Replacing a Card

Replacing a Card

Context

  • Replacing a card interrupts services. Therefore, save the configurations before replacing the card.
  • To avoid damages to the card, do not touch the electronic components on the card during the replacement.
  • Unused cards or parts must be placed in ESD bags. Do not pack cards with common foam materials, plastic bags, paper bags, or other packing materials without the ESD prevention function.
  • Vacant slots in the router must be covered with filler panels.
NOTE:

The methods for replacing SIC, WSIC, XSIC, and SRU cards on routers are the same. The following procedure replaces a SIC card on an AR2240 router.

Tools

  • Phillips screwdriver
  • ESD wrist strap

Procedure

  1. Wear an ESD wrist strap. Ensure that the ESD wrist strap is grounded and in a close contact with your wrist.
  2. Remove cables from the card to be replaced, and record mappings between cables and interfaces on the card to ensure correct cable connections on the new card.
  3. Remove the old card.
    1. Loosen the captive screws on both sides of the card and rotate the ejector levers outward.
    2. Gently pull the card out of the slot along the guide rails.
