Midplane Filler Strips

The Sun Datacenter Switch 3456 ships with plastic filler strips affixed to the
midplane. These strips protect the pins of the midplane connectors during the
installation process. The filler strips are secured in place by short pieces of rubber
tubing, which are inserted over the midplane alignment pins. See
