{{Admon/caution|Do not connect Ethernet and Serial ports|Ethernet and serial connections in the EHL both use RJ-45 cables. Never connect the two, because they use incompatible voltage levels and signaling. RED cables must be used for serial connections and for nothing else; only non-RED cables shall be used for ethernet connections.}}
== Testing ==
[[Image:Acs32.png|thumb|widthpx| ]]
Testing of the Cyclades ACS32 involved crossing the RX and TX of two [DB9 to RJ45] converters (which are in turn connected to cat5 cables between the converter and the port on the Cyclades). This is done by connecting pin 2 of connector A to pin 3 of connector 3, and vice versa.
The ports on the Cyclades are then configured to accept SSH connection, and enabled.
Make sure the ports are assigned the correct privilege group to connect to them, and ssh to them in the fashion shown on the enclosed PNG.
Result: What you type in the SSH connection of one session, should appear on the ssh session of the corresponding port connected by the crossover cable. After testing that all ports can transmit and receive properly, one can conclude that the ports seem to be in working order.
