The ADP adapters are both used for rolling the pins of Sun/Cisco pinned equipment (i.e., like SLC) to be able to use a standard Cat5/6 cable. Typical use for the two adapter lengths in parallel would be when the ADP adapter needs to be placed at the device port end of a high port density console server (i.e., 32 or 48 port SLC). This will allow for more tolerance between cables/adapters without crowdingThe ADP adapters are both used for rolling the pins of Sun/Cisco pinned equipment (i.e., like SLC) to be able to use a standard Cat5/6 cable.
