2.3.6.3 Removing a DDR2 DIMM
If you are returning the DIMM or the blade server for service, or if you are replacing
a DIMM with another DIMM, remove the DIMM from the Sun Netra CP3250 blade
server.
Note – Safely store the original factory-shipped DIMM and related DIMM
packaging. Store any removed DIMM in the new DIMM packaging.
To remove a DIMM from the Sun Netra CP3250 blade server, perform the following
steps:
1. Access the blade server by performing one of the following procedures:
■ If the Sun Netra CP3250 blade server is installed in an ATCA shelf, remove the
blade server from the shelf as explained in Section 2.3.3, “Removing the Netra
CP3250 Blade Server” on page 2-18.
■ Remove the Sun Netra CP3250 blade server from its antistatic envelope and place
it on an ESD mat near the ATCA shelf.
If an ESD mat is not available, you can place the blade server on the antistatic
envelope in which it was packaged.
Caution – Do not place blade servers on top of an antistatic bag unless the outside
of the bag also has antistatic protective properties.
2. Take antistatic precautions: Attach and electrically ground the wrist strap.
Caution – Always wear a grounded antistatic wrist strap when handling DIMMs.
3. Simultaneously pull both spring retainer clips outward from the slot for the
DIMM you want to remove.
4. Grasp the DIMM by the edges, and carefully pull it out of its connector.
Place it in an antistatic bag.
