Inspecting the System
Note Because of the small size of the pins on the DB-60 serial connector, attempting to
manufacture your own serial cables is not recommended.
Asynchronous Serial Connections
The asynchronous serial ports use one or two 68-pin connectors located on the far left of
the rear panel. Each of the connectors provides eight asynchronous ports. The lower port is
labeled ASYNC 1–8, and the upper port is labeled ASYNC 9–16. Breakout cables that
divide into eight RJ-45 connectors each are connected to the asynchronous connectors.
RJ-45-to-DB-25 adapters are used to connect to external devices such as modems, printers,
or terminals. RJ-45-to-DB-25 adapters are available from Cisco for either DCE or DTE
connections. See the appendix “Cable Specifications” to select the correct adapter, and for
pinouts for the RJ-45-to-DB-25 adapters.
Inspecting the System
Do not unpack the access server until you are ready to install it. If the final installation site
will not be ready for some time, keep the chassis in its shipping container to prevent
accidental damage. When you have determined where you want the access server installed,
proceed with the unpacking.
The access server, cables, UniverCD or printed publications, and any optional equipment
you ordered might be shipped in more than one container. When you unpack each shipping
container, check the packing list to ensure that you received all of the following items:
• Access server
• 6-foot (1.8-meter) power cord
• Jackscrews for the AUI connector
• Console and auxiliary cabling kit (two RJ-45 roll-over cables, one terminal adapter, and
one modem adapter)
• Optional equipment (such as network interface cables, and asynchronous breakout
cables)
