Replacing a card

CAUTION:
• The cards on the routers are hot swappable. However, to remove the only MPU on the router, you
must first power off the router.
• To replace an MPU or service module, first remove all its cables.
• Replace all Type-A switching fab
information, see "Appendix B FRUs and compatibility matrixes."
The replacement procedure is the same for the cards installed in horizontal or vertical slots. The
following procedure replaces a card in a horizontal slot.
To replace a card:
1. Prepare an antistatic mat to place the removed card.
2. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
For more information, see "Attaching an ESD wrist strap."
3. Use a Phillips screwdriver to loosen the captive screws on the card.
4. Press the ejector buttons on the ejector levers to release the ejector levers. (This step is
applicable only to a switching fabric module with ejector buttons on the ejector levers.)
